LIGO AND VIRGO RELEASE NEW RESULTS FROM SEARCHES FOR GRAVITATIONAL WAVES FROM SMALL BLACK HOLES

4 Oct 2021 — In a paper recently submitted to the arXiv, the LIGO and Virgo Collaborations released the results of searches for gravitational waves from the mergers of low-mass black holes. Our paper extends previous analyses in two main ways: we now include data from the Virgo detector and we allow for more unequal mass systems. Our results provide new limits on various astrophysical models (e.g. primordial black holes as dark matter) that could in principle generate the signals that we searched for. The science summary for this paper is also available here.
