Mass-gap Black Holes in Coalescing Neutron Star–Black Hole Binaries

Mass-gap Black Holes in Coalescing Neutron Star–Black Hole Binaries

The existence of a mass gap of 3–5 M _⊙ between the heaviest neutron stars (NSs) and the lightest black holes (BHs), inferred from the BH mass distribution in low-mass X-ray binaries (LMXBs), has been suggested for decades. The gravitational-wave (GW) source GW230529 is most likely a neutron star–bl...
