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…
