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…
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…
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…
Dynamical Evolution of Quasi-Hierarchical Triples
Yonadav Barry Ginat, Jakob Stegmann, Johan Samsing
We study the gravitational dynamics of quasi-hierarchical triple systems, where the outer orbital period is significantly longer than the inner one, but the outer orbit is extremel…
The Universal Eccentricity Distribution for Dynamical Gravitational-Wave Merger Channels
Mor Rozner, Teagan A. Clarke, Isobel M. Romero-Shaw +1
We argue that all dynamical astrophysical black hole merger channels are expected to result in a common eccentricity distribution at gravitational wave (GW) frequencies relevant fo…
