Investigating the Precursor and Prompt Emission of Swift Gamma-Ray Bursts (GRBs)
Abstract
We analyze the spectral lag, i.e. the arrival offset of high and low energy photons, for both the precursor and prompt emission of Swift-BAT GRBs, to probe if the precursor emission is an early activation of the progenitor's central engine activity.
