Gravitational Wave Phase shifts of black hole mergers in AGN Disks
Hiromichi Tagawa, Connar Rowan, János Takátsy +4
Ground-based gravitational wave (GW) detectors have discovered about 200 compact object mergers. The astrophysical origins of these events are highly debated, and it is possible th…
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 II: inclination damping for partially embedded satellites
Henry Whitehead, Connar Rowan, Bence Kocsis
We investigate the evolution of black holes on orbits with small inclinations () to the gaseous discs of active galactic nuclei. We perform 3D adiabatic hydrodynamic s…
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…
Gas meets Kozai: the influence of a gas-rich accretion disc on hierarchical triples undergoing von Zeipel-Lidov-Kozai oscillations
Yubo Su, Connar Rowan, Mor Rozner
Active galactic nuclei (AGNs) consist of a central supermassive black hole (SMBH) embedded in a region with both high gas and stellar densities: the gas is present as a thin accret…
Environmental effects in stellar mass gravitational wave sources I: Expected fraction of signals with significant dephasing in the dynamical and AGN channels
Lorenz Zwick, János Takátsy, Pankaj Saini +5
We present the first overview of the expected quantity of signals which will showcase significant gravitational wave phase shifts caused by astrophysical environments, considering…
