The maximum mass ratio of hierarchical binary black hole mergers may cause the - correlation
Aditya Vijaykumar, Amanda M. Farah, Maya Fishbach
Regardless of their initial spins, the merger of two roughly equal mass black holes (BHs) produces a remnant BH of dimensionless spin . Such remnants can merge with other BHs…

The steep redshift evolution of the hierarchical binary black hole merger rate may cause the - correlation
Amanda M. Farah, Aditya Vijaykumar, Maya Fishbach
There is growing evidence from gravitational-wave observations that some merging black holes are created from previous mergers. Using the prediction that these hierarchically merge…

How Low Can You Go: Constraining the Effects of Catalog Incompleteness on Dark Siren Cosmology
Madison VanWyngarden, Maya Fishbach, Aditya Vijaykumar +2
Gravitational waves (GWs) serve as standard sirens by directly encoding the luminosity distance to their source. When the host galaxy redshift is known, for example, through observ…
