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…
Large Gravitational Wave Phase Shifts from Strong 3-body Interactions in Dense Stellar Clusters
Kai Hendriks, Dany Atallah, Miguel Martinez +7
The phase evolution of gravitational waves (GWs) can be modulated by the astrophysical environment surrounding the source, which provides a probe for the origin of individual binar…
Towards gravitational wave parameter inference for binaries with an eccentric companion
Kai Hendriks, Lorenz Zwick, Pankaj Saini +2
We introduce a complete model for dephasing due to line-of-sight acceleration (LOSA) in gravitational wave (GW) signals from stellar-mass binary black holes (BBHs) in three-body sy…
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…
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…
