Evolution of collisional neutrino flavor instabilities in spherically symmetric supernova models
Zewei Xiong, Meng-Ru Wu, Gabriel Martínez-Pinedo +4
We implement a multi-group and discrete-ordinate neutrino transport model in spherical symmetry which allows to simulate collective neutrino oscillations by including realistic col…
Where, when and why: occurrence of fast-pairwise collective neutrino oscillation in three-dimensional core-collapse supernova models
Hiroki Nagakura, Lucas Johns, Adam Burrows +1
Fast-pairwise collective neutrino oscillation represents a key uncertainty in the theory of core-collapse supernova (CCSN). Despite the potentially significant impact on CCSN dynam…
New method for detecting fast neutrino flavor conversions in core-collapse supernova models with two-moment neutrino transport
Hiroki Nagakura, Lucas Johns
Fast-pairwise neutrino oscillations potentially affect many aspects of core-collapse supernova (CCSN): the explosion mechanism, neutrino signals, and nucleosynthesis in the ejecta.…
Constructing angular distributions of neutrinos in core collapse supernova from zero-th and first moments calibrated by full Boltzmann neutrino transport
Hiroki Nagakura, Lucas Johns
Two-moment neutrino transport methods have been widely used for developing theoretical models of core-collapse supernova (CCSN), since they substantially reduce the computational b…
Catching Element Formation In The Act
Chris L. Fryer, Frank Timmes, Aimee L. Hungerford +216
Gamma-ray astronomy explores the most energetic photons in nature to address some of the most pressing puzzles in contemporary astrophysics. It encompasses a wide range of objects…
An optimization-based approach to calculating neutrino flavor evolution
Eve Armstrong, Amol V. Patwardhan, Lucas Johns +3
We assess the utility of an optimization-based data assimilation (D.A.) technique for treating the problem of nonlinear neutrino flavor transformation in core collapse supernovae.…
