Abstract:

AbstractWe observed a sample of three Brightest Cluster Galaxies (BCGs), Abell 1836-BCG, Abell 2052-BCG, and Abell 3565-BCG, with the Advanced Camera for Surveys (ACS) and the Imaging Spectrograph (STIS) on board the Space Telescope. For each target galaxy we obtained high-resolution spectroscopy of the Hα and [N II] λ6583 emission lines at three slit positions, to measure the central ionized-gas kinematics. ACS images in three different filters (F435W, F625W, and FR656N) have been used to determine the optical depth of the dust, stellar mass distribution near the nucleus, and intensity map. We present supermassive black hole (SBH) mass estimates for two galaxies which show regular rotation curves and strong central velocity gradients, and an upper limit on the SBH mass of the third one. For the SBHs of Abell 1836-BCG and Abell 3565-BCG, we derived M• = 4.8+0.8−0.7 × 109 M⊙ and M• = 1.3+0.3−0.4 × 109 M⊙ at 1 σ confidence level, respectively. For the SBH of Abell 2052-BCG, we found M• ≤ 7.3 × 109 M⊙.

Abstract:

We report observations of the radio galaxy 3C 317 (at z = 0.0345) located at the center of the Abell cluster A2052, obtained with the VLT/MUSE integral field spectrograph. The Chandra images of this cluster show cavities in the X-ray emitting gas, which were produced by the expansion of the radio lobes inflated by the active galactic nucleus (AGN). Our exquisite MUSE data show with unprecedented detail the complex network of line emitting filaments enshrouding the northern X-ray cavity. We do not detect any emission lines from the southern cavity, with a luminosity asymmetry between the two regions higher than ~75. The emission lines produced by the warm phase of the interstellar medium (WIM) enable us to obtain unique information on the properties of the emitting gas. We find dense gas (up to 270 cm−3) that makes up part of a global quasi spherical outflow that is driven by the radio source, and obtain a direct estimate of the expansion velocity of the cavities (265 km s−1). The emission lines diagnostic rules out ionization from the AGN or from star-forming regions, suggesting instead ionization from slow shocks or from cosmic rays. The striking asymmetric line emission observed between the two cavities contrasts with the less pronounced differences between the north and south sides in the hot gas; this represents a significant new ingredient for our understanding of the process of the exchange of energy between the relativistic plasma and the external medium. We conclude that the expanding radio lobes displace the hot tenuous phase of the interstellar medium (ISM), but also impact the colder and denser ISM phases. These results show the effects of the AGN on its host and the importance of radio mode feedback.

Abstract:

AbstractWe present detailed integral field unit observations of the central few kiloparsecs of the ionized nebulae surrounding four active central cluster galaxies (CCGs) in cooling flow clusters (Abell 0496, 0780, 1644 and 2052). Our sample consists of CCGs with Hα filaments, and have existing data from the X-ray to radio wavelength regimes available, but lacked the detailed optical emission-line (and simultaneous absorption line) data over a broad wavelength range to probe the dominant ionisation processes, excitation sources, morphology and kinematics of the hot gas (as well as the morphology and kinematics of the stars). This, combined with the other multiwavelength data, will form a complete view of the different phases (hot and cold gas and stars) and how they interact in the processes of star formation and feedback detected in central galaxies in cooling flow clusters, as well as the influence of the host cluster. We derive the optical dust extinction maps of the four nebulae. We also derive a range of different kinematic properties, given the small sample size. For Abell 0496 and 0780, we find that the stars and gas are kinematically decoupled, and in the case of Abell 1644 we find that these components are aligned. For Abell 2052, we find that the gaseous components show rotation even though no rotation is apparent in the stellar components. To the degree that our spatial resolution reveals, it appears that all the optical forbidden and hydrogen recombination lines originate in the same gas for all the galaxies. Based on optical diagnostic ratios ([OIII]λ5007/Hβ against [NII]λ6584/Hα, [SII]λ6717,6731/Hα, and [OI]λ6300/Hα), all objects contain a LINER nucleus and show extended LINER-like gas emission. We also show that the hardness of the ionizing continuum does not decrease radially within our field-of-view as the emission line ratios do not vary significantly with radius, thus the derived nebular properties are spatially homogeneous. We fit AGN and pAGB stars photoionisation models as well as shock excitation models to our derived diagnostic ratios. We suggest that AGN photoionisation is the most likely ionisation mechanism even though shocks and pAGB stars can not be conclusively eliminated.

