 要:Primordial black holes (PBHs) as a viable candidate of dark matter (DM) can explain the gravitational wave (GW) events detected by LIGO. I will demonstrate how to measure the abundance of PBHs by using the stochastic gravitational wave backgrounds (SGWBs) from PBH binary coalescences and enhanced scalar perturbations, respectively. Meanwhile, I will show that the angular power spectrum for the anisotropies in SGWB can be a new observational window to probe PBHs in the future.
