Intrinsic spectra and energetics of BeppoSAX Gamma-Ray Bursts with known redshifts
L. Amati, F. Frontera, M. Tavani +13
We present the main results of a study of spectral and energetics properties of twelve gamma-ray bursts (GRBs) with redshift estimates. All GRBs in our sample were detected by Bepp…
A BeppoSax view of the Centaurus Cluster
S. Molendi, S. De Grandi, M. Guainazzi
We present results from the analysis of a BeppoSAX observation of the Centaurus Cluster. The radial metal abundance profile shows evidence of a large enhancement in the core, where…
The Infrared Counterpart of the X-ray Burster KS 1731--260
R. P. Mignani, S. Chaty, F. Mirabel +1
We present JK' infrared images of the X-ray transient KS 1731--260, obtained in 1997 and in 1998 with IRAC2b at the ESO/MPI 2.2-m telescope at La Silla. Using as a reference the re…
