Effects of magnetically driven shocks on nucleosynthesis and kilonovae from neutron star mergers
Yuan Feng, Oleg Korobkin, Elias R. Most +2
Neutron-star mergers can launch mildly relativistic to moderately relativistic outflows whose interaction with the ejecta can reshape kilonova emission. We parametrically study mag…
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…
A comparison of three neodymium atomic data sets for kilonova modeling
Christopher J. Fontes, Nicholas Vieira, Chris L. Fryer +4
We examine the impact of input neodymium (Nd) atomic data on the light curves and spectra of kilonovae, probing the sensitivity of kilonova observables to the atomic physics of thi…
Joint Electromagnetic and Gravitational Wave Inference of Binary Neutron Star Merger GW170817 Using Forward-Modeling Ejecta Predictions
Marko RistiÄ, Richard O'Shaughnessy, Kate Wagner +5
We reassess the capacity for multimessenger inference of AT2017gfo/GW170817 using both kilonova and gravitational wave emission within the context of a recent simulation-based surr…
Spatial models of r-process remnants and their gamma-ray detectability
Benjamin Amend, Christopher L. Fryer, Matthew R. Mumpower +1
We investigate the detectability of gamma-ray emission from long-lived radioactive isotopes in r-process-enriched remnants, focusing on how assumptions about their spatial distribu…
Inferring neutron star merger ejecta morphologies with kilonovae
Brendan L. King, Soumi De, Oleg Korobkin +2
In this study we incorporate a new grid of kilonova simulations produced by the Monte Carlo radiative transfer code SuperNu in an inference pipeline for astrophysical transients, a…
