A systematic analysis of X-ray afterglows of GRB observed by XMM-Newton
Abstract
This work is part of a systematic re-analysis program of all the data of GRB X-ray afterglows observed so far, in order to constrain the GRB models. We present here a systematic analysis of those afterglows observed by XMM-Newton between January 2000 and January 2004. This dataset includes GRB 011211 and GRB 030329. We have obtained spectra, light curves and colors for these afterglows. In this paper we focus on the continuum spectral and temporal behaviour. We compare these values with the theoretical ones expected from the fireball model.We also tried to correlate them with other burst parameters, e.g. Epeak or the burst duration. We derive constraints about some burst parameters.
