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.…

Fast flavor instabilities and the search for neutrino angular crossings

Lucas Johns, Hiroki Nagakura

With the recognition that fast flavor instabilities likely affect supernova and neutron-star-merger neutrinos, using simulation data to pin down when and where the instabilities oc…

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…

The Hydrogen Mixing Portal, Its Origins, and Its Cosmological Effects

Lucas Johns, Seth Koren

Hydrogen oscillation into a dark-sector state has recently been proposed as a novel mechanism through which hydrogen can be cooled during the dark ages -- without direct coupl…

Hydrogen Mixing as a Novel Mechanism for Colder Baryons in 21 cm Cosmology

Lucas Johns, Seth Koren

The anomalous 21 cm absorption feature reported by EDGES has galvanized the study of scenarios in which dark matter (DM) siphons off thermal energy from the Standard Model (SM) gas…
