The Cherenkov Telescope Array: an advanced facility for the Ground-based High Energy Gamma Ray Astronomy.

Abstract

In the past 15 years, Very High Energy (VHE) γ-ray ex-periments as H.E.S.S., MAGIC and VERITAS have been very successfulunveiling the mysteries of the non thermal Universe using Cherenkovtelescopes based on Earth. The next logical step in the evolution of theγ-ray Astronomy was to gather their efforts to built a global and innovat-ing ground based facility: the Cherenkov Telescope Array (CTA). Thishas been conceived as an array of Cherenkov telescopes working as anopen observatory, covering a wide energy range, with an enhanced sensi-tivity and improved spatial, temporal and energy resolution. The projectis at the end of its Preparatory Phase. The decision on its location isabout to be taken and the construction is expected to begin in 2015.We briefly describe the general status of the project and the argentineanparticipation.
