Possibility of primordial black holes as the source of gravitational wave events in the advanced LIGO detector

The analysis of gravitational Wave (GW) data from advanced LIGO provides the mass each companion binary black holes as source GWs. events corresponding to GW is above $20$ M$_\odot$ which much larger than astrophysical detected by x-ray observations. In this work, we examine primordial (PBHs) events. Assuming that $100\%$ dark matter made PBHs, estimate rate at these objects make binaries, merge, and produce GWs a function redshift. lensing PBHs can also enhance amplitude strain. We simulate sourced with detection threshold $S/N>10$ for both Livingston Hanford detectors. For log-normal generate expected distribution events, compare our results observed find best value parameters (i.e., $M_c =25 M_\odot$ $\sigma=0.6$) in function. Comparing number ones rules out present-Universe formation PBH scenario candidate LIGO.
