Time lags as proxy of spectral evolution in gamma-ray bursts
C. Maraventano, F. Daigne, R. Mochkovitch +3
Positive lags in gamma-ray bursts (GRBs), where hard photons anticipate softer ones, provide a unique window into the temporal evolution of their prompt emission. Negative lags, wh…

XRF 241001A/SN 2024aiiq: A faint soft X-ray transient detected by SVOM with a broad-line type Ic supernova revealed by JWST
B. Schneider, M. Brunet, B. P. Gompertz +61
X-ray flashes (XRFs) are a type of gamma-ray burst (GRB) with prompt emission predominantly below 30 keV and have been poorly detected by previous missions. The advent of the SVOM…

GRB 221009A and the Apparently Most Energetic Gamma-Ray Bursts
J-L. Atteia, L. Bouchet, J-P. Dezalay +7
Gamma-Ray Bursts (GRBs) are often referred to as the most luminous explosions in the Universe, due to their short and highly luminous prompt emission. This apparent luminosity, how…
