Abstract:
Abstract This contribution aims to examine the scientific relationship between Giuseppe Toaldo and Jérôme Lalande, focusing on two works by the French astronomer which Toaldo translated into Italian. The first text is the Abregé d’ Astronomie (Compendio d’Astronomia, Padova: Stamperia del Seminario, 1777), addressed to students of astronomy; the second one is the Astronomie des Dames (Astronomia delle Dame, [Venezia]: Giacomo Storti, 1796), written for a female public to which Toaldo interestingly added the appendix Astronomia de’ Gentiluomini (Venezia, 1797). These works clearly testify Toaldo’s deep interest in the teaching and spreading of astronomy, an interest Toaldo shared with Lalande. The contacts between the two astronomers we will be displaying will also allow us to make some hypothesis about two splendid globes, a terrestrial and a celestial one. It is unknown how they arrived in the library of the Episcopal Seminar of Padova, where they are preserved today.

Abstract:
Astronomia jest nauką niezależną od wiary, natomiast astrologia jest ściśle powiązana z wierzeniami religijnymi. Astronomia obserwuje kosmos, aby tworzyć teorie, astrologia ma wydźwięk praktyczny, jest sztuką panowania nad kosmosem, ma powiązanie z magią. Na ogół słowa mające w końcówce -logia (np. filologia, teologia) mają charakter bardziej teoretyczny, natomiast nazwy dziedzin bardziej praktycznych mają w końcówce -nomia (np. gastronomia). Tymczasem tutaj mamy sytuację odwrotną. Artykuł niniejszy zajmuje się kwestiami językowymi oraz tłem historycznym jedynie po to, aby odróżnić te dwie dziedziny i ukazać relację między astronomią i teologią. Treść artykułu została ułożona chronologicznie. Przedstawimy najpierw astronomię starożytną, uprawianą w Mezopotamii i w Grecji, a następnie zajmiemy się wykorzystaniem dorobku astronomii w teologii chrześcijańskiej. Ukażemy też powiązania astronomii z islamem.

Abstract:
It is not possible to sketch the history of astronomy by amateurs without first defining what the term “amateur astronomer” truly means. But we must avoid using “the benefit of hind-sight” to interpret the past in terms of a concept, the relevance of which has been perceived only during the course of the last one hundred years. In order to avoid the sophistry arising from such a purely imaginary history that is based on false conceptions, it is useful to examine amateur astronomy’s precise status, since its emergence in the dawn of classical science, by outlining the type of relationship that it has had with “professional” astronomy. In doing so, we can evoke some of the major developments in amateur astronomy, the scientific contributions of which, although often of high quality, have at times reached the very forefront of the discipline of astronomy.

Abstract:
Amateur astronomy in Poland has its own history dating from the 17th century to the present day. Before the 17th century, the term “amateur astronomer” loses its meaning. Otherwise we might pose the rather paradoxical question: “Was Copernicus an amateur?” and probably have to give the answer: “Yes, he was an amateur, being first a priest, a physician and a lawyer.” Let us leave him in peace and instead turn to more undoubted amateurs. The history can be divided into two general periods: before and after the creation of the Polish Amateur Astronomical Society, PA AS (Polskie Towarzystwo Milosników Astronomii – PTMA). Here we present 16 Polish amateur astronomers who contributed to astronomy from the 17th to the 20th centuries, except Jan Heweliusz – the greatest – who is discussed elsewhere (1). All are selected from a much larger group, the selection being made in accordance with the rules described in the very useful and practical “Criteria for identifying an astronomer as an amateur”, formulated by Tom Williams a few years ago and presented here (2). There is also a short history and current information about the PAAS. Finally, we summarize successes and failures of amateur astronomy in Poland and put some general questions about its future.

