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…
Dynamics of Relativistic Binaries in Structured and Stochastic Environments: A Lagrange-Fourier-Hansen Framework
Lorenz Zwick, Conor Dyson, Brian C. Seymour +2
We develop a general framework to characterize non-vacuum perturbations to relativistic binaries in the gravitational-wave (GW) driven regime, for use in GW parameter estimation st…
Amplified capture rate of dark matter in compact binaries and constraints on bosonic dark matter from GW170817
János Takátsy, Lorenz Zwick, David O'Neill +1
The accretion of dark matter (DM) onto compact objects and the potential gravitational collapse of neutron stars due to this accretion has become a promising indirect probe of DM p…
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…
Dissecting environmental effects with eccentric gravitational wave sources
Lorenz Zwick, Kai Hendriks, David O'Neill +6
We model the effect of resonances between time-varying perturbative forces and the epi-cyclical motion of eccentric binaries in the gravitational wave (GW) driven regime. These ind…
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…
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…
Large Gravitational Wave Phase Shifts from Strong 3-body Interactions in Dense Stellar Clusters
Kai Hendriks, Dany Atallah, Miguel Martinez +6
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…
Eccentricity distributions of eccentric binary black holes in galactic nuclei
János Takátsy, Bence Bécsy, Peter Raffai
Galactic nuclei are expected to be one of the main sites for formations of eccentric binary black holes (EBBHs), with an estimated detection rate of yr…
