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…
Suppressed accretion onto massive black hole binaries surrounded by thin disks
Christopher Tiede, Jonathan Zrake, Andrew MacFadyen +1
We demonstrate that gas disks around binary systems might deliver gas to the binary components only when the circumbinary disk is relatively warm. We present new grid-based hydrody…
Thermal X-ray signatures in late-stage unequal-mass massive black hole binary mergers
Luke Major Krauth, Jordy Davelaar, Zoltán Haiman +3
The multi-messenger combination of gravitational waves (GWs) from merging massive black hole binaries (MBHBs) and the electromagnetic (EM) counterpart from the surrounding circumbi…
Gravitational Wave Decoupling in Retrograde Circumbinary Disks
David O'Neill, Christopher Tiede, Daniel J. D'Orazio +2
We present a study of the late-time interaction between supermassive black hole binaries and retrograde circumbinary disks during the period of gravitational wave-driven inspiral.…
