Up to now several gravitational-wave events from the coalescences of black hole binaries have been reported by LIGO/VIRGO, and imply that black holes should have an extended mass function. We work out the merger rate distribution of primordial black hole (PBH) binaries with a general mass function by taking into account the torques by all PBHs and linear density perturbations. In the future, many more coalescences of black hole binaries are expected to be detected, and the one-dimensional and two-dimensional merger rate distributions will be crucial for reconstructing the mass function of PBHs.

Rates of compact object coalescences (2021, background): “Bird et al. (2016); Ali-Häımoud et al. (2017); Chen and Huang (2018) have argued that a significant fraction of dark matter could be contained in black holes with masses of tens of solar masses, and their mergers could be responsible for some of the gravitational-wave signals observed to date.”
