Abstract
This paper presents a study of the relation between gamma-ray burster redshift and several
of its prompt emission properties (spectral lag, light curve variability, peak energy, rise time
and the peak bolometric flux Pbol). Simple predictors of log(1 + z) in terms of Pbol and the
other indicators are derived. The typical scatter in the relations is 0.13 dex. An illustrative
application to observations of GRB 090423 (z ∼ 8) is given.
