Abstract

      We represent a review of the short GRBs classification problem. We took four largest GRBs catalogs: BATSE, BeppoSAX, Swift and Fermi and, as a first approximation, constructed duration distributions for short GRBs, that is GRBs shorter than 2 seconds. It turned out that on 0.1, 0.2 and 1 seconds we have statistical peaks which we associate with different types of binary mergers. The multimessenger astronomy allows us to come closer to a binary mergers analysis by gravitational-wave observations. Also we offer a new test for existence of event horizon through it.
