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…

Thermal Radiation Transport with Tensor Trains

Alex A. Gorodetsky, Patrick D. Mullen, Aditya Deshpande +4

We present a novel tensor network algorithm to solve the time-dependent, gray thermal radiation transport equation. The method invokes a tensor train (TT) decomposition for the spe…

Not-Quite-Transcendental Functions For Logarithmic Interpolation of Tabulated Data

Peter C. Hammond, Jacob M. Fields, Jonah M. Miller +1

From tabulated nuclear and degenerate equations of state to photon and neutrino opacities, to nuclear reaction rates: tabulated data is ubiquitous in computational astrophysics. Th…

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…
