Abstract:
AbstractWe investigate the lowest mass stars that produce Type-II supernovae, motivated by recent results showing that a large fraction of type-II supernova progenitors for which there are direct detections display unexpectedly low luminosity (for a review see e.g. Smartt 2009). There are three potential evolutionary channels leading to this fate. Alongside the standard ‘massive star’ Fe-core collapse scenario we investigate the likelihood of electron capture supernovae (EC-SNe) from super-AGB (S-AGB) stars in their thermal pulse phase, from failed massive stars for which neon burning and other advanced burning stages fail to prevent the star from contracting to the critical densities required to initiate rapid electron-capture reactions and thus the star's collapse. We find it indeed possible that both of these relatively exotic evolutionary channels may be realised but it is currently unclear for what proportion of stars. Ultimately, the supernova light curves, explosion energies, remnant properties (see e.g. Knigge et al. 2011) and ejecta composition are the quantities desired to establish the role that these stars at the lower edge of the massive star mass range play.

Abstract:
Les explosions gamma (GRB) sont des évènements extrêmement violents. Ils sont sommairement classifiés en deux groupes par leur durée : les courts et les longs. Cette classification a permis de déterminer l'origine des GRBs : une collision entre deux objets compacts pour les courts ou l'explosion d'une étoile très massive pour les longs. Une meilleure classification des GRBs longs pourrait mieux contraindre leurs propriétés. Dans ma thèse, je présente des évidences de l'existence d'une sous-classification des GRBs basés sur la faible luminosité de leurs derniers reflets. Ces explosions sont appelées Low-Luminosity Afterflow (LLA). Je présente la technique de réduction des données, la méthode de sélection de ces GRBs ainsi que leurs principales propriétés. Leur lien avec les supernovæ (SN) est mis en évidence car 64 % de tous les GRBs associés à des Sns sont des LLA GRBs. Finalement, je présente d'autres propriétés comme leur fréquence, qui semble indiquer une nouvelle distincte classe, les propriétés de leurs galaxies hôte qui montrent que ces explosions ont pour origines des galaxies formant beaucoup d'étoiles. De plus, je montre qu'il est difficile de réconcilier les différences entre les GRBs normaux et les LLA GRBs en ne considérant que des effets instrumentaux et environnementaux, ou bien une géométrie différente. Donc je conclue que les deux classes de GRBs ont des propriétés différentes. En basant l'argumentation sur la fonction de masse initiale, sur la fréquence des LLA GRBs et sur le type de SNs qui les accompagnent, j'indique qu'un système binaire est favorisé pour leur origine<br>Gamma-ray bursts (GRB) are extreme events. They are crudely classified into two groups based on their duration, namely the short and long bursts. Such a classification has proven to be useful to determine their progenitors: the merger of two compact objects for short bursts and the explosion of a massive star for long bursts. Further classifying the long GRBs might give tighter constraints on their progenitor and on the emission mechanism(s). In my thesis, I present evidence for the existence of a sub-class of long GRBs, based on their faint afterglow emission. These bursts were named low-luminosity afterglow (LLA) GRBs. I discuss the data analysis and the selection method, and their main properties are described. Their link to supernova is strong as 64\% of all the bursts firmly associated to SNe is LLA GRBs. Finally, I present additional properties of LLA GRBs: the study of their rate density, which seems to indicate a new distinct third class of events, the properties of their host galaxies, which show that they take place in young star-forming galaxies. Additionally, I show that it is difficult to reconcile all differences between normal long GRBs and LLA GRBs only by considering instrumental or environmental effects, different ejecta content or a different geometry for the burst. Thus, I conclude that LLA GRBs and normal long GRBs should have different properties. In a very rudimentary discussion, I indicate that a binary system is favored in the case of LLA GRB. The argument is based on the initial mass function of massive stars, on the larger rate density of LLA GRBs compared to the rate of normal long GRBs and on the type of accompanying SNe

Abstract:
abstract: For this project, the diffuse supernova neutrino background (DSNB) has been calculated based on the recent direct supernova rate measurements and neutrino spectrum from SN1987A. The estimated diffuse electron antineutrino flux is &sim; 0.10 &ndash; 0.59 /cm2/s at 99% confidence level, which is 5 times lower than the Super-Kamiokande 2012 upper limit of 3.0 /cm2/s, above energy threshold of 17.3 MeV. With a Megaton scale water detector, 40 events could be detected above the threshold per year. In addition, the detectability of neutrino bursts from direct black hole forming collapses (failed supernovae) at Megaton detectors is calculated. These neutrino bursts are energetic and with short time duration, &sim; 1s. They could be identified by the time coincidence of N &ge;2 or N &ge;3 events within 1s time window from nearby (4 &ndash; 5 Mpc) failed supernovae. The detection rate of these neutrino bursts could get up to one per decade. This is a realistic way to detect a failed supernova and gives a promising method for studying the physics of direct black hole formation mechanism. Finally, the absorption of ultra high energy (UHE) neutrinos by the cosmic neutrino background, with full inclusion of the effect of the thermal distribution of the background on the resonant annihilation channel, is discussed. Results are applied to serval models of UHE neutrino sources. Suppression effects are strong for sources that extend beyond z &sim; 10. This provides a fascinating probe of the physics of the relic neutrino background in the unexplored redshift interval z &sim; 10 &ndash; 100. Ultimately this research will examine the detectability of DSNB, neutrino bursts from failed supernovae and absorption effects in the neutrino spectrum.<br>Dissertation/Thesis<br>Ph.D. Physics 2013

Abstract:
Physicists began to believe in black holes when research revealed new information about the constitution of stars and their life cycles, indicating that a black hole represents the death of certain massive stars. Chandrasekhar used quantum mechanics and the notion of a degenerate electron gas to obtain the maximum mass of a white dwarf. A degenerate neutron gas produced enough pressure to stop the gravitational collapse of a massive star, producing a neutron star or pulsar. For a massive-enough star, the degenerate neutron gas fails to prevent gravitational collapse into a black hole. Supernovae explosions and implosions produce a neutron star or black hole as remnants. Oppenheimer and Volkoff used general relativity to derive the maximum mass of a star that would produce a black hole. Wheeler conceived of a “hairless black hole” in which only the mass, charge, and angular momentum determined the properties of the black hole.
