Environmental effects in stellar mass gravitational wave sources II: Enhanced detectability of phase shifts in eccentric sub-populations
Lorenz Zwick, Kai Hendriks, Pankaj Saini +4
We demonstrate that the properties of eccentric gravitational wave (GW) signals enhance the detectability of GW phase shifts caused by environmental effects (EEs): The signal-to-no…
Spin-Orbit Misalignments of Eccentric Black Hole Mergers in AGN Disks
Gaia Fabj, Christopher Tiede, Connar Rowan +2
The disks of active galactic nuclei (AGNs) provide a natural environment where stellar-mass black holes (BHs) can dynamically pair, undergo repeated interactions, and eventually me…
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…
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…
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…
