Повний текст джерелаCosmic rays, with an energy density of ∼ 1eVcm–3, play an important role in the evolution of our Galaxy. Very high energy (TeV) gamma rays provide unique information about the acceleration sites of Galactic cosmic rays. The High Altitude Water Cherenkov (HAWC) Gamma-Ray Observatory is an all-sky surveying instrument sensitive to gamma rays from 100,GeV to 100,TeV with a 2steradian instantaneous field of view and a duty cycle of >95%. The array is located in Sierra Negra, Mexico at an elevation of 4,100m and was inaugurated in March 2015. Thanks to its modular design, science operation began in Summer 2013 with one third of the array. Using this data, a survey of the inner Galaxy region of Galactic longitude l ∈ [+15°, +50°] and latitude b ∈ [–4°, +4°] is performed. To address the ambiguities arising from unresolved sources in the data, a maximum likelihood technique is used to identify point source candidates. Ten sources and candidate sources are identified in this analysis. Eight of these are associated with known TeV sources but not all have differential fluxes compatible with previous measurements. Three sources are detected with significances >5σ after accounting for statistical trials, and are associated with known TeV sources. With data taken with the full array and improved reconstruction algorithms, the significance on the Crab nebula increases from 3.1σ√day to 5.5σ√day, which allows more sensitive sky surveys and more precise spectral and morphological analyses on individual sources.

Повний текст джерелаmeasurements of the 1.809 MeV gamma-ray line arising from the decay of
radioactive 26Al.
The COMPTEL telescope aboard the Compton Gamma-Ray Observatory, launched on
April 5, 1991, permits for the first time an extensive investigation of the
1.8 MeV radiation throughout the entire sky.
The aim of this thesis is to infer the galactic distribution of 26Al from
these measurements and to identify the dominant sources of this
radioactive isotope.
The first part of the thesis is dedicated to the reconstruction of
the 1.8 MeV intensity distribution from the measured data.
It is demonstrated that the use of conventional deconvolution
algorithms, like maximum likelihood or maximum entropy inversion,
leads to lumpy, noise-dominated intensity distributions.
Nevertheless, simulations can help to assess the uncertainties in the
reconstructed images, which permits the scientific exploitation of the
recovered skymaps.
Alternatively, a multiresolution approach is proposed, which largely
reduces the uncertainties in the reconstructed 1.8 MeV intensity
distribution.
In summary, 1.8 MeV emission is mainly concentrated towards the
galactic plane, which clearly demonstrates that the bulk of 26Al is of
galactic rather than local origin.
However, distinct emission features towards Cygnus, Carina, and the
Auriga-Camelopardalis-Perseus region are inconsistent with a smooth
galactic 1.8 MeV emission profile, pointing towards a massive star
origin of 26Al.
The second part of the thesis consists of a multi-wavelength
comparison of COMPTEL 1.8 MeV data which aims in the
identification of the origin of galactic 26Al.
For the comparison, a rigorous Bayesian analysis is applied, which
is the only consistent framework that allows inference based on the
comparison.
It turned out that the 1.8 MeV distribution follows very closely
the distribution of free electrons in the Galaxy which is traced by
thermal bremsstrahlung, observable in the microwave domain.
The similarity of the 1.8 MeV intensity distribution to the
thermal bremsstrahlung distribution implies a direct proportionality
between the 26Al and the massive star column densities, which strongly
supports that massive stars are the origin of galactic 26Al.
In particular, ONeMg-novae and AGB stars can be excluded as dominant
26Al sources since their galactic distribution is not expected to
correlate with the distribution of free electrons.
The correlation between 26Al and free electrons established, the
analysis of 1.8 MeV gamma-ray line emission can complement our knowledge
about star formation and the distribution of ionized gas throughout
the entire Galaxy.
While COMPTEL made the first step in providing the first all-sky map
in the light of the 1.809 MeV line, INTEGRAL, the next generation gamma-ray spectrometer, will allow a detailed study of current star formation
in the Galaxy.

Повний текст джерелаLes binàries de raigs gamma són sistemes binaries formats per una estrella jove i massiva i un objecte compacte, que pot ser un púlsar jove o un forat negre, que emeten radiació fins a desenes de TeV i mostren variabilitat orbital en totes les bandes d'emissió, des de radio fins a raigs gamma. En el cas de tres de les quatre binàries de raigs gamma detectades avui dia, se'n desconeix la natura de l'objecte compacte. En aquesta tesi presentem un estudi de les binàries de raigs gamma mitjançant tres treballs complementaris que involucren l'estudi simultani d'aquestes fonts en raigs X i raigs gamma de molt alta energia. En primer lloc presentem el descobriment d'emissió en raigs X i raigs gamma de molt alta energia correlades en el temps al sistema LS I +61 303. Aquesta correlació ens indica que l'emissió en les dues bandes pot provenir d'una única població d'electrons, i ho confirmem mitjançant la realització d'un model teòric de radiació que ens permet restringir significativament les propietats físiques de l'emissor no tèrmic de la font. En cas que la font energètica dels sistemes sigui un púlsar, la interacció entre els vents de l'estrella i el púlsar dona lloc a una regió d'interacció on el vent xocat del púlsar accelera partícules i emet des de radio fins a raigs gamma. A l'espectre de raigs X, però, no es detecta l'emissió tèrmica del vent xocat de l'estrella, que s'escalfa fins a desenes de milers de graus. Això ens ha permès estudiar la forma de la regió d'interacció, determinada principalment per la potència del púlsar, i fer un càlcul teòric de l'emissió en raigs X tèrmics. Hem aplicat aquest model al sistema LS 5039 i hem pogut determinar la potència del púlsar, fet important per a la modelització de l'emissió no tèrmica de la font. Finalment, presentem la cerca d'emissió de raigs gamma provinent de sistemes binaris fins ara no detectats. Una campanya simultània en raigs X i raigs gamma ens va permetre seleccionar les dades de molt alta energia del microquàsar Sco X-1 en funció de l'estat d'acreció sobre l'objecte compacte. Tot i no detectar la font en raigs gamma, els límits superiors obtinguts permeten restringir les propietats físiques de Sco X-1 rellevants per a l'emissió en molt alta energia.
