Synoptics study of blazars detected at very high energy gamma-rays
- Conference date: 9–13 July 2012
- Location: Heidelberg, Germany
Due to the increased sensitivity of the present generation of Cherenkov telescopes, the knowledge of the Very High Energy (VHE, E>100 GeV) gamma-ray sky has substantially increased in the past years. In particular, in the extragalactic sky a wealth of new sources and source classes has been discovered. Today, more than 50 extragalactic sources have been detected, 45 of them being Blazars, i.e., Active Galactic Nuclei (AGNs) with their jet aligned close to the line of sight to the observer. A population study of them is being carried out investigating the correlation among different physical parameters inherent to the VHE measurements as well parameters coming from other wavelengths, extending beyond quantities strictly related to the emission characteristics of the blazar (e.g. BH mass). In this contribution, preliminary results from the population study are presented. This study is particularly interesting for the future perspective of present generation of Cherenkov telescopes as well as for the future Cherenkov Telescope Array (CTA) in order to identify the characteristics of the sources which are likely to be detected at such energy range.
