GRB X-ray plateaus as evidence that the afterglow begins before the prompt gamma-ray emission
C. Guidorzi, R. Maccary, M. Maistrello +3
Most GRB X-ray afterglow light curves are characterised by a plateau, followed by a normal power-law decay interpreted as afterglow emission. Despite the numerous alternative inter…

EP240801a/XRF 240801B: An X-ray Flash Detected by the Einstein Probe and Implications of its Multiband Afterglow
Shuai-Qing Jiang, Dong Xu, Agnes P. C. van Hoof +89
We present multiband observations and analysis of EP240801a, a low-energy, extremely soft gamma-ray burst (GRB) discovered on August 1, 2024 by the Einstein Probe (EP) satellite, w…
