摘要Gamma-ray bursts (GRBs) are luminous enough to be detectable up to redshift z similar to 10. They are often proposed as complementary tools to Type Ia supernovae (SNe Ia) in tracing the Hubble diagram of the Universe. The distance calibrations of GRBs usually make use of one or some of the empirical luminosity correlations, such as iota(lag)-L, V-L, E-p-L, E-p-E-gamma, tau(RT)-L and E-p-E-iso relations. These calibrating methods are based on the underlying assumption that the empirical luminosity correlations are universal over all redshift range. In this paper, we test the possible redshift dependence of six luminosity correlations by dividing GRBs into low-z and high-z classes according to their redshift smaller or larger than 1.4. It is shown that the E-p-E-gamma relation for low-z GRBs is consistent with that for high-z GRBs within 1 sigma uncertainty. The intrinsic scatter of V-L relation is too large to make a convincing conclusion. For the rest four correlations, however, low-z GRBs differ from high-z GRBs at more than 3 sigma confidence level. As such, we calibrate GRBs using the E-p-E-gamma relation in a model-independent way. The constraint of high-z GRBs on the Lambda cold dark matter (Lambda CDM) model gives Omega(M) = 0.302 +/- 0.142(1 sigma), well consistent with the Planck 2015 results.
