A Magnetic Unification of Merging Supermassive Black Hole Binaries
Mark J. Avara, David O'Neill, Zoltán Haiman
The detection of an electromagnetic (EM) transient from a supermassive black hole binary (SMBHB) merging within a gaseous environment will constitute a multi-messenger milestone. N…
Electromagnetic Emission and Orbital Evolution of Eccentric Supermassive Black Hole Binaries in Retrograde Disks
David ONeill, Mark J. Avara, Christopher Tiede +3
Circumbinary disks around supermassive black hole binaries (SMBHBs) are expected to form across a broad range of inclinations, with retrograde configurations potentially a common o…
Gaseous Dynamical Friction on Hyperbolic Scatterings
David O'Neill, Daniel J. D'Orazio, Martin E. Pessah
We present a study of equal-mass hyperbolic encounters, embedded in a uniform gaseous medium. Using linear perturbation theory, we calculate the density wakes excited by these pert…
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.…
Gaseous Dynamical Friction on Elliptical Keplerian Orbits
David O'Neill, Daniel J. D'Orazio, Johan Samsing +1
We compute the Gaseous Dynamical Friction (GDF) force experienced by massive perturbers on elliptical Keplerian orbits. In this paper, we investigate the density wake morphology, d…