Abstract:

AbstractWe carried out a photometric analysis of a sample of early-type galaxies in Abell~1689 at z = 0.183, using HST/ACS archive images in the rest-frame V band. We performed a two-dimensional photometric decomposition of each galaxy surface-brightness distribution using the GASP2D fitting algorithm (Méndez-Abreu et al. 2008). We adopted both a Sérsic and de Vaucouleurs law. S0 galaxies were analysed also taking into account a disc component described by an exponential law. The derived photometric parameters, together with the ones previously obtained with the curve of growth method (Houghton et al. 2012), will be used to analyse the Fundamental Plane of Abell 1689 and quantify how it is affected by the use of different decomposition techniques (Dalla Bontà et al. 2013, in preparation). The stellar velocity dispersions of the sample galaxies were derived by using GEMINI-N/GMOS and VLT/FLAMES (D'Eugenio et al. 2013) spectroscopic data.

Abstract Shortly after the appearance of the Critique of Pure Reason, Kant’s claim that the ontological proof of God’s existence contains all the probative force of the cosmological argument was discussed at great length by J. F. Flatt, J. F. v. Abel and J. A. Eberhard. These early criticisms do not seem to have received the attention they deserve, even though they are extremely relevant, cogent, and difficult to dispute. Regardless of whether their assumptions are accepted, these objections point out certain obscurities and flaws in Kant’s argument, casting doubt, from a logical standpoint, on the success of the main Kantian criticism of the cosmological proof.

Abstract:

This paper deals with the numerical solution of the Abel integral equation based on Müntz–Legendre wavelets. To this end, the Abel integral operator is represented by Müntz–Legendre wavelets as an operational matrix. To find this matrix, we use the similarity between the Abel integral operator and the fractional integral operator. The proposed method can be easily used to solve weakly singular Volterra integral equations. We have proved the convergence of the proposed method. To demonstrate the ability and accuracy of the method, some numerical examples are presented.

Abstract:

In October, 2001, the Baltimore-based Abell Foundation issued a report purporting to prove that there is "no credible research that supports the use of teacher certification as a regulatory barrier to teaching" and urging the discontinuation of certification in Maryland. The report argued that large inequities in access to certified teachers for poor and minority students are not a problem because research linking teacher education to student achievement is flawed. In July, 2002, the U.S. Secretary of Education cited the Abell Foundation paper in his Annual Report on Teacher Quality as the sole source for concluding that teacher education does not contribute to teacher effectiveness. The Secretary's report then recommended that requirements for education coursework be eliminated from certification standards, and attendance at schools of education and student teaching be made optional. This article documents the many inaccuracies in the Abell Foundation paper and describes the actual findings of many of the studies it purports to review, as well as the findings of other studies it ignores. It details misrepresentations of a number of studies, including inaccurate statements about their methods and findings, false claims about their authors' views, and distortions of their data and conclusions. The article addresses methodological issues regarding the validity and interpretation of research. Finally, the article presents data challenging the Abell Foundation's unfounded claims that uncertified teachers are as effective as certified teachers, that teacher education makes no difference to teacher effectiveness, that verbal ability is the most important determinant of teaching effectiveness, that private schools staffed by uncertified teachers are more effective than public schools, and that untrained teachers are more qualified than prepared teachers. It concludes with a discussion of the policy issues that need to be addressed if all students are to be provided with highly qualified teachers.

Abstract:

Objetiva-se analisar Mateus, protagonista do romance naturalista Amanhã (1901), de Abel Botelho. No final do século XIX, Cesare Lombroso escreve O homem delinquente (1876) e Os anarquistas (1894), em que propõe traçar o perfil de um “delinquente nato”. Em Portugal, Abel Botelho publica a pentalogia intitulada “Patologia Social”, com a qual pretendeu criticar a sociedade portuguesa finissecular, e da qual faz parte Amanhã. Devido ao contexto histórico, sugere-se que Abel Botelho leu as obras de Cesare Lombroso para construir o protagonista de Amanhã. Como procuraremos demonstrar, desde a infância de Mateus, identificamos características que formarão seu caráter de “homem delinquente”.

Alpheus viserion sp. n. is described based on the material from Bocas del Toro archipelago on the Caribbean coast of Panama. The new species is morphologically closest to three members of the speciose A. armillatus H. Milne-Edwards, 1837 species complex, viz. A. carlae Anker, 2012, A. angulosus McClure, 2002, and A. tenuis Kim & Abele, 1988, differing from them, as well as from all the other species currently included in this complex, by a suite of morphological characters and a diagnostic colour pattern. With the description of yet another new shrimp species from Bocas del Toro, the authors hope to contribute to the awareness that this archipelago represents one of the most biologically diverse places in the Caribbean Sea and to encourage the preservation of the remaining natural habitats of this unique area.

