1. 1. Exploring Diffuse Supernova Neutrino Background in Hyper-Kamiokande

   University essay from KTH/Fysik

   Author : Klara Cider; [2023]
   Keywords : ;

   Abstract : This thesis studies the Diffuse Supernova Neutrino Background (DSNB) that is expected to be detected in the future neutrino detector Hyper-Hamiokande. DSNB refers to the flux which is made up of neutrinos from all past core-collapsing supernova explosions. READ MORE

3. 2. On Fermi-like neutrino acceleration in core-collapsesupernovae and around black hole formation, andthe evolution of observable neutrino flux duringproto-neutron star collapse

   University essay from Stockholms universitet/Institutionen för astronomi

   Author : Samuel Gullin; [2021]
   Keywords : core collapse black hole neutrino acceleration supernova;

   Abstract : 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. READ MORE

4. 3. Estimating progenitor mass and distance to Galactic Core-Collapse Supernova using neutrino observatory IceCube

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Manne Segerlund; [2021]
   Keywords : Supernova neutrinos; Supernova detection; Multi-messenger astronomy;

   Abstract : 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.

5. 4. Approximating general relativistic effects in Newtonian hydrodynamic supernova simulations

   University essay from Stockholms universitet/Institutionen för astronomi

   Author : Elvira Granqvist; [2019]
   Keywords : ;

   Abstract : In this research, the validity of using an effective potential to approximate general relativistic effects in an otherwise Newtonian setting was investigated, by making simulations of core collapse supernovae on one hand in full general relativity, and on the other hand in said Newtonian setting. This was done for a mass range covering progenitors of 12 − 60 solar masses; a much wider mass range than has been used in earlier research, that also includes progenitors that form black holes.

6. 5. CP-violation in Supernova Neutrino Oscillations

   University essay from Linköpings universitet/Teoretisk Fysik; Linköpings universitet/Tekniska högskolan

   Author : Jessica Elevant; [2014]
   Keywords : CP-violation; δ-phase; neutrino oscillation; three-flavour; supernova;

   Abstract : It is astonishing both how little and how much we know about neutrinos. On one hand, the neutrino is the second most abundant particle in our Universe. Neutrinos may be created in the Sun, core collapse supernovae, cosmic rays, geological background radiation, supernova remnants and in the Big Bang. READ MORE
