Abstract
Light curves of 115 bright gamma-ray bursts with known cosmological distances z from sources detected by the BAT telescope on board the Swift spacecraft in four energy channels are analyzed. An averaged curve describing the shift of the light curves is obtained that depends on the energy of the channels in the coordinate system associated with the source. The results are compared to similar detailed curves for individual gamma-ray bursts detected in a wider range of energies by the BATSE (CGRO) and GBM (FERMI) telescopes. The divergence of curves in the region of low energies for some gamma ray bursts indicates the existence of an additional radiation source.
