摘要
We briefly discuss the most prominent results and specific sources detected by LIGO-Virgo gravitational-wave observatories during the first three O1-O3 runs, as well as possible astrophysical and cosmological channels of their formation. We show that it is possible to explain the observed correlation between the effective spin of coalescing binary black holes and mass ratio of the components by accretion from the ambient medium onto primordial binary black holes. We also briefly discuss the recent results of searches for stochastic gravitational-wave background in the nanohertz frequency band by pulsar timing arrays.
