Importance of relativistic pericenter precession in identifying the presence of a third body near eccentric binaries
Pankaj Saini, Lorenz Zwick, János Takátsy +5
Many astrophysical processes can produce gravitational wave (GW) sources with significant orbital eccentricity. These binaries emit bursts of gravitational radiation during each pe…
Hydrodynamic simulations of black hole evolution in AGN discs I: orbital alignment of highly inclined satellites
Connar Rowan, Henry Whitehead, Gaia Fabj +3
The frequency of compact object interactions in AGN discs is naturally tied to the number of objects embedded within it. We investigate the evolution of black holes in the nuclear…
The construction and use of dephasing prescriptions for environmental effects in gravitational wave astronomy
János Takátsy, Lorenz Zwick, Kai Hendriks +3
In the first part of this work, we provide a curated overview of the theoretical framework necessary for incorporating dephasing due to environmental effects (EE) in gravitational…
Prompt gravitational-wave mergers aided by gas in Active Galactic Nuclei: The hydrodynamics of binary-single black hole scatterings
Connar Rowan, Henry Whitehead, Gaia Fabj +4
Black hole binary systems embedded in AGN discs have been proposed as a source of the observed gravitational waves (GWs) from LIGO-Virgo-KAGRA. Studies have indicated binary-single…
Aligning Nuclear Cluster Orbits with an Active Galactic Nucleus Accretion Disk
Gaia Fabj, Syeda S. Nasim, Freddy Caban +3
Active galactic nuclei (AGN) are powered by the accretion of disks of gas onto supermassive black holes (SMBHs). Stars and stellar remnants orbiting the SMBH in the nuclear star cl…
