Irreducible relic abundance of vortons
Vortons are centrifugally supported cosmic string loops that can be continuously created at all times during the cosmological expansion. Could they be all of the dark matter?

The gravitational waves emitted during the merging of two black holes of 85 and 66 times the sun mass have been detected on May 25, 2019 by the LIGO detectors in the United States and the Virgo detector in Italy.
More …Two candidate mergers of primordial black holes from the QCD epoch
The two recent gravitational-wave events GW190425 and GW190814 from the third observing run of LIGO/Virgo have both a companion which is unexpected if originated from a neutron star or a stellar black hole. Sébastien and Juan García-Bellido investigate the possibility that these objects are Primordial Black Holes (PBHs) in Ref. [1].
