Are GRB 980425 and GRB 031203 real outliers or twins of GRB 060218 ?
GRB 980425 and GRB 031203 are apparently two outliers with respect to the correlation between the isotropic equivalent energy Eiso emitted in the prompt radiation phase and the peak frequency Epeak of the spectrum in a νFν representation (the so–called Amati relation). We discuss if these two bursts are really different from the others or if their location in the Eiso–Epeak plane is the result ...

We study the probability that three GRBs (980425, 030329, 031203) are found within z = 0.17, given the luminosity functions consistent with the logN − logS relationship for classical cosmological bursts (i.e., those observed by BATSE). We show that, in order for the probability of these three low-z events to be non-negligible (thus making it more likely that they belong to the same class of the...
متن کاملDust - scattered X - ray halos around gamma - ray bursts : GRB 031203 revisited and the new case of GRB 050713 A ⋆
Scattering by interstellar dust grains can produce time variable X-ray halos around gamma-ray bursts (GRB). In particular, an X-ray expanding ring is expected when a short pulse of X-ray radiation is scattered by a narrow layer of dust in our Galaxy. We present a new method to detect and analyze dust scattering expanding rings around gamma-ray bursts, using as an example XMM-Newton data of GRB ...
متن کاملGRB 050410 and GRB 050412 : are they really dark gamma - ray bursts ?
Aims. We present a detailed analysis of the prompt and afterglow emission of GRB 050410 and GRB 050412 detected by Swift for which no optical counterpart was observed. Methods. We analysed data from the prompt emission detected by the Swift BAT and from the early phase of the afterglow obtained by the Swift narrow field instrument XRT. Results. The 15−150 keV energy distribution of the GRB 0504...
متن کاملPrompt Ultraviolet-to-soft X-ray Emission of Gamma-ray Bursts: Application to Grb 031203?
We discuss the prompt emission of GRBs, allowing for γγ pair production and synchrotron self-absorption. The observed hard spectra suggest heavy pair-loading in GRBs. The re-emission of the generated pairs results in the energy transmission from high-energy gamma-rays to long-wavelength radiation. Due to strong self-absorption, the synchrotron radiation by pairs is in optically thick regime. Th...
