The WEBT Campaign on the Blazar 3C279 in 2006
M. Boettcher
The quasar 3C279 was the target of an extensive multiwavelength monitoring campaign from January through April 2006, including an optical-IR-radio monitoring campaign by the Whole…
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…
X-ray/UV/Optical follow-up of the blazar PKS 2155-304 after the giant TeV flares of July 2006
L. Foschini, G. Ghisellini, F. Tavecchio +12
We present all the publicly available data, from optical/UV wavelengths (UVOT) to X-rays (XRT, BAT), obtained from Swift observations of the blazar PKS 2155-304, performed in respo…
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…
Spectroscopic monitoring of the BL Lac object AO 0235+164
C. M. Raiteri, M. Villata, A. Capetti +3
We performed optical spectroscopic monitoring of the BL Lac object AO 0235+164 (z=0.94) with the VLT and TNG telescopes from Aug. 2003 to Dec. 2004, during an extended WEBT campaig…
