Kilonovae and Long-duration Gamma-ray Bursts
Marko Ristić, Brandon L. Barker, Samuel Cupp +5
Recent detections of kilonova-like emission following long-duration gamma-ray bursts GRB211211A and GRB230307A have been interpreted as originating from the merger of two neutron s…
Let there be neutrons! Hadronic photoproduction from a large flux of high-energy photons
Matthew R. Mumpower, Tsung-Shung H. Lee, Nicole Lloyd-Ronning +4
We propose that neutrons may be generated in high-energy, high-flux photon environments via photo-induced reactions on pre-existing baryons. These photohadronic interactions are ex…
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…
Kilonova Emissions from Neutron Star Merger Remnants: Implications for Nuclear Equation of State
Kelsey A. Lund, Rahul Somasundaram, Gail C. McLaughlin +3
Multi-messenger observation of binary neutron-star mergers can provide valuable information on the nuclear equation of state (EoS). Here, we investigate to which extent electromagn…
The time evolution of fast flavor crossings in post-merger disks around a black hole remnant
Payel Mukhopadhyay, Jonah Miller, Gail C. McLaughlin
We postprocess a three-dimensional general relativistic, full transport neutrino radiation magnetohydrodynamics simulation of the black hole--accretion disk--wind system thought to…
Magnetic Field Strength Effects on Nucleosynthesis from Neutron Star Merger Outflows
Kelsey Alexandra Lund, Gail McLaughlin, Jonah Miller +1
Magnetohydrodynamic turbulence drives the central engine of post-merger remnants, potentially powering both a nucleosynthetically active disk wind and the relativistic jet behind a…
The Effect of the Velocity Distribution on Kilonova Emission
Chris L. Fryer, Aimee L. Hungerford, Ryan T. Wollaeger +7
The electromagnetic emission from the non-relativistic ejecta launched in neutron star mergers (either dynamically or through a disk wind) has the potential to probe both the total…
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…
Emergent nucleosynthesis from a 1.2 second long simulation of a black-hole accretion disk
T. M. Sprouse, K. A. Lund, J. M. Miller +2
We simulate a black-hole accretion disk system with full-transport general relativistic neutrino radiation magnetohydrodynamics (GRRMHD) for 1.2 seconds. This system is likely t…
The Dependence of Gamma-Ray Burst Jet Collimation on Black Hole Spin
Valeria U. Hurtado, Nicole M. Lloyd-Ronning, Jonah M. Miller
Gamma-Ray Bursts are the most luminous events in the Universe, and are excellent laboratories to study extreme physical phenomena in the cosmos. Despite a long trajectory of progre…
