Monthly Notices of the Royal Astronomical Society, 401: 1369–13740035-8711http://hdl.handle.net/10566/774This 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.en© 2010 copyright Oxford University Press.