Abstract:
Let us begin by defining “amateur astronomer”. According to a dictionary, an amateur astronomer is “someone who loves astronomy, and cultivates it as a hobby”. At IAU colloquium 98 (The Contributions of Amateurs to Astronomy), Williams (1988) discussed this issue at length. He proposed that, to be an amateur astronomer, one must be an astronomer - able to do astronomy with some degree of skill; he then defined an amateur astronomer as “someone who carries out astronomy with a high degree of skill, but not for pay”.

Abstract:
Astronomy has developed in India since prehistoric times. However, astronomy’s first work appeared during the Vedanga Jyotisa era, written by Lagadha, the oldest literary book in India. Using qualitative methods with a library research approach, it was found that Indian astronomers researched Astronomy and wrote books. One of the books that first made Muslim scientists interested in the world of astronomy was the book Brāhmasphuṭasiddhānta, which was translated into Arabic by Al-Fazari (d. 796 AD) during the Caliphate of Al-Manṣūr from the Abbasid dynasty. Al-Fazari (d. 796 AD) became the first Muslim astronomer to compile Zij, with his calculations converted into the Hijri Calendar. After Al-Fazari (d. 796 AD) collected this Zij, other Zijs were born, which became the forerunners for the composition of the epimeris and other counts. Around the beginning of the 11th century, Al-Biruni (973-1048 AD) spread da'wah to India and introduced the study of Islamic astronomy in India.

Abstract:
Ilmu Astronomi adalah salah satu cabang bidang keilmuan yang melibatkan pengamatan benda-benda langit (Bintang, Planet, Komet, Nebula, Gugus Bintang atau Galaksi) serta fenomena – fenomena alam yang terjadi di luar atmosfer Bumi (Misal Badai Matahari, radiasi latar belakang kosmik). Di Indonesia jumlah bangunan yang memiliki fungsi sebagai Astronomy Centre hanya terdapat di DKI Jakarta yaitu Planetarium dan Observatorium Jakarta yang terletak di Jakarta Pusat. Di Provinsi Jawa Tengah belum terdapat sarana untuk mengakomodasi kegiatan astronomi, baik tingkat pelajar, mahasiswa maupun umum. Kabupaten Semarang dipilih karena mempunyai topografi berupa pegunungan dan jauh dari keramaian Kota Semarang yang cocok untuk menjadi tempat untuk melakukan pengamatan benda langit. Astronomy Center di Kabupaten Semarang merupakan suatu bangunan yang berfungsi untuk mewadahi suatu kebutuhan wisata edukatif dan mengenalkan ilmu pengetahuan astronomi kepada masyarakat umum dan sebagai bangunan yang mempunyai misi mengenalkan ilmu astronomi kepada masyarakat umum. Tujuan perancangan Astronomy Centre adalah untuk fasilitas edukasi yang bisa dijangkau dan memberikan pengetahuan kepada masyarakat, memiliki desain yang menarik. Dengan penekanan desain Arsitektur Metafora, dan di peruntukan untuk pelajar, mahasiswa maupun masyarakat umum baik domestik maupun mancanegara yang datang secara individual, group, maupun study tour yang hendak belajar tentang ilmu astronomi.

Abstract:
This dissertation is a collection of poems preceded by a critical preface. The preface considers Anthony’s Hecht’s long poem, “The Venetian Vespers,” and the ways in which the temporally unsettled situation of the poem’s speaker parallels a problem facing narrative-meditative poets. The preface is divided into two main sections that explore divisions of this larger conflict. The first discusses the origins and effects of the speaker’s uprootedness in time, and the ways in which he tries to both combat and embrace this dislocation by temporarily losing himself in the immediacy of observing visual art. In this section I connect the dilemma of the speaker, who wishes to escape his memory by focusing outwards, to the dilemma of a representational poet who, despite his position towards the past, must necessarily confront or recollect memories and emotions in order to create authentic descriptions or characters. The second section focuses on the production and appreciation of artistic works (both visual and literary) and how the meaning, production and appreciation of beauty are inseparable from its existence within the physical limits of time. Here I discuss the significance of Hecht’s character who is surrounded with beauty yet describes himself as a person who only observes and does not create anything. Through this character, I argue that Hecht reveals a fundamental conflict that exists between artistic creation and chronological time, and that his poem embodies a particular and paradoxical view of beauty that resonates deeply with the motivations and struggles of writing poems.

