Neutrino flavor instabilities intermediate between slow and fast
Nicolas Viaux, Lucas Johns
The neutrino flavor composition in supernovae and neutron star mergers is shaped by flavor instabilities, which are commonly classified into three types: slow (SFI), fast (FFI), an…
An Analytic Threshold for LESA-Driven Negative ELN Flux Directions in Core-Collapse Supernovae: Derivation and Population Census
Nicolás Viaux, Lucas Johns
In core-collapse supernovae (CCSNe), deleptonization normally favors over emission. However, lepton-number emission self-sustained asymmetry (LESA) can make the ene…
Testing common approximations of neutrino fast flavor conversion
Erick Urquilla, Lucas Johns
A new chapter is opening in the theory of core-collapse supernovae and neutron star mergers as simulations of these events begin to incorporate fast flavor conversion (FFC) and oth…
Neutrino Oscillations in Core-Collapse Supernovae and Neutron Star Mergers
Lucas Johns, Sherwood Richers, Meng-Ru Wu
Accurate neutrino transport is crucial for reliably modeling explosive astrophysical events like core-collapse supernovae (CCSNe) and neutron star mergers (NSMs). However, in these…
Subgrid modeling of neutrino oscillations in astrophysics
Lucas Johns
Approximating neutrino oscillations as subgrid physics is an appealing prospect for simulators of core-collapse supernovae and neutron-star mergers. Because flavor instabilities qu…
