16. On Fermi-like neutrino acceleration in core-collapsesupernovae and around black hole formation, andthe evolution of observable neutrino flux duringproto-neutron star collapse
Master-uppsats, Stockholms universitet/Institutionen för astronomiSammanfattning : Failed supernovae are the implosive final fates of massive stars, where ablack hole is formed. During the collapse, the proto-neutron star emits a huge number of neutrinos, and when the black hole is finally formed, it engulfs theneutrino-emitting material and the signal is cut off. LÄS MER
17. Assessment of Modern Statistical Modelling Methods for the Association of High-Energy Neutrinos to Astrophysical Sources
Master-uppsats, KTH/Matematisk statistikSammanfattning : The search for the sources of astrophysical neutrinos is a central open question in particle astrophysics. Thanks to substantial experimental efforts, we now have large-scale neutrino detectors in the oceans and polar ice. LÄS MER
18. Estimating progenitor mass and distance to Galactic Core-Collapse Supernova using neutrino observatory IceCube
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : Galactic core-collapse supernovae is a once-in-a-lifetime event which could carry with it information about new physics. In this work a method for estimating the progenitor mass and distance using the IceCube Neutrino Observatory is presented. The mass is expressed through an intermediate parameter called compactness.

19. Ghosts of Our Past: Neutrino Direction Reconstruction Using Deep Neural Networks
Kandidat-uppsats, Uppsala universitet/HögenergifysikSammanfattning : Neutrinos are the perfect cosmic messengers when it comes to investigating the most violent and mysterious astronomical and cosmological events in the Universe. The interaction probability of neutrinos is small, and the flux of high-energy neutrinos decreases quickly with increasing energy. LÄS MER
20. Sterile Neutrinos and Non-Standard Interactions in Neutrino Telescopes
Master-uppsats, KTH/FysikSammanfattning : The failure of the Standard Model of particle physics to predict neutrino masses invites us to amend it. We have no reason to believe that the interactions currently described by the gauge group are the whole picture, nor should we expect that the number of fermions hitherto observed is correct. LÄS MER
