An Observational Upper Limit on the Rate of Gamma-Ray Bursts with Neutron Star-Black Hole Merger Progenitors
Abstract
Compact-object binary mergers consisting of one neutron star and one black hole (NSBHs) have long been considered promising progenitors for gamma-ray bursts, whose central engine remains poorly understood. Using gravitational-wave constraints on the population-level NSBH mass and spin distributions we find that at most 20 Gpc-3 yr-1 of gamma-ray bursts in the local universe can have NSBH progenitors.
