Results of WEBT, VLBA and RXTE monitoring of 3C 279 during 2006-2007
V. M. Larionov, S. G. Jorstad, A. P. Marscher +2
We present radio-to-optical data taken by the WEBT, supplemented by VLBA and RXTE observations, of 3C 279. Our goal is to use this extensive database to draw inferences regarding t…
A new activity phase of the blazar 3C 454.3. Multifrequency observations by the WEBT and XMM-Newton in 2007-2008
C. M. Raiteri, M. Villata, V. M. Larionov +2
We present and analyse the WEBT multifrequency observations of 3C 454.3 in the 2007-2008 observing season, including XMM-Newton observations and near-IR spectroscopic monitoring, a…
AGILE detection of intense gamma-ray emission from the blazar PKS 1510-089
G. Pucella, V. Vittorini, F. D'Ammando +59
We report the detection by the AGILE (Astro-rivelatore Gamma a Immagini LEggero) satellite of an intense gamma-ray flare from the source AGL J1511-0909, associated with the powerfu…
AGILE detection of variable gamma-ray activity from the blazar S5 0716+714 in September-October 2007
A. W. Chen, F. D'Ammando, M. Villata +65
We report the gamma-ray activity from the intermediate BL Lac S5 0716+714 during observations acquired by the AGILE satellite in September and October 2007. These detections of act…
Multifrequency monitoring of the blazar 0716+714 during the GASP-WEBT-AGILE campaign of 2007
M. Villata, C. M. Raiteri, V. M. Larionov +5
Since the CGRO operation in 1991-2000, one of the primary unresolved questions about the blazar gamma-ray emission has been its possible correlation with the low-energy (in particu…
Multifrequency variability of the blazar AO 0235+164. The WEBT campaign in 2004-2005 and long-term SED analysis
C. M. Raiteri, M. Villata, M. Kadler +3
A huge multiwavelength campaign targeting the blazar AO 0235+164 was organized by the Whole Earth Blazar Telescope (WEBT) in 2003-2005 to study the variability properties of the so…
