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…

Partial tidal disruption of White Dwarfs in off-equatorial orbits around Kerr black holes
Aryabrat Mahapatra, Adarsh Pandey, Debojyoti Garain +1
We present the results of a suite of numerical simulations using smoothed particle hydrodynamics to study partial tidal disruption events (TDEs) of white dwarfs (WDs) in off-equato…

Partial tidal disruptions of spinning eccentric white dwarfs by spinning intermediate mass black holes
Debojyoti Garain, Tapobrata Sarkar
Intermediate-mass black holes (IMBHs, ) are often dubbed as the missing link between stellar mass () and super-massive ($\gtrsim 10…
