Multifrequency Observations of the Blazar 3C 279 in January 2006
WEBT Collaboration, W. Collmar, M. Böttcher +13
We report first results of a multifrequency campaign from radio to hard X-ray energies of the prominent gamma-ray blazar 3C 279, which was organised around an INTEGRAL ToO observat…
GRB 070311: a direct link between the prompt emission and the afterglow
C. Guidorzi, S. D. Vergani, S. Sazonov +30
We present prompt gamma-ray, early NIR/optical, late optical and X-ray observations of the peculiar GRB 070311 discovered by INTEGRAL, in order to gain clues on the mechanisms resp…
Swift observations of GRB 060614: an anomalous burst with a well behaved afterglow
V. Mangano, S. T. Holland, D. Malesani +22
GRB 060614 is a remarkable GRB observed by Swift with puzzling properties, which challenge current progenitor models. The lack of any bright SN down to very strict limits and the v…
Gamma Ray Bursts Flares detected and observed by the Swift Satellite
Guido Chincarini, Alberto Moretti, Patrizia Romano +11
The detection of flares with the Swift satellite triggered a lot of bservational and theoretical interest in these phenomena. As a consequence a large analysis effort started withi…
Rapid N_H changes in NGC 4151
S. Puccetti, F. Fiore, G. Risaliti +4
We have analyzed the two longest (elapsed time > 3 days) BeppoSAX observations of the X-ray brightest Seyfert galaxy, NGC 4151, to search for spectral variability on time-scales fr…
Prompt and afterglow early X-ray phases in the comoving frame. Evidence for Universal properties?
G. Chincarini, A. Moretti, P. Romano +38
We analyze the Swift XRT light curves and spectra of the gamma-ray bursts (GRBs) for which the redshift has been measured. The sample consists of seven GRBs. The soft X-ray light c…
