Full textL'utilisation d'un calorimètre segmenté longitudinalement et transversalement permet de mesurer l'énergie et la position des gerbes avec une bonne précision, malgré sa faible épaisseur. A partir de simulations et de tests sur faisceau, nous avons mis au point des méthodes de reconstruction adaptées aux divers domaines d'énergie et d'angle d'incidence : correction des pertes dans la matière passive du trajectographe, correction de fuites longitudinale, et ajustement de profil de gerbe. Les performances obtenues sont détaillées. Nous détaillons aussi la mesure de position dans un calorimètre segmenté et mettons en évidence un certain nombre de biais de mesure.
D'autre part, la forte augmentation du nombre de sources attendues et la possibilité d'observer des objets étendus motivent la mise au point de méthodes d'analyse plus efficaces que celles à base de maximum de vraisemblance utilisées actuellement. Nous proposons une méthode fondée sur l'analyse en ondelettes adaptée à la recherche de source sur un fond brillant et hautement structuré. La statistique des tranformées en ondelettes du fond est détaillée. La méthode a été testée sur les données d'EGRET et nous discutons son application à GLAST.
Enfin, nous proposons et discutons l'utilisation de GLAST comme télescope à électrons cosmiques de très haute énergie (de quelques centaines de GeV à quelques TeV). Nous discutons en particulier les implications d'une telle mesure vis-à-vis de la production d'électrons dans les restes de supernovae proches et de leur propagation dans le milieu interstellaire. Plusieurs modèles d'accélérations ont été envisagés au sein des restes connus au voisinage du Soleil.

Full textSVOM is a Chinese-French astronomy mission due to launch at the end of 2021 for the study of Gamma-Ray Bursts (GRBs). SVOM will be composed of a network of ground telescopes along with a satellite. On board, the Micro-channel X-ray Telescope (MXT) will study the afterglow emission of GRBs in the 0.2-10 keV range and provide source localization within a 2 arcmin precision. At the focal plane of lobster-eye optics, MXT will mount a back-illuminated fully-depleted frame-store Charge Coupled Device based on silicon pn-junctions (pnCCD), heritage of XMM-Newton and eROSITA. In this work, the first laboratory tests on the MXT detector are presented. Special attention is dedicated to energy calibration, in terms of algorithms and setups for fast and reliable characterization of the detector, both on ground and in orbit. The evolution of the performance is of critical concern because of the harsh radiation environment of the low Earth orbit to which the detector will be exposed. This is the object of extensive Monte Carlo simulations, leading to predictions of the end-of-life performances as well as the planning of a proton irradiation campaign at a particle accelerator for the experimental validation of the predictions

Full textThis study is devoted to solar like oscillations, i. E. Excited by turbulent convection in the outer convective zone of the star. Rotation affects the fine structure of the frequency spectrum by lifting. A degeneracy similary as the Zeeman effect. Ln the first, I study how rotational pattern in the spectrum is affected by the magnetic field using a 9 years data set of solar observations by GOLF on board the SOHO spacecraft. I have intented to show the differential response of the modes to the magnetic field depending on their spatial structure at the surface. After testing the method of measure on artificial data, I showed that there is a variation of the multiplet asymetry with the frequency at solar low activity and that this pattern vanishes at higher activity. Moreover in the future one should use in parallel spatially resolved observations of the solar disk. The second part is dedicated to the seismology of other solar like stars, and more precisely on the international rotation of such objects. Using numerical stellar models, I could show that the po or diversity of available modes does not prevent to partially infer the rotation profile along the radius for such sorne specific stars. Constraints on the mass age and surface velocity of such potential targets in the frame of the COROT mission are given. Eventually, stars with surface rotating 10 times faster than the sun are not uncommon. The frequency spectrum of such rotators is strongly affected by non-linear effects and near degeneracy between close models. I could show that in such cases these effects should no longer be neglected should be taken into account to properly understand the spectrum and to model such objets

Full textDiscovered in the early 1970s, gamma-ray bursts (GRBs) are amazing cosmic phenomena appearing randomly on the sky and releasing large amounts of energy mainly through gamma-ray emission. Although their origin is still under debate, they are believed to be produced by some of the most violent explosions in the Universe leading to the formation of stellar black-holes. GRBs are detected by their prompt emission, an intense short burst of gamma-rays (from a few millisecondes to few minutes), and are followed by a lived-afterglow emission observed on longer timescales from the X-ray to the radio domain. My thesis participates to the developement of the SVOM mission, which a Chinese-French mission to be launched in 2021, devoted to the study of GRBs and involving space and ground instruments. My work is focussed on the main instrument ECLAIRs, a hard X-ray coded mask imaging camera, in charge of the near real-time detection and localization of the prompt emission of GRBs. During my thesis, I studied the scientific performances of ECLAIRs and in particular the number of GRBs expected to be detected by ECLAIRs and their characteristics. For this purpose, I performed simulations using the prototypes of the embedded trigger algorithms combined with the model of the ECLAIRs instrument. The input data of the simulations include a background model and a synthetic population of gamma-ray bursts generated from existing catalogs (CGRO, HETE-2, Fermi and Swift). As a result, I estimated precisely the ECLAIRs detection efficiency of the algorithms and I predicted the number of GRBs to be detected by ECLAIRs : 40 to 70 GRBs per year. Moreover, the study highlighted that ECLAIRs will be particularly sensitive to the X-ray rich GRB population. My thesis provided additional studies about the localization performance, the rate of false alarm and the characteristics of the triggers of the algorithms. Finally, I also proposed two new methods for the detection of GRBs.The preliminary results were very promising and demonstrate that the sensitivity of ECLAIRs to the short GRBs (an interesting population due to the predicted association with gravitational waves) could be improved further
