Swift follow-up of the gigantic TeV outburst of PKS 2155-304 in 2006
L. Foschini, G. Ghisellini, F. Tavecchio +12
At the end of July 2006, the blazar PKS 2155-304 (z=0.116) underwent a strong outburst observed at TeV energies by HESS (up to 17 Crab flux level at E > 200 GeV). The Swift satelli…
Ten-year optical monitoring of PKS 0735+178: historical comparison, multiband behaviour and variability timescales
S. Ciprini, L. O. Takalo, G. Tosti +7
New data and results on the optical behaviour of the blazar PKS 0735+178 are presented. In addition the whole historical light curve, and a new photometric calibration of compariso…
BL Lacertae: the multiwavelength campaign of 2000
M. Ravasio, G. Tagliaferri, G. Ghisellini +9
We present two BeppoSAX observations of BL Lacertae as part of a multiwavelength radio-to-TeV campaign. During the first observation we observe a faint Compton spectrum, while duri…
Broadband Spectra and Variability of BL Lacertae in 2000
M. Boettcher, H. D. Aller, M. F. Aller +6
We have organized an extensive multiwavelength campaign on BL Lacertae in the second half of 2000. Simultaneous or quasi-simultaneous observations were taken at radio frequencies,…
Two BeppoSAX observations of BL Lac
G. Tagliaferri, G. Ghisellini, M. Ravasio +14
We present the results of two ToO BeppoSAX observations of BL Lac. During the first observation we detected both the synchrotron and the Compton components. Fast time variability w…
The concave X-ray spectrum of the blazar ON 231: the signature of intermediate BL Lac objects
G. Tagliaferri, G. Ghisellini, P. Giommi +17
ON 231 was observed with BeppoSAX in May and June 1998, following an exceptional optical outburst which occured in April--May. We measured the X-ray spectrum from 0.1 up to 100 keV…
