ASTRI (Astrophysics with Italian Replicating Technology Mirrors) – a Small Size Telescope (prototype & array)

INAF for gamma astronomy with aplanatic two-mirror telescopes between 1 and 100 TeV

ASTRI in brief


The ASTRI Team is made up of staff from various INAF Institutes and Italian Universities. The University of São Paulo in Brazil/FAPESP and the North West University of South Africa are also formally part of it. The ASTRI Project Office is at INAF – OAB Brera and the prototype telescope is installed at the INAF – OACT observatory in Serra La Nave.


ASTRI was born as a MIUR flagship project aimed at developing the next generation of IACT telescopes (Atmospheric Cherenkov Telescope Imaging) for astronomy in gamma rays from the ground. ASTRI is the first telescope for Cherenkov astronomy that has adopted the optical configuration of the Schwarzschild-Couder type.


Gamma-ray astronomy allows the in-depth study of the violent Universe, from supernova explosions to Active Galactic Nuclei through dark matter.
