INTEGRAL observations of the blazar Mrk 421 in outburst (Results of a multi-wavelength campaign)

G. G. Lichti, E. Bottacini, M. Ajello +15

We report the results of a multi-wavelength campaign on the blazar Mrk 421 during outburst. We observed four strong flares at X-ray energies that were not seen at other wavelengths…

Multifrequency Observations of the Blazar 3C 279 in January 2006

WEBT Collaboration, W. Collmar, M. Böttcher +13

We report first results of a multifrequency campaign from radio to hard X-ray energies of the prominent gamma-ray blazar 3C 279, which was organised around an INTEGRAL ToO observat…

INTEGRAL and Multiwavelength Observations of the Blazar Mrk 421 during an Active Phase

G. G. Lichti, E. Bottacini, P. Charlot +9

A ToO observation of the TeV-emitting blazar Mrk 421 with INTEGRAL was triggered in June 2006 by an increase of the RXTE count rate to more than 30 mCrab. The source was then obser…

Day-Scale Variability of 3C 279 and Searches for Correlations in Gamma-Ray, X-Ray, and Optical Bands

R. C. Hartman, M. Villata, T. J. Balonek +36

Light curves of 3C 279 are presented in optical (R-band), X-rays (RXTE/PCA), and gamma rays (CGRO/EGRET) for 1999 Jan-Feb and 2000 Jan-Mar. During both of those epochs the gamma-ra…

COMPTEL Observations of AGN at MeV-Energies

W. Collmar, K. Bennett, H. Bloemen +9

The COMPTEL experiment aboard CGRO, exploring the previously unknown sky at MeV-energies, has so far detected 10 Active Galactic Nuclei (AGN): 9 blazars and the radio galaxy Centau…

Multiwavelength Observations of a Dramatic High Energy Flare in the Blazar 3C 279

A. E. Wehrle, E. Pian, C. M. Urry +3

The blazar 3C 279, one of the brightest identified extragalactic objects in the gamma-ray sky, underwent a flare of a factor 10 amplitude in gamma-rays towards the end of a 3-week…
