A parametrized test of general relativity for inspiralling eccentric binaries in LISA
Pankaj Saini, Sylvain Marsat, Lorenz Zwick +2
The space-based detector Laser Interferometer Space Antenna (LISA) will observe inspiralling black hole binaries in the mHz band, many of which may retain orbital eccentricity. In…
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…
Orbital eccentricity can make neutron star g-mode resonances observable with current gravitational-wave detectors
János Takátsy, Lorenz Zwick, Pankaj Saini +1
Dynamical tides can provide us vital information about the properties of neutron star (NS) matter. This is particularly true for g-modes, whose frequency and tidal coupling are hig…
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…
