Disc Novae: Thermodynamics of Gas Assisted Binary Black Hole Formation in AGN Discs
Henry Whitehead, Connar Rowan, Tjarda Boekholt +1
We investigate the thermodynamics of close encounters between stellar mass black holes (BHs) in the gaseous discs of active galactic nuclei (AGN), during which binary black holes (…
Detecting Gravitational Wave Bursts From Stellar-Mass Binaries in the Milli-hertz Band
Zeyuan Xuan, Smadar Naoz, Bence Kocsis +1
The dynamical formation channels of gravitational wave (GW) sources typically involve a stage when the compact object binary source interacts with the environment, which may excite…
Black Hole Binaries in AGN Accretion Discs II: Gas Effects on Black Hole Satellite Scatterings
Connar Rowan, Henry Whitehead, Tjarda Boekholt +2
The black hole (BH) binaries in active galactic nuclei (AGN) are expected to form mainly through scattering encounters in the ambient gaseous medium. Recent simulations, including…
Gas Assisted Binary Black Hole Formation in AGN Discs
Henry Whitehead, Connar Rowan, Tjarda Boekholt +1
We investigate close encounters by stellar mass black holes (BHs) in the gaseous discs of active galactic nuclei (AGN) as a potential formation channel of binary black holes (BBHs)…
Quiescent and active galactic nuclei as factories of merging compact objects in the era of gravitational-wave astronomy
Manuel Arca Sedda, Smadar Naoz, Bence Kocsis
Galactic nuclei harbouring a central supermassive black hole (SMBH), possibly surrounded by a dense nuclear cluster (NC), represent extreme environments which house a complex inter…
Anisotropic mass segregation: two-component mean-field model
Hanxi Wang, Bence Kocsis
Galactic nuclei, the densest stellar environments in the Universe, exhibit a complex geometrical structure. The stars orbiting the central supermassive black hole follow a mass seg…
