Statistical Study of Gamma-Ray Bursts with a Plateau Phase in the X-Ray Afterglow

A plateau phase in the X-ray afterglow is observed in a significant fraction of gamma-ray bursts (GRBs). Previously, a correlation among three key parameters concerning the plateau phase is found to exist, i.e., the end time of the plateau phase in the GRB rest frame (Ta), the corresponding X-ray luminosity at the end time (LX) and the isotropic energy of the prompt GRB (Eγ,iso). In this study, we systematically search through all the Swift GRBs...