Abstract:

Abstract. Radio occultation measurements made with a receiver inside the Earth’s atmosphere can be inverted, assuming local spherical symmetry, with an Abel transform to provide an estimate of the atmospheric refractive index profile. The measurement geometry is closely related to problems encountered when inverting seismic time-travel data and solar occultation measurements, where the Abel solution is well known. The method requires measuring both rays that originate from above and below the local horizon of the receiver. The Abel transform operates on a profile of "partial bending angles" found by subtracting the positive elevation measurement from the negative elevation value with the same impact parameter. In principle, the refractive index profile can be derived from measurements with a single frequency GPS receiver because the ionospheric bending is removed when the partial bending angle is evaluated.Key words.

Abstract:

Abstract The Universal Peace Federation or UPF is a United Nations-affiliated NGO established in 2005 by Mun Sŏn-myŏng (1920–2012), the founder of the South Korean Unification Movement. Mun deemed the UPF’s formation “the most revolutionary and wondrous event since God’s creation of human-kind,” assigning the organisation a pivotal role in his millenarian project. This article continues the discussion in Pokorny and Zoehrer 2022 (which addressed the context, birth, and millenarian anatomy of the UPF), outlining the history of the UPF with a focus on its changing self-conception, leadership shifts, and global activities. It examines how the UPF has articulated and put into practice its millenarian founding ideal over the course of three stages of its development. Finally, it highlights major external and internal challenges, which not only informed the UPF’s identity-building and public perception but render the organisation systemically vulnerable.

Abstract:

The Auditory Behavior in Everyday Life (ABEL) questionnaire was developed to assess parental perceptions of their children's auditory behavior. The original 49-item questionnaire was intended to assess auditory communication, environmental awareness, functional independence, and social/communication skills. Our goal was to capture some of the changes in children's everyday auditory behavior in a reliable and easily quantifiable manner. Parents of 28 children aged 4 to 14 years with varying degrees of hearing loss (mild-profound) completed the questionnaire. The results were used to examine the reliability and factor structure of the questionnaire. Eleven items had poor item-total correlations. After these items were removed, the questionnaire had an overall reliability of 0.94 (Cronbach's alpha), and three factors accounted for 20.5% of the variance in the data. In a pilot investigation of the ABEL to determine its appropriateness for children with cochlear implants, questionnaires were also given to a separate group of parents of seven children aged 3 to 12 years who were about to receive a cochlear implant. Questionnaire and speech perception results were obtained preimplant and at 6, 12, 18, 24, and 36 months. Complete (6 visits) or nearcomplete (4 visits) results were obtained for four children. There were significant improvements over time for both speech perception and questionnaire ratings and there was significant agreement between the two measures. Overall the results indicate excellent reliability and validity of the ABEL questionnaire. Our intent was to develop a simple, quick tool for parents to rate children's auditory skills in everyday life. A shorter questionnaire can be achieved by eliminating items with the poorest reliability and factor loadings. The resultant 24-item ABEL questionnaire has an excellent overall reliability of 0.95. The items fall within three factors, "Aural-oral," "Auditory Awareness," and "Social/Conversational Skills." Children's auditory behavior can be assessed using an overall rating or separately for the three factors. Further research is needed to evaluate this short version of the questionnaire in children wearing hearing aids and cochlear implants.

Abstract:

AbstractThe origin of the morphology-density relation is still an open question in galaxy evolution. It is most likely driven by the combination of the efficient star formation in the highest peaks of the mass distribution at high-z and the transformation by environmental processes at later times as galaxies fall into more massive halos. To gain additional insights about these processes we study the kinematics, star formation and structural properties of galaxies in Abell 2163 a very massive (~4×1015 M⊙, Holz & Perlmutter 2012) merging cluster at z = 0.2.We use high resolution spectroscopy with VLT/VIMOS to derive rotation curves and dynamical masses for galaxies that show regular kinematics. Galaxies that show irregular rotation are also analysed to study the origin of their distortion. This information is combined with stellar masses and structural parameters obtained from high quality CFHT imaging. From narrow band photometry (2.2m/WFI), centered on the redshifted Hα line, we obtain star formation rates.Although our sample is still small, field and cluster galaxies lie in a similar Tully-Fisher relation as local galaxies. Controlling by additional parameters like SFRs or bulge-to-disk ratio do not affect this result. We find however that ~50% of the cluster galaxies display irregular kinematics in contrast to what is found in the field at similar redshifts (~30%, Böhm et al.2004) and in agreement with other studies in clusters (e.g. Bösch et al.2013, Kutdemir et al.2010) which points out to additional processes operating in clusters that distort the galaxy kinematics.

