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…
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…
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…
Including Neutrino-driven Convection into the Force Explosion Condition to Predict Explodability of Multi-dimensional Core-collapse Supernovae (FEC+)
Mariam Gogilashvili, Jeremiah W. Murphy, Jonah M. Miller
Most massive stars end their lives with core collapse. However, it is not clear which explode as a Core-collapse Supernova (CCSN), leaving behind a neutron star and which collapse…
The Force Explosion Condition is Consistent with Spherically Symmetric CCSN Explosions
Mariam Gogilashvili, Jeremiah W. Murphy, Evan P. O'Connor
One of the major challenges in Core-collapse Supernova (CCSN) theory is to predict which stars explode and which collapse to black holes. Gogilashvili and Murphy (2022) derived an…
A Force Explosion Condition for Spherically Symmetric Core-collapse Supernovae
Mariam Gogilashvili, Jeremiah W. Murphy
Understanding which stars explode leaving behind neutron stars and which stars collapse forming black holes remains a fundamental astrophysical problem. We derive an analytic explo…
Explosion Energies for Core-collapse Supernovae I: Analytic, Spherically Symmetric Solutions
Mariam Gogilashvili, Jeremiah W. Murphy, Quintin Mabanta
Recent multi-dimensional simulations of core-collapse supernovae are producing successful explosions and explosion-energy predictions. In general, the explosion-energy evolution is…
Theoretical model of hydrodynamic jet formation from accretion disks with turbulent viscosity
E. Arshilava, M. Gogilashvili, V. Loladze +4
We develop the theoretical model for the analytic description of hydrodynamic jets from protostellar disks employing the Beltrami-Bernoulli flow configuration of disk-jet structure…
