Evidence of the pair instability gap from black hole masses
Hui Tong, Maya Fishbach, Eric Thrane +13
Stellar theory predicts a forbidden range of black-hole masses between -- due to pair-instability supernovae, but evidence for such a gap in the mass distri…
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…
Implications of low neutron star merger rates for gamma-ray bursts, r-process production and Galactic double neutron stars
Maya Fishbach, Alexander P. Ji, Wen-fai Fong +4
The first multimessenger discovery of a binary neutron star (BNS) merger, GW170817, proved that such mergers can source short gamma-ray bursts (SGRBs) and produce r-process element…
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…
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…
