Researchers propose that LIGO events GW190521, GW190425, and GW190814 may have originated from mirror world binaries, as specific assumptions required to explain these events are more likely in a mirror world scenario where star formation starts earlier and matter density can exceed five times the ordinary matter density.
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 five times the ordinary matter density.
