The extragalactic optical - infrared background radiation , its time evolution and the cosmic photon - photon opacity

The background radiations in the optical and the infrared constitute a relevant cause of energy loss in the propagation of high energy particles through space. In particular, TeV observations with Cherenkov telescopes of extragalactic sources are influenced by the opacity effects due to the interaction of the very high-energy source photons with the background light. With the aim of assessing w...

Detecting a Unique EBL Signature with TeV Gamma Rays

We discuss prospects for detecting a spectral break in γ-ray spectra of blazars due to the extragalactic background light (EBL) density falling off between the near and mid-IR. A measurable spectral change in the TeV spectra at 1 TeV could arise from a rapid or slow drop in the EBL density above ≈ 1 um. This effect is mediated by the ratio of the near to mid-IR density of EBL. A detection of su...

AGILE and blazar studies

During the first two years of observation, AGILE detected several blazars at high significance: 3C 279, 3C 454.3, PKS 1510–089, S5 0716+714, 3C 273, W Comae, Mrk 421 and PKS 0537–441. We obtained long-term coverage of 3C 454.3, for a total of more than three months at energies above 100 MeV. 3C 273 was the first blazar detected simultaneously by the AGILE gamma-ray detector and by its hard X-ra...

Multi-wavelength Observations of the TeV Blazars Mkn 421, 1ES1959+650, and H1426+428 with the HEGRA Cherenkov Telescopes and the RXTE X-ray Satellite

Recent results obtained with the HEGRA system of imaging Cherenkov telescopes on the TeV emission of the Blazars Mkn 421 (z = 0.030), 1ES1959+650 (z = 0.047), and H1426+428 (z = 0.129) are reported. For Mkn 421, a close connection of the average flux level and spectral shape has been observed during the periods of increased activity in the years 2000 and 2001. Simultaneously taken data with the...