Abstract:
There are over 300 exoplanets detected through radial velocity surveys and photometric studies showing a tremendous variety of masses, compositions and orbital parameters. Understanding the way these planets formed and evolved within the circumstellar disks they were initially embedded in is a crucial issue. In the first part of this thesis we study the physical interaction between a gaseous protoplanetary disk and an embedded planet using numerical simulations. In order to trust the results from simulations it is important to compare different methods. However, the standard test problems for hydrodynamic codes differ considerably from the case of a protoplanetary disk interacting with an embedded planet. We have carried out a code comparison in which the problem of a massive planet in a protoplanetary disk was studied with various numerical schemes. We compare the surface density, potential vorticity and azimuthally averaged density profiles at several times. There is overall good agreement between our codes for Neptune and Jupiter-sized planets. We performed simulations for each planet in an inviscid disk and including physical viscosity. The surface density profiles agree within about 5% for the grid-based schemes while the particle codes have less resolution in the low density regions and weaker spiral wakes. In Paper II, we study hydrodynamical instabilities in disks with planets. Vortices are generated close to the gap in our numerical models in agreement with the linear modal analysis. The vortices exert strong perturbations on the planet as they move along the gap and can change its migration rate. In addition, disk viscosity can be modified by the presence of vortices. The last part of this thesis studies the mass transfer in symbiotic binaries and close T Tauri binary systems. Our simulations of gravitationally focused wind accretion in binary systems show the formation of stream flows and enhanced accretion rates onto the compact component.

Full text
Abstract:

In this work, the long-term evolution of globulettes, low-mass globules found in H II regions, is studied through numerical hydrodynamic simulations. It has been proposed by Gahm et al. (2007) that these clouds may form free-floating planetary mass objects due to shock compression, caused by heating from the intense UV radiation of the central OB star cluster. To address this possibility, lifetimes are calculated for three different 3D simulated cases, similar to globulettes found in the Rosette Nebula. A plane-parallel approximation of the radiation field is used, as well as an inhomogeneous initial density distribution. The ionizing radiation will cause the globulettes to photo-evaporate, creating a rocket acceleration effect from the mass ejected on the heated side of the cloud. For a typical globulette with an initial mass of 29.5 Jupiter masses a lifetime of 50 000 yrs is estimated. This estimate is compared to the analytical models of Mellema et al. (1998) and Bertoldi and McKee (1990) which suggest longer lifetimes; the discrepancy is attributed to fragmentation of the clouds in the numerical simulation, which is not adequately described by the models. Synthesized H-alpha images and lightcurves are presented, indicating that the bright rims of small clouds are only likely to be visible in dim parts of the Rosette Nebula. The morphology of simulated clouds generally agrees with observations. While the code does not include self-gravity, the gravitational stability of the clouds is studied indirectly. It is concluded that clouds in the planetary mass range are stable against gravitational collapse, from supporting thermal pressure alone, when in pressure equilibrium with the heated ionization front. However, gravity may play a significant role during the initial shock compression.

