X-ray flares from dense shells formed in gamma-ray burst explosions
R. Hascoet, A. M. Beloborodov, F. Daigne +1
Bright X-ray flares are routinely detected by the Swift satellite during the early afterglow of gamma-ray bursts, when the explosion ejecta drives a blast wave into the external me…
The prompt-early afterglow connection in gamma-ray bursts: implications for the early afterglow physics
R. Hascoet, F. Daigne, R. Mochkovitch
The early X-ray afterglow of gamma-ray bursts revealed by Swift carried many surprises. We focus in this paper on the plateau phase whose origin remains highly debated. We confront…
The prompt-early afterglow connection in GRBs
R. Mochkovitch, F. Daigne, R. Hascoet
We study the observed correlations between the duration and luminosity of the early afterglow plateau and the isotropic gamma-ray energy release during the prompt phase. We discuss…
Prompt thermal emission in gamma-ray bursts
R. Hascoët, F. Daigne, R. Mochkovitch
GRB spectra appear non-thermal, but recent observations of a few bursts with Fermi GBM have confirmed previous indications from BATSE of the presence of an underlying thermal compo…
Evidence for a Photospheric Component in the Prompt Emission of the Short GRB120323A and its Effects on the GRB Hardness-Luminosity Relation
S. Guiriec, F. Daigne, R. Hascoët +12
The short GRB 120323A had the highest flux ever detected with the Fermi/GBM. Here we study its remarkable spectral properties and their evolution using two spectral models: (i) a s…
The origin of the late rebrightening in GRB 080503
R. Hascoët, F. Daigne, R. Mochkovitch
GRB 080503, detected by Swift, belongs to the class of bursts whose prompt phase consists of an initial short spike followed by a longer soft tail. It did not show any transition t…
