Properties of black hole mergers in disks of active galactic nuclei
Hiromichi Tagawa, Zoltán Haiman, Bence Kocsis
Ground-based gravitational wave (GW) observatories have detected approximately 200 binary black hole (BH) mergers. The astrophysical origin of these events are debated, with eviden…
Eccentric Stellar-mass Binary Black Holes: Population, Detectability, and Waveform Analysis in the LISA and LIGO Era
Zeyuan Xuan, Smadar Naoz, Kyle Kremer +3
Eccentric binary black holes (BBHs) formed through dynamical interactions can significantly contribute to gravitational wave (GW) detections. In this work, we present a simulated c…
The Depletion of Collisionless Dark Matter Spikes
Charlie Sharpe, Yonadav Barry Ginat, Thomas F. M. Spieksma +1
Dense concentrations of dark matter (DM) surrounding black holes provide a compelling opportunity to probe the nature of DM. In the classic Gondolo-Silk model, the adiabatic growth…
Black Hole Merger Rates in AGN: contribution from gas-captured binaries
Connar Rowan, Henry Whitehead, Bence Kocsis
It has been suggested that merging black hole (BH) binaries in active galactic nucleus (AGN) discs formed through two-body scatterings via the gas-capture process may explain a sig…