Abstract:
This thesis describes both round-pore microchannel plates (MCPs) used in energetic pho¬ton and particle detectors and their square-pore offspring, micropore optics (MPOs), used to focus x-rays. A Monte Carlo electron raytracing software package is described that is used to predict the energy and angular distribution of electrons (EDOE and ADOE) in a microchannel electron multiplier's output charge cloud, including saturated operation. The model is shown to agree with experimental evidence. The addition of a micromachined electrostatic lens to the end of a microchannel is modelled and found to have no beneficial effects upon the EDOE and ADOE of the channel. The current state of the art planar and slumped 'lobster eye' square-packed MPOs are evaluated. The best focus (5' FWHM) from a large format (61mm x 56mm), small chan¬nel (10μm side length) planar MPO is reported, together with the observation of high energy (~50keV →65keV) x-ray focusing from large (500:1) aspect ratio channels. The alignment of many small lobster eye MPOs to create a large optic for the Lobster-ISS instrument is discussed and the alignment jig constructed for this purpose is used to measure the bias angles of a Lobster specification MPO. The bias angle is found to be 4 ± 1.5'. The concept of the microchannel conic approximation to the Wolter type I and II x- ray lenses is reviewed. A radially-packed twin MPO Wolter approximation is then tested, which while of poor quality, demonstrates true Wolter II imaging with a peak gain greater than unity. Currently proposed (UK) astronomical instruments that employ MPOs are then discussed in the light of the results from the current generation of MPOs.

ENGLISH ABSTRACT: Beamforming is a technique used to combine signals from an array of antennas to effectively synthesize a single aperture and beam. In the Radio Astronomy community the technique is used to obtain a desirable beam pattern as well as to electronically point the beam of an array. Next generation radio telescopes such as the Square Kilometre Array (SKA) surpass current technology and will extensively make use of beamforming techniques. Various factors determine the output of a beamformer; however, given an array with a fixed configuration only the weights applied to the incoming signals affect the synthesized aperture and beam. Furthermore, the incoming data must be processed in real-time, at a rate equal to the input-output rate of the processor. Both the weighting function and the real-time implementation of beamforming, are the primary subjects of this thesis. In this thesis various deterministic weighting functions are investigated. The algorithms are implemented in a matlab program, serving as a simulation tool for investigating the techniques. The program is verified by comparing the expected theoretical outcomes to the simulated output. For the program the following functionalities are included: a steering technique, spectral weighting, Dolph-Chebychev, and the Least Square Error algorithm. Applications of these techniques is investigated and their prominence in the Radio Astronomy community is established. For the real-time beamformer implementation, the UniBoard platform configured with beamformer firmware, is investigated. This is important as the UniBoard is an excellent example of a beamformer implementation within the Radio Astronomy community. The architecture is used to emulate a linear array by implementing a python control script, where the output corresponded accurately with the expected theoretical values. The thesis also constitutes the design and implementation of a digital frequency domain beamformer on the ROACH board. This processing board is employed by the Karoo Array Telescope (KAT-7) in South Africa. This work is therefore important as it demonstrates a beamformer implementation on an architecture in use by the Radio Astronomy community. An antenna array is designed and built for the verification of the beamformer design. Results with a good degree of accuracy were obtained and where errors exist they are discussed.
AFRIKKANSE OPSOMMING: Bundelvorming is ’n tegniek waarmee die seine van ’n antenna samestelling gekombineer word om ’n enkele effektiewe stralingsvlak en stralingspatroon te sintiseer. In die Radio Astronomie gemeenskap word die tegniek gebruik om ’n gewenste stralingspatroon te sintiseer sowel as om die rigting van die patroon elektronies te beheer. Die Square Kilometre Array (SKA) is ’n toekomstige radioteleskoop en sal grootliks gebruik maak van bundelvorming tegnieke. Die uitset van bundelvormers word geaffekteer deur verskeie faktore, maar vir ’n gegewe samestelling is dit net die gewigsfunksies wat toegepas word op die inkomende seine wat die gesintiseerde patroon kan beheer. Verder moet die inkomende data verwerk word teen ’n tempo gelykstaande aan die inset-en-uitsetkoers van die verwerker. Die gewigsfunksie so wel as die implementasie van die bundelvormer is albei primêre onderwerpe van die tesis. ’n Verskeindenheid van deterministiese bundelvormingstegnieke sal ondersoek word in hierdie tesis. Die algoritmes is in ’n matlab program geïmplementeer vir simulasie doeleindes. Die program is geverifieër deur die uitset te vergelyk met die verwagte teoretiese waardes. Die program sluit die volgende funksies in: ’n rigting beheer algoritme, spektraalgewigte, Dolph-Chebychev, en die minste vierkantsfout algoritme. Hierdie tegnieke is van belang weens hul toepassing in die Radio Astronomie gemeenskap. Vir die implementasie van ’n bundelvormer is die UniBoard hardeware, geprogrameer in ’n bundelvormings modus, van gebruik gemaak. Hierdie aspek is belangrik omdat die Uni- Board ’n goeie voorbeeld van ’n geïmplementeerde bundelvormer in die Radio Astronomie gemeenskap is. Die UniBoard word gebruik om ’n lineêre samestelling te emuleer deur in python ’n beheer skrip te skryf, waar die uitset van die emuleerder akkuraat ooreenstem met die verwagte waardes. Die tesis behels ook die ontwerp en implementasie van ’n digitale frekwensiegebied bundelvormer op die ROACH platform. Hierdie verwerker word tans gebruik in die Karoo Array Telescope (KAT-7) in Suid-Afrika. Hierdie werk is dus belangrik omdat dit die implementasie van ’n bundelvormer op tegnologie wat huidiglik in die Radio Astronomie gemeenskap gebruik word demonstreer. Daarbenewens is ’n antenna samestelling ontwerp en gebou om die bundelvormer te verifieër. Die resultate is akkuraat tot ’n redelike mate. Waar daar ’n fout onstaan het word dit in die tesis bespreek.

