Cosmology with gamma-ray bursts - I. The Hubble diagram through the calibrated Ep,i–Eiso correlation
Context. Gamma-ray bursts (GRBs) are the most energetics explosions in the Universe. They are detectable up to very high redshifts. They may therefore be used to study the expansion rate of the Universe and to investigate the observational properties of dark energy, provided that empirical correlations between spectral and intensity …
