Binary neutron star mergers with missing electromagnetic counterparts as manifestations of mirror world by Beradze, Revaz, Gogberashvili, Merab, Sakharov, Alexander S.

“…We suggest that the major fraction of binary mergers, which might provide gravitational wave signal detectable by LIGO/VIRGO, emerged from the hidden mirror…”

Unexpected LIGO events and the mirror world by Beradze, Revaz, Gogberashvili, Merab

“…ABSTRACT We consider the possibility that LIGO events GW190521, GW190425, and GW190814 may have emerged from the mirror world binaries. Theories of star…”
