The CTA Observatory

R. M. Wagner, E. J. Lindfors, A. Sillanpää +1

In recent years, ground-based very-high-energy (VHE; E>100 GeV) gamma-ray astronomy has experienced a major breakthrough with the impressive astrophysical results obtained mainly b…

Variability and stability in blazar jets on time scales of years: Optical polarization monitoring of OJ287 in 2005-2009

C. Villforth, K. Nilsson, J. Heidt +45

(Abridged) OJ287 is a BL Lac object that has shown double-peaked bursts at regular intervals of ~12 yr during the last ~40 yr. We analyse optical photopolarimetric monitoring data…

WEBT multiwavelength monitoring and XMM-Newton observations of BL Lacertae in 2007-2008. Unveiling different emission components

C. M. Raiteri, M. Villata, A. Capetti +8

In 2007-2008 we carried out a new multiwavelength campaign of the Whole Earth Blazar Telescope (WEBT) on BL Lacertae, involving three pointings by the XMM-Newton satellite, to stud…

The GASP-WEBT monitoring of 3C 454.3 during the 2008 optical-to-radio and gamma-ray outburst

M. Villata, C. M. Raiteri, M. A. Gurwell +6

Since 2001, the radio quasar 3C 454.3 has undergone a period of high optical activity, culminating in the brightest optical state ever observed, during the 2004-2005 outburst. The…

The June 2008 flare of Markarian 421 from optical to TeV energies

R. M. Wagner, I. Donnarumma, J. Grube +6

We present optical to very-high energy (VHE) gamma-ray observations of Mrk 421 between 2008 May 24 and June 23. A high-energy (HE) gamma-ray signal was detected by AGILE-GRID durin…

Suzaku and Multi-wavelength Observations of OJ 287 during the Periodic Optical Outburst in 2007

Hiromi Seta, Naoki Isobe, Makoto S. Tashiro +10

Suzaku observations of the blazar OJ 287 were performed in 2007 April 10--13 and November 7--9. They correspond to a quiescent and a flaring state, respectively. The X-ray spectra…
