X-ray Analysis of Gamma-Ray Burst Flares and Underlying Afterglows: Insights into Origin of Flares
H. Dereli-Bégué, A. Pe'er, D. Bégué +2
Gamma-ray burst (GRB) X-ray light curves exhibit a variety of complex temporal structures, such as flares and plateaus. The origin of flares seen in many GRB early afterglows is st…

Gamma-ray burst pulse structures and emission mechanisms
A Gowri, A. Pe'er, F. Ryde +1
The prompt phase X- and -ray light curves of gamma-ray bursts (GRBs) exhibit erratic and complex behaviour, often with multiple pulses. The temporal shape of individual pulses i…
