BeppoSAX observations of 3C 273
Francesco Haardt
We present preliminary results of BeppoSAX AO1 observations of 3C 273 performed in January 1997. We also present a close comparison with data obtained during the satellite SVP, in…
Multiwavelength Observations of a Dramatic High Energy Flare in the Blazar 3C 279
A. E. Wehrle, E. Pian, C. M. Urry +3
The blazar 3C 279, one of the brightest identified extragalactic objects in the gamma-ray sky, underwent a flare of a factor 10 amplitude in gamma-rays towards the end of a 3-week…
BeppoSAX Observations of Unprecedented Synchrotron Activity in the BL Lac Object Mkn 501
Elena Pian, Giuseppe Vacanti, Gianpiero Tagliaferri +9
The BL Lac object Mkn 501, one of the only three extragalactic sources (with Mkn 421 and 1ES 2344+514) so far detected at TeV energies, was observed with the BeppoSAX satellite on…
Rosat, Asca and Osse Observations of the Broad Line Radio Galaxy 3C120
Paola Grandi, R. M. Sambruna, L. Maraschi +3
We present simultaneous observations of the superluminal radio galaxy 3C120 performed with the ASCA and GRO (OSSE) satellites on February-March 1994, as well as an analysis of all…
Multiwavelength Monitoring of the BL Lacertae Object PKS 2155-304 in May 1994. III. Probing the Inner Jet through Multiwavelength Correlations
C. Megan Urry, A. Treves, L. Maraschi +16
In May 1994 the BL Lac object PKS 2155-304 was observed continuously for ~10 d with IUE and EUVE and for 2 d with ASCA, as well as with ROSAT and with ground- based radio, IR, and…
