ASTRI-Horn: first Cherenkov telescope in dual-mirror configuration to detect the Crab Nebula at TeV energies

Exactly 40 years after the first historical observation of Crab nebula at TeV energies, which opened the era of TeV astronomy with the Imaging Atmospheric Cherenkov Technique (IACT), another advancement in IACT technology has been achieved. The ASTRI-Horn Cherenkov Telescope, based on the innovative Schwarzschild-Couder dual-mirror configuration and equipped with an innovative camera, has detected the Crab Nebula at TeV energies for the first time, proving the viability of this technology.

The ASTRI telescope is part of the ASTRI-CTA Mini-Array - THE CTA PRECURSOR -  a project with the participation of INAF (Italy), and IAG-USP (Sao Paulo, Brazil) through the FAPESP Thematic Project (13/10559/5) (
