X-ray behaviour of GRBs detected by INTEGRAL/JEM-X

Abstract

INTEGRAL's JEM-X instrument offers a very rare opportunity to observe the full prompt X-ray emission from GRBs and the transition to the afterglow phase. A study of prompt X-ray flares in some bursts from the INTEGRAL GRB sample and the early X-ray post-GRB emission from 3-35 keV is presented here. Significant post-GRB emission above 10 keV is observed for GRB041219A and GRB081003A. © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike Licence.
