AbstractWe performed a statistical analysis of the intrinsic properties and their redshift dependence of long gamma-ray bursts (GRBs) mainly detected by Swift satellite. The intrinsic quantities are the (z- and K-corrected) rest-frame duration, T (90,rest), the rest-frame peak energy, E (p,rest), the isotropic equivalent energy, E (iso), and the peak isotropic luminosity, L (iso), of the prompt emission. We find that the distributions of T (90,rest), E (p,rest), E (iso) and L (iso) all span a wide range and their central values are T (90,rest)similar to 10 s, E (p,rest)similar to 500 keV, E (iso)similar to 10(53) erg and L (iso similar to)3x10(52) erg/s. We also show that E (p,rest) and L (iso) are independent with T (90,rest), but E (iso) is correlated with T (90,rest). Moreover, we find the observed peak energy is independent with redshift, but the intrinsic peak energy, the isotropic energy and the peak luminosity all show some dependence on redshift, where the truncation effect is taken into account.
