Kilonovae and Long-duration Gamma-ray Bursts
Marko RistiÄ, 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…
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…
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…
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…
