Recoil geometry determines electromagnetic counterparts from supermassive black hole merger remnants
Yoonsoo Kim, Elias R. Most, Hai-Yang Wang
Merging binary black holes embedded in gaseous environments, such as supermassive black hole binaries following gas-rich galaxy mergers, are promising sources of multi-messenger tr…

General relativistic magnetized Bondi-Hoyle-Lyttleton accretion with a spin-field misalignment: Jet nutation, polarity reversals, and Magnus drag
Yoonsoo Kim, Elias R. Most
The dynamics of a black hole traveling through a plasma--a general relativistic extension of the classic Bondi-Hoyle-Lyttleton (BHL) accretion problem--can be related to a variety…

Black hole pulsars and monster shocks as outcomes of black hole--neutron star mergers
Yoonsoo Kim, Elias R. Most, Andrei M. Beloborodov +1
The merger of a black hole (BH) and a neutron star (NS) in most cases is expected to leave no material around the remnant BH; therefore, such events are often considered as sources…
