چکیده

The flat-spectrum radio-quasar 3C279 (z=0.536) is the most distant object detected at very high energy (VHE) γ-rays. It is thus an important beacon for the study of the interaction of the VHE γ-rays with the Extra-galactic Background Light (EBL). Previous observations by EGRET showed a highly variable flux that can differ up to a factor of 100. In this paper results from an observation campaign during an optical flare in January 2007 will be presented and previous results from the 2006 observation campaign will be summarized.

Intrinsic absorption in 3C 279 at GeV-TeV energies and consequences for estimates of the EBL

We revisit the limits of the level of the extragalactic background light (EBL) recently reported by the MAGIC collaboration based on the observed γ-ray spectrum of the quasar 3C279, considering the impact of absorption of high-energy γ-ray photons inside the broad line region (BLR) of the quasar. We use the photoionization code CLOUDY to calculate the expected optical-UV radiation field inside ...

MAGIC observations and multifrequency properties of the flat spectrum radio quasar 3C 279 in 2011

Aims. We study the multifrequency emission and spectral properties of the quasar 3C 279 aimed at identifying the radiation processes taking place in the source. Methods. We observed 3C 279 in very-high-energy (VHE, E > 100 GeV) γ-rays, with the MAGIC telescopes during 2011, for the first time in stereoscopic mode. We combined these measurements with observations at other energy bands: in high-e...

The unprecedented optical outburst of the quasar 3 C 454 . 3 The WEBT campaign of 2004 – 2005 ⋆

Context. The radio quasar 3C 454.3 underwent an exceptional optical outburst lasting more than 1 year and culminating in spring 2005. The maximum brightness detected was R = 12.0, which represents the most luminous quasar state thus far observed (MB ∼ −31.4). Aims. In order to follow the emission behaviour of the source in detail, a large multiwavelength campaign was organized by the Whole Eart...

MAGIC multiwavelength observations: policy, and some recent results

MAGIC, 17 meters of diameter, is the world’s largest single dish Imaging Atmospheric Cherenkov Telescope, and reaches in the analysis the lowest energy threshold (60 GeV) among the VHE gamma detectors. Completed in September 2004, MAGIC started full operation with its first cycle of data taking in February 2005. MAGIC observations in the galaxy cover, among others, supernova remnants, the Galac...

Implications of the VHE gamma-ray detection of the Quasar 3C279

The Major Atmospheric Gamma-Ray Imaging Cherenkov Telescope very high energy (VHE) γ -ray astronomy collaboration recently reported the detection of the quasar 3C279 at > 100 GeV γ -ray energies. Here, we present simultaneous optical (BVRI) and X-ray (RXTE PCA) data from the day of the VHE detection and discuss the implications of the snapshot spectral energy distribution for jet models of blaz...
