GW200105 and GW200115 are compatible with a scenario of primordial black
  hole binary coalescences
  Two gravitational wave events, i.e. GW200105 and GW200115, were observed by
the Advanced LIGO and Virgo detectors recently. In this work, we show that they
can be explained by a scenario of primordial black hole binaries that are
formed in the early Universe. The merger rate predicted by such a scenario
could be consistent with the one estimated from LIGO and Virgo, even if
primordial black holes constitute a fraction of cold dark matter. The required
abundance of primordial black holes is compatible with the existing upper
limits from microlensing, caustic crossing and cosmic microwave background
observations.
