TL;DR: It is inferred that the primary black hole mass lies within the gap produced by (pulsational) pair-instability supernova processes, with only a 0.32% probability of being below 65 M⊙, which can be considered an intermediate mass black hole (IMBH).

TL;DR: In this article, the authors reported the observation of a compact binary coalescence involving a 22.2 -24.3 magnitude black hole and a compact object with a mass of 2.50 -2.67 magnitude.

TL;DR: In this article, the authors present an up-to-date summary of the rates for all types of compact binary coalescence sources detectable by the Initial and Advanced versions of the ground-based LIGO and Virgo Astrophysical estimates for compact-binary coalescence rates depend on a number of assumptions and unknown model parameters.

TL;DR: In 2019, the LIGO Livingston detector observed a compact binary coalescence with signal-to-noise ratio 12.9 as mentioned in this paper, which is consistent with the individual binary components being neutron stars.
