Abstract

      We present a review of possible cosmological applications of Gamma-Ray-Bursts multi-wavelength observations. A statistical analysis of the main pulse parameters of BeppoSAX, BATSE, Fermi and Swift GRB observational data is conducted. The spatial distribution of GRB sources with known redshifts is analyzed. Selection effects that distort the true source distribution are taken into account by comparing the observed distribution with fractal and uniform model catalogs. We review GRBs as standard candles and test of Universe isotropy by GRBs. We approximated trend of cosmological time dilation by long GRBs and discuss in detail possible effects that influence their statistics.
