A relativistic jet from a neutron star breaking out of its natal supernova remnant
K. V. S. Gasealahwe, K. Savard, I. M. Monageng +10
The young neutron star X-ray binary, Cir X-1, resides within its natal supernova remnant and experiences ongoing outbursts every 16.5 days, likely due to periastron passage in an e…
Hydrodynamic simulations of black hole evolution in AGN discs II: inclination damping for partially embedded satellites
Henry Whitehead, Connar Rowan, Bence Kocsis
We investigate the evolution of black holes on orbits with small inclinations () to the gaseous discs of active galactic nuclei. We perform 3D adiabatic hydrodynamic s…
Hydrodynamic simulations of black hole evolution in AGN discs I: orbital alignment of highly inclined satellites
Connar Rowan, Henry Whitehead, Gaia Fabj +3
The frequency of compact object interactions in AGN discs is naturally tied to the number of objects embedded within it. We investigate the evolution of black holes in the nuclear…
3D Adiabatic Simulations of Binary Black Hole Formation in AGN
Henry Whitehead, Connar Rowan, Bence Kocsis
We investigate close encounters between initially unbound black holes (BHs) in the gaseous discs of active galactic nuclei (AGN), performing the first 3D non-isothermal hydrodynami…
Prompt gravitational-wave mergers aided by gas in Active Galactic Nuclei: The hydrodynamics of binary-single black hole scatterings
Connar Rowan, Henry Whitehead, Gaia Fabj +4
Black hole binary systems embedded in AGN discs have been proposed as a source of the observed gravitational waves (GWs) from LIGO-Virgo-KAGRA. Studies have indicated binary-single…
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…
