Science with IUE and the Growth of an Astrophysical Group in Milan: from X-Ray Binaries to AGN
Renato Falomo, Laura Maraschi, Elena Pian +1
The contribution of an astrophysics group based in Milan to the science with the IUE satellite during its almost 20 years lifetime has focussed on high energy sources, of both gala…
Fast X-ray Variability of PKS 2155-304: A Cross Correlation Analysis
A. Treves, Y. H. Zhang, A. Celotti +7
PKS 2155-304 is one of the prototypes of BL Lac objects. Its spectral energy distribution is known from the radio to the TeV band and has two peaks, one in the soft X-rays and the…
Extreme Synchrotron Blazars in Outburst: the Potentiality of INTEGRAL Imaging and Spectroscopy
Elena Pian, Giuseppe Malaguti, Laura Maraschi +2
Only ~10 blazars have been detected in soft gamma-rays by OSSE and the PDS, often in flaring state. We investigate the impact of the imaging and spectral capabilities of the IBIS i…
BeppoSAX Observations of the BL Lac Object Mkn 501 in an Intermediate State
Elena Pian, Eliana Palazzi, Lucio Chiappetti +8
The BL Lac object Mkn 501 was observed with the BeppoSAX satellite at three epochs in April-May 1998, simultaneously with the Whipple and HEGRA Cherenkov telescopes. The X-ray spec…
The absorption properties of gamma-ray burst afterglows measured by BeppoSAX
Alan Owens, M. Guainazzi, T. Oosterbroek +14
We present an analysis of the X-ray absorption properties of 6 gamma-ray burst (GRB) afterglows measured with BeppoSAX. Between 8 hrs and 20 hrs after the initial GRB trigger, indi…
BeppoSAX Observations of PKS 2155-304 during an active Gamma-ray State
L. Maraschi, L. Chiappetti, F. Tavecchio +8
PKS 2155-304 was observed with BeppoSAX in November 1997 for 64 ksec (total elapsed time 33.5 hours) and, for the first time, simultaneously in gamma-rays with EGRET on board the C…
