Nonthermal filaments from the tidal destruction of clouds in the Galactic center
Eric R. Coughlin, C. J. Nixon, Adam Ginsburg
Synchrotron-emitting, nonthermal filaments (NTFs) have been observed near the Galactic center for nearly four decades, yet their physical origin remains unclear. Here we investigat…
The Influence of Black Hole Binarity on Tidal Disruption Events
Eric R. Coughlin, Philip J. Armitage, Giuseppe Lodato +1
Mergers are fundamental to the standard paradigm of galaxy evolution, and provide a natural formation mechanism for supermassive black hole binaries. The formation process of such…
Partial Stellar Disruption by a Supermassive Black Hole: Is the Lightcurve Really Proportional to ?
Eric R. Coughlin, C. J. Nixon
The tidal disruption of a star by a supermassive black hole, and the subsequent accretion of the disrupted debris by that black hole, offers a direct means to study the inner regio…
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…
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…
Circumbinary discs from tidal disruption events
Eric R. Coughlin, Philip J. Armitage
Tidal disruption events, which occur when a star is shredded by the tidal field of a supermassive black hole, provide a means of fueling black hole accretion. Here we show, using a…
