Supernova remnants

The Supernova Remnants (SNRs) are the remains of a Supernova explosion. SNRs are among the most luminous TeV sources and typically have hard spectra, which makes them promising ASTRI sources. The next generation of of Cherenkov telescope will extend the known energy range up to the 100 TeV (ASTRI) and 200TeV (CTA), revealing the true nature of the emission process for this kind of objects.
