Abstract

We report the AGILE γ-ray observations and the results of the multiwavelength campaigns on seven flaring blazars detected by the mission: During two multiwavelength campaigns, we observed γ-ray activity from two Flat Spectrum Radio Quasars of the Virgo region, e.g. 3C 279 and 3C 273 (the latter being the first extragalactic source simultaneously observed with the γ-ray telescope and the hard X ray imager of the mission). Due to the large FOV of the AGILE/GRID instrument, we achieved an almost continuous coverage of the FSRQ 3C 454.3. The source showed flux above 10-6photons/cm2/s (E>100MeV) and showed day by day variability during all the AGILE observing periods. In the EGRET era, the source was found in high γ-ray activity only once. An other blazar, PKS 1510-089 was frequently found in high γ-ray activity. S5 071671, an intermediate BL Lac object, exhibited a very high γ-ray activity and fast γ-ray variability during a period of intense optical activity. We observed high γ-ray activity from W Comae, a BL Lac object, and Mrk 421, a high energy peaked BL Lac object. For this source, a multiwavelength campaign from optical to TeV has been performed. © 2010 Elsevier B.V. All rights reserved.
