VHE gamma ray astrophysics and a Polish contribution to the CTA project

Exploring the Universe in the Very High Energy (100 GeV - 100 TeV) gamma rays is a relatively new research field of astrophysics, of importance for fundamental physics and cosmology also. The most efficient tool to study VHE gamma rays are Imaging Arrays of Cherenkov Telescopes (IACT) situated on earth. In the talk I will present a short review of selected results obtained by existing arrays, in particular by the H.E.S.S. experiment operated with Polish contribution in Namibia. Then, I will shortly present a current status of the Cherenkov Telescope Array (CTA) project and a progress with main Polish instrumental contributions to it: the small Cherenkov telescope SST-1M, composite mirror development for the medium size telescope MST and the CTA Science Gateway software development.
