A. Martin-Carrillo, L. Hanlon (University College Dublin)
TL;DR
This paper analyzes the prompt X-ray emission and early afterglow phase of GRBs detected by INTEGRAL/JEM-X, revealing significant post-GRB emission above 10 keV in specific cases.
Contribution
It presents new observations of prompt X-ray flares and early post-GRB emission in the 3-35 keV range using INTEGRAL/JEM-X, highlighting rare high-energy post-GRB signals.
Findings
Detection of significant post-GRB emission above 10 keV for GRB 041219A.
Observation of prompt X-ray flares in the INTEGRAL GRB sample.
Insights into the transition from prompt emission to afterglow phase.
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 GRB 041219A and GRB 081003A.
