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 $H_0$ 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…
