Electromagnetic Signatures from the Tidal Tail of a Black Hole - Neutron Star Merger
Siva Darbha, Daniel Kasen, Francois Foucart +1
Black hole - neutron star (BH-NS) mergers are a major target for ground-based gravitational wave (GW) observatories. A merger can also produce an electromagnetic counterpart (a kil…
Inclination Dependence of Kilonova Light Curves from Globally Aspherical Geometries
Siva Darbha, Daniel Kasen
The merger of two neutron stars (NSs) or a neutron star and a black hole (BH) produces a radioactively-powered transient known as a kilonova, first observed accompanying the gravit…
Ultra-deep tidal disruption events: prompt self-intersections and observables
Siva Darbha, Eric R. Coughlin, Daniel Kasen +1
A star approaching a supermassive black hole (SMBH) can be torn apart in a tidal disruption event (TDE). We examine ultra-deep TDEs, a new regime in which the disrupted debris appr…
Gravitational interactions of stars with supermassive black hole binaries - II. Hypervelocity stars
Siva Darbha, Eric R. Coughlin, Daniel Kasen +1
Supermassive black holes (SMBHs) in galactic nuclei can eject hypervelocity stars (HVSs). Using restricted three-body integrations, we study the properties of stars ejected by circ…
Gravitational interactions of stars with supermassive black hole binaries. I. Tidal disruption events
Siva Darbha, Eric R. Coughlin, Daniel Kasen +1
Stars approaching supermassive black holes (SMBHs) in the centers of galaxies can be torn apart by strong tidal forces. We study the physics of tidal disruption by a binary SMBH as…
Stellar binaries incident on supermassive black hole binaries: implications for double tidal disruption events, calcium-rich transients, and hypervelocity stars
Eric R. Coughlin, Siva Darbha, Daniel Kasen +1
We analyze the outcome of the interaction between a stellar binary and a supermassive black hole binary (SMBHB) by performing a large number of gravitational scattering experiments…
