Flavor Conversion Enhances or Suppresses Supernova Explodability Independent of the Progenitor Mass
Mariam Gogilashvili, Irene Tamborra
Flavor conversion can affect the neutrino-driven delayed explosion mechanism of collapsing massive stars, altering the efficiency of shock revival. We perform core-collapse superno…
Neutrino Flavor Conversion Shapes the Rate of Failed Core-collapse Supernovae
Mariam Gogilashvili, Irene Tamborra
The relative rate of neutron stars and black holes produced by the collapse of massive stars is highly uncertain. We simulate the stellar collapse of progenitors with masses…
Robustness of Solutions of the Quantum Kinetic Equations in the Presence of Matter Density Fluctuations
Shashank Shalgar, Mariam Gogilashvili
We investigate the role of fluctuations in the matter density on neutrino flavor evolution by studying their effects on the collision terms in the spherically symmetric quantum kin…
Quantifying the Impact of the Si/O Interface in CCSN Explosions Using the Force Explosion Condition
Luca Boccioli, Mariam Gogilashvili, Jeremiah Murphy +1
The explosion mechanism of a core-collapse supernova is a complex interplay between neutrino heating and cooling (including the effects of neutrino-driven convection), the gravitat…
Phoebus: Performance Portable GRRMHD for Relativistic Astrophysics
Brandon Barker, Mariam Gogilashvili, Janiris Rodriguez-Bueno +6
We introduce the open source code PHOEBUS (phifty one ergs blows up a star) for astrophysical general relativistic radiation magnetohydrodynamic simulations. PHOEBUS is designed fo…
