Thanks its expected overall performance, better than those current telescopes' arrays for...
We report on the first detection of very high-energy (VHE) gamma-ray emission from Crab Nebula by a Cherenkov telescope in dual-mirror Schwarzschild-Couder (SC) configuration. The result has been achieved means 4 m size ASTRI-Horn telescope, operated Mt. Etna (Italy) and developed context Telescope Array Observatory preparatory phase. SC design is aplanatic characterized small plate scale, allowing us to implement large field view cameras with small-size pixel sensors high compactness....
In this paper, the development of dual mirror Small Size Telescopes (SST) for Cherenkov Telescope Array (CTA) is reviewed. Up to 70 SST, with a primary diameter 4 m, will be produced and installed at CTA southern site. These allow investigation gamma-ray sky highest energies accessible CTA, in range from about 1 TeV 300 TeV. The telescope presented contribution characterized by two major innovations: use Schwarzschild-Couder configuration an innovative camera using as sensors either...
In the context of Cherenkov Telescope Array observatory project, ASTRI SST-2M end-to-end prototype telescope, entirely supported by Italian National Institute Astrophysics, is designed to detect cosmic primary gamma ray energies from few TeV up hundreds TeV.

The analysis of Perseus data collected with the Medium Energy Concentrator Spectrometer (MECS) on board Beppo-SAX shows that ratio flux 8 keV line complex (dominated by Fe K$_β$ emission) over 6.8 K$_α$ is significantly larger than predicted standard thermal emission codes. Moreover spatially resolved spectra above decreases increasing cluster radius. We find that, amongst various explanations we consider, most likely requires plasma to be optically thick for resonant scattering at energy...
We present the results of a BeppoSAX observation Supernova Remnant MSH 15-52, associated with pulsar PSR B1509-58, and discuss its main morphological spectroscopic properties in 1.6-200 keV energy range (MECS PDS instruments).
