The cosmological evolution trends of GRB features
Wei, DM ; Gao, WH
AbstractAmati et al. presented the results of spectral and energetic properties of several GRBs with known redshifts. Here we analyse the properties of two groups of GRBs, one group with known redshift from afterglow observation, and another group with redshift derived from the luminosity - variability relation. We study the redshift dependence of various GRBs features in their cosmological rest frames, and find that, for these two group GRB groups, their properties are all redshift dependent, i.e. their intrinsic duration, luminosity, radiated energy and peak energy E (p), are all correlated with the redshift, which means that there are cosmological evolution effects on gamma-ray bursts features, and this can provide an interesting clue to the nature of GRBs.
