Abstract
Primordial black holes are one possible formation channel for the binary black holes observed by LIGO-Virgo-Kagra. The authors perform a data analysis of the O3 events to infer stringent constraint on the primordial black hole abundance in a wide mass range. Furthermore, they show that this result is robust with respect to astrophysical modeling.
