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

Understand

A plateau phase in the X-ray afterglow is observed in a significant fraction of gamma-ray bursts (GRBs).

• Previously, it has been found that there exists a correlation among three key parameters concerning the plateau phase, i.e., the end time of the plateau phase in the GRB rest frame ($T_{a}$), the corresponding X-ray luminosity at the end time ($L_{X}$) and the isotropic energy of the prompt GRB ($E_{\gamma,\rm{iso}}$).
• In this study, we systematically search through all the \emph{Swift} GRBs with a plateau phase that occurred between 2005 May and 2018 August.
• We collect 174 GRBs, with redshifts available for all of them.
