On the Evolution of Disk-Embedded Binaries: Framing Local Models in Global Context
Philip Kirkeberg, Rixin Li, Martin E. Pessah
The disks of Active Galactic Nuclei (AGN) have in recent years been recognized as possible sites for gravitational wave sources, leading to a series of numerical studies on the evo…
Dissecting environmental effects with eccentric gravitational wave sources
Lorenz Zwick, Kai Hendriks, David O'Neill +6
We model the effect of resonances between time-varying perturbative forces and the epi-cyclical motion of eccentric binaries in the gravitational wave (GW) driven regime. These ind…
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…
Gravitational Wave Memory Imprints on the CMB from Populations of Massive Black Hole Mergers
Lorenz Zwick, David O'Neill, Kai Hendriks +2
Aims: To showcase and characterise the rich phenomenology of temperature fluctuation patterns that are imprinted on the CMB by the gravitational wave memory (GWM) of massive black…
