Outflows in steep density gradients: diversity of behavior and implications for tidal disruption events and luminous fast blue optical transients
Benjamin Amend, Michael Camilo, Eric R. Coughlin +2
Powerful explosions may undergo sustained energy injection as a central engine launches a wind into the surrounding gas, generating a forward and a reverse shock separated by a con…
The interaction phase of engine-driven explosions and high-energy winds
Benjamin Amend, Christopher Lagomarsino, Eric R. Coughlin +1
Wide-angle outflows, or winds, are associated with a broad range of astrophysical systems, including protostars, massive stars, X-ray binaries, tidal disruption events (TDEs), lumi…
The Role of Stellar Spin in Repeating Partial Tidal Disruption Events
Ananya Bandopadhyay, Benjamin Amend, Eric R. Coughlin +3
The repeated tidal stripping of a star by a supermassive black hole, known as a repeating partial tidal disruption event (rpTDE), can give rise to a transient that rebrightens mont…
Systematic Error in Approximate Models of the GRB Early Afterglow
Benjamin Amend, Eric R. Coughlin, Jonathan Zrake
Gamma-ray burst (GRB) afterglows are thought to arise when relativistic ejecta launched by a compact central engine drive a blast wave into the surrounding circumburst medium, prod…
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…