Abstract:

ABSTRACT Radio haloes are extended (∼Mpc), steep spectrum sources found in the central region of dynamically disturbed clusters of galaxies. Only a handful of radio haloes have been reported to reside in galaxy clusters with a mass $M_{500}\lesssim 5\times 10^{14}\, \mathrm{ M}_\odot$. In this paper, we present a LOw Frequency ARray (LOFAR) 144 MHz detection of a radio halo in the galaxy cluster Abell 990 with a mass of $M_{500}=(4.9\pm 0.3)\times 10^{14}\, \mathrm{ M}_\odot$. The halo has a projected size of ${\sim} 700\, {\rm kpc}$ and a flux density of $20.2\pm 2.2\, {\rm mJy}$ or a radio power of $1.2\pm 0.1\times 10^{24}\, {\rm W\, Hz}^{-1}$ at the cluster redshift (z = 0.144) that makes it one of the two haloes with the lowest radio power detected to date. Our analysis of the emission from the cluster with Chandra archival data using dynamical indicators shows that the cluster is not undergoing a major merger but is a slightly disturbed system with a mean temperature of $5\, {\rm keV}$. The low X-ray luminosity of $L_{\mathrm{ X}}=(3.66\pm 0.08)\times 10^{44}\, {\rm erg\, s}^{-1}$ in the 0.1–2.4 keV band implies that the cluster is one of the least luminous systems known to host a radio halo. Our detection of the radio halo in Abell 990 opens the possibility of detecting many more haloes in poorly explored less massive clusters with low-frequency telescopes such as LOFAR, Murchison Widefield Array (MWA, Phase II), and upgraded Giant Metrewave Radio Telescope (uGMRT).

Abstract:

Bošković ( 2005 , 2008 ) outlines a phase-based analysis of adjunct extraction in determinerless languages like Serbo-Croatian (SC). The analysis is modeled on recent phase-based analyses of P(reposition)-stranding (see Abels 2003 , 2012 ) wherein the richness of the functional structure of the PP determines whether extraction is possible. This squib identifies a problem for a unified analysis of these two phenomena. Bans on adjunct extraction are obviated under sluicing while bans on P-stranding are not.

Abstract:

The ( 2 + 1 )-dimensional Lax integrable equation is decomposed into solvable ordinary differential equations with the help of known ( 1 + 1 )-dimensional soliton equations associated with the Ablowitz-Kaup-Newell-Segur soliton hierarchy. Then, based on the finite-order expansion of the Lax matrix, a hyperelliptic Riemann surface and Abel-Jacobi coordinates are introduced to straighten out the associated flows, from which the algebro-geometric solutions of the ( 2 + 1 )-dimensional integrable equation are proposed by means of the Riemann θ functions.

Abstract:

A useful identity relating the infinite sum of two Bessel functions to their infinite integral was discovered in Dominici et al. (Dominici et al. 2012 Proc. R. Soc. A 468 , 2667–2681). Here, we extend this result to products of N Bessel functions, and show it can be straightforwardly proven using the Abel-Plana theorem, or the Poisson summation formula. For N = 2, the proof is much simpler than that of Dominici et al. and significantly enlarges the range of validity.

Abstract:

Abundances of Fe, Si, Ni, Ti, Na, Mg, Cu, Zn, Mn, Cr and Ca in the atmosphere of the K-dwarf HD 77338 are determined and discussed. HD 77338 hosts a hot Uranus-like planet and is currently the most metal-rich single star to host any planet. Determination of abundances was carried out in the framework of a self-consistent approach developed by Pavlenko et al. (2012). Abundances were computed iteratively by the ABEL8 code, and the process converged after 4 iterations. We find that most elements follow the iron abundance, however some of the iron peak elements are found to be over-abundant in this star.

