Unexpected LIGO events and the Mirror World
  We consider the possibility that LIGO events GW190521, GW190425 and GW190814
may have emerged from the mirror world binaries. Theories of star evolution
predict so called upper and lower mass gaps and masses of these merger
components lie in that gaps. In order to explain these challenging events very
specific assumptions are required and we argue that such scenarios are order of
magnitude more probable in mirror world, where star formation begins earlier
and matter density can exceed 5 times the ordinary matter density.
