Abstract
In spite of the huge advances in the knowledge of the afterglow emission properties and their interpretation, from BeppoSAX to Swift, the GRB phenomenon is still far from being fully understood. Of crucial importance is the study of the prompt emission, which is more directly connected to the original explosive process. The goal of this proposal is to use all the available GRB archives, inclusive of the data archive of the BeppoSAX GRBM, which is being made public by ASI-ASDC, for deep studies of the prompt emission properties. Concerning the GRBM, whose GRB catalogue has already been published by us (Frontera et al. 2009, ApJS), data products of each GRB will be made accessible to the entire Community. Concerning the GRB studies, we aim to pursue further systematic studies with the GRBM data and, jointly, those from other GRB catalogues (e.g. for the common GRBs, for classes of GRBs displaying common profile properties), through the following data analyses: a) systematic study and characterisation, through complementary timing techniques, of the GRB temporal variability up to 1 kHz. The GRBM large detection area and its high temporal resolution (down to 0.5 ms) are an ideal benchmark for the study of the evolution of the short time scale variability along the burst profile; b) comparison of the temporal and spectral properties of the Swift-BAT GRBs (15-150 keV) with those found with the BeppoSAX GRBM (40-700 keV) and WFC (2-28 keV) or with other instruments (e.g., BATSE, Fermi/GBM). Such a comparison, for the Swift GRBs with known redshift and optical properties (about 100), can offer the key for a better understanding of the numerous GRBs observed with other instruments and the possibleidentification of GRB subclasses; c) comparative studies of GRB temporal and spectral properties, to test existing correlations, search for new ones and to test GRB emission models (e.g., Lyutikov & Blandford 2003; Narayan & Kumar 2008; Lazar, Nakar & Piran 2009).I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
