英文摘要Using a generalized method, we have tested an estimator of luminosity/redshift proposed by Zhang et al. (2006a), in which relative spectral lag (RSL) is tightly related with luminosity and redshift, respectively. The derived luminosities from the new estimator are found to be comparable with the observed ones. For two different GRB samples, we have examined that there are no outliers violated the luminosity relation within 3 sigma confidence level. Several potential outliers for other luminosity relations are otherwise found to match the estimator well. These results suggest that the luminosity/redshift relation could be a potential tool for cosmological studies.
