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…
Massive Perturbers and Transient Pickup Discs in Disc-Crossing Encounters in OJ 287-like Supermassive Black Hole Binaries
Debojyoti Garain, Jonathan Zrake, Zoltan Haiman
We study the hydrodynamical response of a massive black hole accretion disc punctured by a lower mass black hole on an inclined, eccentric orbit, as motivated by the quasi-periodic…
Stochastic Variability of Binary Accretion
Akhil Nair, Jonathan Zrake
We measure the power spectral density (PSD) of the accretion rate time series in an unequal mass (q = 0.2) binary surrounded by a circumbinary gas disk, using very high-resolution…
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…
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…
Eccentric Disks from Gaseous Rings around Equal-Mass, Circular Binaries
Leonardo Betancourt, Andrew MacFadyen, Jonathan Zrake
We perform high-resolution, grid-based hydrodynamics simulations of gaseous rings viscously spreading into disks around equal-mass, circular binaries. We find that all systems supp…
