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…
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…
Turbulence Fingerprint on Collective Oscillations of Supernova Neutrinos
Sajad Abbar
We bring to light a novel mechanism through which turbulent matter density fluctuations can induce collective neutrino flavor conversions in core-collapse supernovae, i.e., the lea…
Collective Oscillations of Majorana Neutrinos in Strong Magnetic Fields and Self-induced Flavor Equilibrium
Sajad Abbar
We study collective oscillations of Majorana neutrinos in some of the most extreme astrophysical sites such as neutron star merger remnants and magneto-rotational core-collapse sup…
Fast Neutrino Flavor Conversion Modes in Multidimensional Core-collapse Supernova Models: the Role of the Asymmetric Neutrino Distributions
Sajad Abbar, Huaiyu Duan, Kohsuke Sumiyoshi +2
A dense neutrino gas, such as the one anticipated in the supernova environment, can experience fast neutrino flavor conversions on scales much shorter than those expected in vacuum…
