Detection of Very-High Energy Gamma-Rays from the BL Lac Object PG 1553+113 with the MAGIC Telescope
The MAGIC telescope has observed very-high energy gamma-ray emission from the BL Lac object PG 1553+113 in 2005 and 2006 at an overall significance is 8.8σ . The light curve shows no significant flux variations on a daily timescale. The flux level during 2005 was, however, significantly higher as compared to 2006. The differential energy spectrum between ∼90 GeV and 500 GeV is well described by...
متن کاملDiscovery of Very High Energy gamma-ray emission from the distant BL Lac object H2356-309 with the H.E.S.S. Cherenkov Telescopes
The H.E.S.S.(High Energy Stereoscopic System) array of imaging Cherenkov telescopes has recently discovered the most distant extra-galactic Very High Energy (VHE, E>160GeV) gamma-ray emitters. Located at a redshift of z=0.165, the extreme synchrotron BL Lac object H2356-309 was observed with H.E.S.S. in a simultaneous multi-wavelength campaign including radio, optical and X-ray observatories. U...
متن کاملThe luminous host galaxies of high redshift BL Lac objects
We present the first near-infrared K s-band (2.1 µm) imaging study of a sizeable sample of 13 high redshift (0.6 < z < 1.3) BL Lac objects in order to characterize the properties of their host galaxies. We are able to clearly detect the surrounding nebulosity in eight objects, and marginally in three others. In all the well resolved objects, we find that the host galaxy is well represented by a...
متن کاملBL Lac Contribution to the Extragalactic Gamma-Ray Background
Very high energy gamma-rays (Eγ > 20 GeV) from blazars traversing cosmological distances through the metagalactic radiation field can convert to electron-positron pairs in photonphoton collisions. The converted gamma rays initiate electromagnetic cascades driven by inverseCompton scattering off the microwave background photons. The cascades shift the injected gamma ray spectrum to MeV-GeV energ...
