We study high-energy neutrino production in collimated jets inside blue supergiant (BSG) progenitors of gamma-ray bursts (GRBs). Assuming
ultralong GRBs, cosmic ray acceleration and neutrino production at the point where collimation begins, we use a semi-analytic approach to
calculate the neutrino injection spectrum. These are then propagated through simulations, taking into account...

We simulate the collapse of a rotating core of the progenitor with 11.2 solar mass with the Boltzmann-radiation-hydrodynamics code, which solves the Boltzmann equations for neutrino transfer directly. We pay particular attention to the neutrino distribution in phase space, which is affected by the rotation. By solving the Boltzmann equations directly, we can assess the rotation-induced...

A proto-neutron star (PNS) is a newly formed compact object in a core collapse supernova. Using a series of phenomenological equations of state (EOS), we have systematically investigated the neutrino emission from the cooling process of a PNS. The numerical code utilized in this study follows a quasi-static evolution of a PNS solving the general-relativistic stellar structure with neutrino...

Neutrino flavor evolution in dense neutrino media is a very nonlinear and rich phenomenon. Such dense neutrino media could be found in, but not limited to, core-collapse supernovae (CCSNe). It is of great importance to study neutrino flavor oscillations in CCSNe due to its important consequences for the matter composition, the SN dynamics and also for the observed neutrino spectra on earth. In...
