Description
The energy emission involved in a Gamma-Ray Burst evidently can be
estimated only provided that we know the distance to the source. The
same is true for the peak energy of the event in the source rest frame.
Redshifts have been actually measured only for about 40 events. In order
to check if it is possible to extend the Epeakrest E relation
originally found by Amati et al. [Intrinsic spectra and energetics of
BeppoSAX Gamma-Ray Bursts with known redshifts. Astron. Astrophys. 390,
81 89, 2002] to a larger number of events, we make use of the
pseudo-redshift estimate proposed by Atteia [A simple empirical redshift
indicator for Gamma-Ray Bursts. Astron. Astrophys. 407, L1 L4, 2003] and
of the spectra published by Band et al. [BATSE observations of Gamma-Ray
Burst spectra: I. Spectral diversity, ApJ 413, 281 292, 1993]. We thus
obtain a completely independent set of events which indeed follows the
same Epeakrest E relation and confirms it.
