Quantifying the evidence against a mass gap between black holes and neutron stars
The lack of objects between and in the joint
mass distribution of compact objects has been termed "mass gap", and attributed
mainly to the characteristics of the supernova mechanism precluding their
birth. However, recent observations show that a number of candidates reported
to lie inside the "gap" may fill it, suggesting instead a paucity that may be
real or largely a result of small number statistics. We quantify in this work
the individual candidates and evaluate the joint probability of a mass gap. Our
results show that an absolute mass gap is not present, to a very high
confidence level. It remains to be seen if a relative paucity of objects stands
in the future, and how this population can be related to the formation
processes, which may include neutron star mergers, collapse of a neutron star
to a black hole and others.Comment: 20 pages, 7 figures, 5 tables. Accepted for publication in Ap
