Old Data, New Forensics: The First Second of SN 1987A Neutrino Emission
Shirley Weishi Li, John F. Beacom, Luke F. Roberts +1
The next Milky Way supernova will be an epochal event in multi-messenger astronomy, critical to tests of supernovae, neutrinos, and new physics. Realizing this potential depends on…
Fast Neutrino Conversion in Hydrodynamic Simulations of Neutrino-Cooled Accretion Disks
Oliver Just, Sajad Abbar, Meng-Ru Wu +3
The outflows from neutrino-cooled black-hole (BH) accretion disks formed in neutron-star mergers or cores of collapsing stars are expected to be neutron-rich enough to explain a la…
Suppression of Fast Neutrino Flavor Conversions Occurring at Large Distances in Core-Collapse Supernovae
Sajad Abbar, Francesco Capozzi
Neutrinos propagating in dense neutrino media such as core-collapse supernovae and neutron star merger remnants can experience the so-called fast flavor conversions on scales much…
Fast neutrino flavor conversions in one-dimensional core-collapse supernova models with and without muon creation
Francesco Capozzi, Sajad Abbar, Robert Bollig +1
In very dense environments, neutrinos can undergo fast flavor conversions on scales as short as a few centimeters provided that the angular distribution of the neutrino lepton numb…
On the characteristics of fast neutrino flavor instabilities in three-dimensional core-collapse supernova models
Sajad Abbar, Francesco Capozzi, Robert Glas +2
We assess the occurrence of fast neutrino flavor instabilities in two three-dimensional state-of-the-art core-collapse supernova simulations performed using a two-moment three-spec…
Fast Neutrino Flavor Instability in the Neutron-star Convection Layer of Three-dimensional Supernova Models
Robert Glas, H. -Thomas Janka, Francesco Capozzi +4
Neutrinos from a supernova (SN) might undergo fast flavor conversions near the collapsed stellar core. We perform a detailed study of this intriguing possibility, analyzing time-de…
