Coalescence Forensics: Weighing the Hosts of Hierarchical Binary Black Hole Mergers
Avinash Tiwari, Shasvath J. Kapadia
We present a novel framework to infer the mass of clusters that host hierarchical binary black hole (BBH) mergers detected with gravitational-waves (GWs), on a single event basis.…

Profiling Dark Matter Spikes with Gravitational Waves from Accelerated Binaries
Avinash Tiwari, Prolay Chanda, Shasvath J. Kapadia +3
Dark matter halos can develop a density spike, e.g., around a galactic supermassive black hole, with the profile determined both by the galaxy's formatio…

Eccentricity evolution consistency test to distinguish eccentric gravitational-wave signals from eccentricity mimickers
Sajad A. Bhat, Avinash Tiwari, Md Arif Shaikh +1
Eccentric compact binary coalescences (CBCs) are expected to be observed in current and future gravitational-wave (GW) detector networks. However, it has been recently pointed out…
