Probing the Formation Environment of Strongly Lensed Black Hole Mergers: Implications for the AGN-disk Channel
Johan Samsing, Lorenz Zwick, Pankaj Saini +1
The observation of multiple images from a strongly lensed gravitational wave (GW) source provides the observer with a stereoscopic view of the source. This allows for a measure of…
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…
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…
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…
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…
