Hubble constant measurement with 13 bright standard sirens from binary black hole mergers inside active galactic nuclei
Dhruv Kumar, Alejandro Torres-Orjuela
We measure the Hubble constant using 13 gravitational-wave binary black hole mergers associated with active galactic nucleus hosts. We find $H_0=70.50^{+3.37}_{-2.89}\,({\rm…

A population of LIGO-Virgo-KAGRA mergers happening inside active galactic nuclei
Dhruv Kumar, Alejandro Torres-Orjuela
Multimessenger observations of compact binary mergers in active galactic nuclei (AGN) offer unique probes of black hole formation channels and cosmology. We analyse 18 gravitationa…

Accelerating parameter estimation for parameterized tests of general relativity with gravitational-wave observations
Dhruv Kumar, Ish Gupta, Bangalore Sathyaprakash
Tests of general relativity (GR) with gravitational waves (GWs) introduce additional deviation parameters in the waveform model. The enlarged parameter space makes inference comput…
