Neutrino masses and mixings produce vacuum oscillations, an established quantum
mechanical phenomenon. In matter, the Mikheev-Smirnov-Wolfenstein effect, due to …

Neutrinos are known to play important roles in many astrophysical scenarios from the early
period of the big bang to current stellar evolution being a unique messenger of the fusion …

We explore the impact of small-scale flavor conversions of neutrinos, the so-called fast flavor
conversions (FFCs), on the dynamical evolution and neutrino emission of core-collapse …

One of the greatest uncertainties in any modeling of the inner engine of core-collapse
supernova (CCSN) is neutrino-flavor conversions driven by neutrino self-interactions. We …

The fast flavor conversions (FFCs) of neutrinos generally exist in core-collapse supernovae
and binary neutron-star merger remnants and can significantly change the flavor …

Neutrino-neutrino forward scatterings potentially induce collective neutrino oscillation in
dense neutrino gases in astrophysical sites such as core-collapse supernovae (CCSNe) …

We implement a multigroup and discrete-ordinate neutrino transport model in spherical
symmetry which allows to simulate collective neutrino oscillations by including realistic …

By performing general relativistic hydrodynamics simulations with an approximate neutrino
radiation transfer, the properties of ejecta in the dynamical and post-merger phases are …

The question of what ingredients characterize the quasisteady state of fast neutrino-flavor
conversion (FFC) is one of the longstanding riddles in neutrino oscillation. Addressing this …

Despite the theoretical indication that fast neutrino-flavor conversion (FFC) ubiquitously
occurs iin core-collapse supernovae and binary neutron star mergers, the lack of global …
