Impact of calibration uncertainties on Hubble constant measurements from gravitational-wave sources
Yiwen Huang, Hsin-Yu Chen, Carl-Johan Haster +3
Gravitational-wave (GW) detections of electromagnetically bright compact binary coalescences can provide an independent measurement of the Hubble constant . In order to obtain…
The binary black hole spin distribution likely broadens with redshift
Sylvia Biscoveanu, Thomas A. Callister, Carl-Johan Haster +3
The population-level distributions of the masses, spins, and redshifts of binary black holes (BBHs) observed using gravitational waves can shed light on how these systems form and…
Targeted large mass ratio numerical relativity surrogate waveform model for GW190814
Jooheon Yoo, Vijay Varma, Matthew Giesler +5
Gravitational wave observations of large mass ratio compact binary mergers like GW190814 highlight the need for reliable, high-accuracy waveform templates for such systems. We pres…
Evidence of large recoil velocity from a black hole merger signal
Vijay Varma, Sylvia Biscoveanu, Tousif Islam +6
The final black hole left behind after a binary black hole merger can attain a recoil velocity, or a "kick", reaching values up to 5000 km/s. This phenomenon has important implicat…
