Dynamic Competition of Fast and Collisional Neutrino Flavor Instabilities with Collisional Damping in Spatially Inhomogeneous Systems
Shota Takahashi, Hiroki Nagakura, Masamichi Zaizen +2
Neutrino flavor evolution in dense astrophysical environments such as core-collapse supernova (CCSN) is influenced by collective effects. While the Fast Flavor Instability (FFI) an…
Comprehensive neutrino light curves and spectra: from pre-supernova evolution to early supernova phase
Chinami Kato, Hiroki Nagakura, Akira Ito +4
We present the first systematic study of neutrino emissions from massive stars, continuously tracking the late evolutionary stages through the early core-collapse supernova phase.…
Inspecting neutrino flavor instabilities during proto-neutron star cooling phase in supernova: I. Spherically symmetric model
Masamichi Zaizen, Sherwood Richers, Hiroki Nagakura +2
In the standard model of core-collapse supernova (CCSN), all neutrinos are assumed to be in pure flavor eigenstates in CCSN cores, but the assumption becomes invalid if neutrino di…
Collisional flavor swap with neutrino self-interactions
Chinami Kato, Hiroki Nagakura, Lucas Johns
Neutrinos play pivotal roles in determining fluid dynamics, nucleosynthesis, and their observables in core-collapse supernova (CCSN) and binary neutron star merger (BNSM). In this…
Flavor conversions with energy-dependent neutrino emission and absorption
Chinami Kato, Hiroki Nagakura, Masamichi Zaizen
Fast neutrino flavor conversions (FFCs) and collisional flavor instabilities (CFIs) potentially affect the dynamics of core-collapse supernovae (CCSNe) and binary neutron star merg…
Effects of energy-dependent scatterings on fast neutrino flavor conversions
Chinami Kato, Hiroki Nagakura
Neutrino self-interactions in a dense neutrino gas can induce collective neutrino flavor conversions. Fast neutrino flavor conversions (FFCs), one of the collective neutrino conver…