Abstract:
This thesis investigates photonic spectroscopy and its use in astronomy. In chapter two the theory associated with both astronomical spectroscopy and photonic spectroscopy is shown. The convergence of the two in the field of astrophotonics is discussed along with existing work in the field. In chapter three models of the Integrated Photonic Spectrograph are created and compared like-for-like with existing instruments. The results suggest that the Integrated Photonic Spectrograph will be similar to existing instruments in terms of size and will require more detector pixels for a full instrument. In chapter four the modelling is extended, examining the areas where pho- tonic spectroscopy could show advatanges over conventional instrumentation. This is done by varying spectral resolution, telescope diameter, seeing and num- ber of objects sampled. The results show that the Integrated Photonic Spec- trograph will perform best when the telescope is close to the diffraction-limit, both in terms of size and number of detector pixels required. Science cases are presented for these areas. In chapter five different concepts for a redesigned Integrated Photonic Spec- trograph are presented and the advantages and disadvatanges of the variations are commented upon. The two that are chosen for development require the telescope Point Spread Function to be reformatted to a long slit. This device, which we have named the photonic-dicer is presented in chapter six. Its design, manufacture and testing is discussed both in the laboratory and on sky in conjunction with the CANARY adaptive optics system. Finally chapter seven presents our concluding remarks and discussions for future work.

Abstract:
The search to find answers to the deepest questions we have about the Universe has fueled the collection of data for ever larger volumes of our cosmos. The field of supernova cosmology, for example, is seeing continuous development with upcoming surveys set to produce a vast amount of data that will require new statistical inference and machine learning techniques for processing and analysis. Distinguishing between real objects and artefacts is one of the first steps in any transient science pipeline and, currently, is still carried out by humans - often leading to hand scanners having to sort hundreds or thousands of images per night. This is a time-consuming activity introducing human biases that are extremely hard to characterise. To succeed in the objectives of future transient surveys, the successful substitution of human hand scanners with machine learning techniques for the purpose of this artefact-transient classification therefore represents a vital frontier. In this thesis we test various machine learning algorithms and show that many of them can match the human hand scanner performance in classifying transient difference g, r and i-band imaging data from the SDSS-II SN Survey into real objects and artefacts. Using principal component analysis and linear discriminant analysis, we construct a grand total of 56 feature sets with which to train, optimise and test a Minimum Error Classifier (MEC), a naive Bayes classifier, a k-Nearest Neighbours (kNN) algorithm, a Support Vector Machine (SVM) and the SkyNet artificial neural network.

