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

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 GRB 041219A and GRB 081003A.
