LIGO gravitational wave detection, primordial black holes and the near-IR cosmic infrared background anisotropies
@article{Kashlinsky2016LIGOGW, title={LIGO gravitational wave detection, primordial black holes and the near-IR cosmic infrared background anisotropies}, author={A. Kashlinsky}, journal={arXiv: Cosmology and Nongalactic Astrophysics}, year={2016} }
LIGO's discovery of a gravitational wave from two merging black holes (BHs) of similar masses rekindled suggestions that primordial BHs (PBHs) make up the dark matter (DM). If so, PBHs would add a Poissonian isocurvature density fluctuation component to the inflation-produced adiabatic density fluctuations. For LIGO's BH parameters, this extra component would dominate the small-scale power responsible for collapse of early DM halos at z>10, where first luminous sources formed. We quantify the…

It is considered that the black-hole (BH) binary detected by LIGO may be a signature of dark matter, and reasonable estimates span a range that overlaps the 2-53 Gpc^{-3} yr^{-1} rate estimated from GW150914, thus raising the possibility that LigO has detected PBH dark matter.