Zusammenfassung: Aus dem Modell des doppelten Einflusses von Geschlecht ( Abele, 2000a , 2002 ) werden Hypothesen zu Geschlecht, geschlechtsbezogenem Selbstkonzept und Berufserfolg abgeleitet und in einer prospektiven Längsschnittstudie (BELA-E) getestet. Hochschulabsolventinnen und -absolventen wurden direkt nach ihrem Examen zu ihrer Geschlechtsrollenorientierung (Instrumentalität und Expressivität) sowie zu ihren auf Geschlechtsrollen bezogenen Einstellungen und 18 Monate später zu ihrem bisherigen Berufserfolg (objektives und subjektives Maß) befragt. Hypothesenkonform sagte die Instrumentalität - nicht jedoch die Expressivität - den Berufserfolg voraus. Ebenfalls hypothesenkonform ist der objektive Berufserfolg von Frauen - und hierbei insbesondere von Müttern - unabhängig von Instrumentalität kleiner als der von Männern. Geschlechtsrolleneinstellungen haben keine Auswirkung auf Berufserfolg. Implikationen für das Modell, für die Berufslaufbahnforschung und für die Geschlechterpsychologie werden diskutiert.

Abstract:

AbstractWe use g and r band imaging from the Palomar Abell Cluster Survey (Gal et al. 2000, AJ 120, 540) in order to estimate internal color gradients, measured as the logarithmic slope of galaxy radial color profiles, for a sample of 4000 early-type galaxies in N = 162 Abell clusters, spanning a wide richness range, from poor groups to rich clusters, and a redshift range of z=0.05 to z=0.25. Color gradients are estimated from the galaxy structural parameters (namely, the effective radius, re, and the Sersic index, n) in the g and r bands. These parameters are derived by fitting galaxy images with 2D PSF convolved Sersic models (La Barbera et al. 2002, ApJ, 571, 790). We select as early-type cluster galaxies those objects with Sersic index n>2, that lie on the color magnitude relation of each cluster. Only objects with S/N ratio high enough to derive reliable structural parameters are included in the analysis (La Barbera et al. 2005, ApJL, 626, 19). Field contamination amounts to ~10%; in our sample and is corrected for by using 32 blank fields observed with the same setup and analyzed in the same way as the cluster images. We find that color gradients follow two distinct redshift trends, with color gradients being less steep for richer rather than poor clusters (La Barbera et al. 2005, ApJL, 626, 19). Fig. 1 plots the mean internal color gradient of galaxies as a function of local galaxy density, which is estimated by using the Voronoi tessellation method. We find that color gradients are strongly dependent on local environment, with color gradients being less steep in higher rather than in lower density regions. However, this environmental trend only holds for poor clusters, with galaxies in rich clusters not showing any significant trend. These results support a picture whereby some interaction mechanism, such as galaxy-galaxy merging, flattens the internal color gradient of galaxies, producing the observed correlation with local density in low richness clusters. If rich clusters form through the merging of groups of galaxies, this process would wash out any correlation between local density and the past merging history of galaxies.

Abstract:

Abstract A commonly recognized feature of the Apocalypse of Moses is its ethical-inferential orientation. However, the present article seeks to show that this does not just manifest itself in retrospective reflection, but is also exemplified narratologically in the attacks on Cain, Abel, and Seth. Far from being superfluous to the main narrative, these incidents provide us with a paradigm for understanding the Apocalypse’s anthropological-hamartiological framework in the post-paradisiacal world: The one who does what is good will send both devil and beast into flight, but the one who does not will be overcome by them. In order to substantiate this thesis, the article compares the Apocalypse to the works of Philo and the Testaments of the Twelve Patriarchs.

AbstractIn the first part, we study the convergence of discrete solutions to splitting schemes for two-phase flow with different mass densities suggested in [Guillen-Gonzalez, Tierra, J.Comput.Math. (6)2014]. They have been formulated for the diffuse interface model in [Abels, Garcke, Grün, M3AS, 2012, DOI:10.1142/S0218202511500138] which is consistent with thermodynamics. Our technique covers various discretization methods for phase-field energies, ranging from convex-concave splitting to difference quotient approaches for the double-well potential. In the second part of the paper, numerical experiments are presented in two space dimensions to identify discretizations of Cahn-Hilliard energies which are ϕ-stable and which do not reduce the acceleration of falling droplets. Finally, 3d simulations in axial symmetric geometries are shown to underline even more the full practicality of the approach.

La metodología seguida fue el análisis de contenido de los objetivos de las PPII y del mencionado perfil, usando la propuesta de Abela (2000). La mayoría de los objetivos apuntan a la gestión técnica de documentos, soslayando el pensamiento crítico, uso de las TIC, ética, trabajo en equipo. Se recomienda ajustar los programas que orientan las PPII considerando como principal criterio las características del profesional que se aspira formar; y establecer mecanismos de monitoreo de los mismos, en aras de hacer las correcciones necesarias.