Abstract:
This thesis is devoted to a study of the origins and achievements of astronomers in Western Australia from 1829 to 1912. It addresses the questions about the role of astronomy in WA society, the reasons for the establishment of the Perth Observatory, and its achievements between 1896 and 1912. More widely, the thesis addresses the general question of the role of astronomy in our society and the contributions which astronomers have made to the development of Western Australia. The first Premier of Western Australia, Sir John Forrest, persuaded his Government to build an Observatory, promising that it would house necessary services for the State, that is, timekeeping, meteorology, geodesy, tidal predictions and education services, to provide a scientific basis for society. This service developed despite continuing opposition and interference from the Government and some sections of society. The thesis assesses the role of Lord Forrest and the Government Astronomer, W.E. Cooke, and his staff. The thesis examines the historical context of the founding of the Observatory, the initial tasks set for it by Cooke and the extent to which these goals were achieved. Cooke's experience in establishing a modern Observatory in a fledgling society is examined in detail in order to understand the reasons for his resignation in 1912 and the nature of his achievements. This study is intended to be both a scientific and social history of astronomy in Western Australia. It examines the scientific achievements of the Perth Observatory over its first 1 6 years in relation to its original objectives. The thesis also examines the social impact of the Observatory on WA society. The extent of its contribution is best assessed in the long-term where the benefits and costs of years of painstaking work can be more clearly understood. This thesis is intended to provide an insight into the role of astronomy in society and the costs and benefits of major scientific institutions. By focussing on the origins and early development of astronomy in WA we can see how the interplay of political, economic and social factors influences the development of science. We can also see how long it takes for scientific projects to reach maturity and how a long-term perspective is required in order to assess their outcomes.

Abstract:
Theodore Metochites (Θεόδωρος Μετοχίτης; 1270–1332), a Byzantine Greek statesman and polymath, and his student, the greatest Byzantine astronomer Nicephoros Gregoras (1295-1360) were in several diplomatic missions on the courts of King Milutin and his son, King Stefan Dečanski. Both gave significant contributions in astronomy. Metochites, considered as the one of the greatest forerunners of the Renaissance in the Greek world, was a Platonist philosopher, astronomer and patron of the arts. From 1305 to 1328 he held the position of personal adviser (mesazon) to emperor Andronikos II Palaiologos. During his long political career he was also Great Logothetes (a kind of Prime Minister) of the Byzantine Empire. His teacher in astronomy was Manuel Bryennius. His known astronomical writting is an introduction to the study of Ptolemaic astronomy (Στοιχείωσις επί τη αστρονομική επιστήμη). Related to astronomy is also his paraphrases of Aristotle's works on natural philosophy and Σημειώσεις γνωμικαί (Annotations), where he provided an important critique of Aristotle. Metochites was five times on the court of King Milutin as the envoy of Andronikos II to make the peace with Serbia and to arrange the mariage of King Milutin with Simonida, grand daughter of the Byzantine emperor. He wrote a writting about his travels to Serbia (Пρεσβευτικός) which is translated to Serbian.

Abstract:
In astrophysics, a significant role is played by observations. During astronomy classes in the absence of surveillance tools interactive programmes such as an interactive programme for space objects simulation can be used as Universe Sandbox2. The aim of this work is to implement interactive programmes for effective astronomy teaching, understanding material and increasing cognitive interest. We observe the evolution of stars while using Universe Sandbox2 during the study of the topic “Evolution of stars”. Using this programme students have an opportunity to get acquainted with the existence of stars with different masses, their differences, to observe changes in the physical characteristics of stars such as: mass, temperature, speed velocity, luminosity, radius and gravity. It will help to develop the ability to analyze, to compare, to form scientific worldview, to develop the attraction for research, to raise the interest for studying astronomy.
