The 2010 very high energy gamma-ray flare & 10 years of multi-wavelength observations of M 87
The H. E. S. S. Collaboration, :, A. Abramowski +442
Abridged: The giant radio galaxy M 87 with its proximity, famous jet, and very massive black hole provides a unique opportunity to investigate the origin of very high energy (VHE;…
MAGIC observations of the giant radio galaxy M87 in a low emission state between 2005 and 2007
Karsten Berger, Dijana Dominis Prester, Fabrizio Tavecchio +1
We present the results of a long M87 monitoring campaign in very high energy -rays with the MAGIC-I Cherenkov telescope. A total of 150 hours of data was gathered between 2005 a…
Simultaneous Planck, Swift, and Fermi observations of X-ray and gamma-ray selected blazars
P. Giommi, G. Polenta, A. Lahteenmaki +92
We present simultaneous Planck, Swift, Fermi, and ground-based data for 105 blazars belonging to three samples with flux limits in the soft X-ray, hard X-ray, and gamma-ray bands.…
The long-lasting activity of 3C 454.3. GASP-WEBT and satellite observations in 2008-2010
C. M. Raiteri, M. Villata, M. F. Aller +6
We present multiwavelength observations of 3C 454.3 from April 2008 to March 2010. The radio to optical data are mostly from the GASP-WEBT, UV and X-ray data from Swift, and gamma-…
MAGIC observations and multiwavelength properties of the quasar 3C279 in 2007 and 2009
The MAGIC Collaboration, J. Aleksić, L. A. Antonelli +144
Context. 3C 279, the first quasar discovered to emit VHE gamma-rays by the MAGIC telescope in 2006, was reobserved by MAGIC in January 2007 during a major optical flare and from De…
PG 1553+113: five years of observations with MAGIC
MAGIC Collaboration, J. Aleksić, E. A. Alvarez +156
We present the results of five years (2005-2009) of MAGIC observations of the BL Lac object PG 1553+113 at very high energies (VHEs, E > 100 GeV). Power law fits of the individual…
