Perturber-Driven Dynamics of Supermassive Black Hole Binaries in Galaxy Merger
Julian Chan, Alessia Gualandris, Walter Dehnen +1
The orbital eccentricity of massive black hole binaries (MBHBs) at binary formation shapes the stochastic gravitational-wave background (GWB) detectable by pulsar timing arrays (PT…

Continuous-Time Modelling of Black Hole Binary Evolution with Neural ODEs
Julian Chan, Alessia Gualandris, Payel Das
Pulsar timing arrays (PTAs) can detect the low-frequency stochastic gravitational-wave background (GWB) generated by an ensemble of supermassive black hole binaries (BHBs). Accurat…

Converging on the eccentricity of massive black hole binaries in galactic mergers
Alessia Gualandris, Justin Read, Federica Fastidio +4
Binaries of supermassive black holes (MBHBs) represent the primary sources of the gravitational wave background (GWB) detectable by Pulsar Timing Arrays (PTAs). The eccentricity wi…
