Physics-based phenomenological modeling of binary black hole hierarchical formation 2: Autodifferentiable functional inference of hierarchical compact-binary populations
R. O'Shaughnessy, M. Zeeshan, M. Qazalbash
The gravitational-wave (GW) census contains mass and spin structure consistent with contributions from black holes assembled through repeated mergers in dense environments. Connect…
Physics-based phenomenological modeling of binary black hole hierarchical formation 1: Synthetic universes from globular cluster simulations for GWTC
R. O'Shaughnessy, R. Mechum, M. Qazalbash +2
We iteratively model the GWTC-5.0 binary-black-hole census with three components. First, a physically normalized population from Rapster globular-cluster simulations spans cluster…
Narrow Population Inference Enhanced by Analytical Likelihood Models
Meesum Qazalbash, Sophiya Mehra, Muhammad Zeeshan +2
The growing catalog of gravitational-wave events has revealed substantial diversity in the properties of compact-binary mergers. However, commonly used population-inference methods…
An Implementation to Identify the Properties of Multiple Population of Gravitational Wave Sources
Meesum Qazalbash, Muhammad Zeeshan, Richard O'Shaughnessy
The rapidly increasing sensitivity of gravitational wave detectors is enabling the detection of a growing number of compact binary mergers. These events are crucial for understandi…
