@article{AliHaimoud2017MergerRO, title={Merger rate of primordial black-hole binaries}, author={Yacine Ali-Haimoud and Ely D. Kovetz and Marc Kamionkowski Nyu and Jhu}, journal={Physical Review D}, year={2017}, volume={96}, pages={123523} }
Primordial black holes (PBHs) have long been a candidate for the elusive dark matter (DM), and remain poorly constrained in the ~20-100 Msun mass range. PBH binaries were recently suggested as the possible source of LIGO's first detections. In this paper, we thoroughly revisit existing estimates of the merger rate of PBH binaries. We compute the probability distribution of orbital parameters for PBH binaries formed in the early Universe, accounting for tidal torquing by all other PBHs, as well…
