SARG: the high resolution spectrograph
Gratton R., Bonanno G., Bruno P. +8
SARG is the high resolution spectrograph of TNG. It has been in operation since late spring 2000. SARG is a cross dispersed echelle spectrograph; it offers both single object and l…
First detection of the Crab Nebula at TeV energies with a Cherenkov telescope in a dual-mirror Schwarzschild-Couder configuration: the ASTRI-Horn telescope
S. Lombardi, O. Catalano, S. Scuderi +89
We report on the first detection of very high-energy (VHE) gamma-ray emission from the Crab Nebula by a Cherenkov telescope in dual-mirror Schwarzschild-Couder (SC) configuration.…
A 3.9 km baseline intensity interferometry photon counting experiment
Giampiero Naletto, Luca Zampieri, Cesare Barbieri +6
In the last years we have operated two very similar ultrafast photon counting photometers (Iqueye and Aqueye+) on different telescopes. The absolute time accuracy in time tagging t…
SHARK-NIR, the coronagraphic camera for LBT, moving toward construction
Jacopo Farinato, Francesca Bacciotti, Carlo Baffa +37
SHARK-NIR is one of the two coronagraphic instruments proposed for the Large Binocular Telescope. Together with SHARK-VIS (performing coronagraphic imaging in the visible domain),…
Intensity Interferometry with Aqueye+ and Iqueye in Asiago
L. Zampieri, G. Naletto, C. Barbieri +6
Since a number of years our group is engaged in the design, construction and operation of instruments with very high time resolution in the optical band for applications to Quantum…
Aqueye+: a new ultrafast single photon counter for optical high time resolution astrophysics
L. Zampieri, G. Naletto, C. Barbieri +7
Aqueye+ is a new ultrafast optical single photon counter, based on single photon avalanche photodiodes (SPAD) and a 4-fold split-pupil concept. It is a completely revisited version…
A facility to evaluate the focusing performance of mirrors for Cherenkov Telescopes
Rodolfo Canestrari, Enrico Giro, Giacomo Bonnoli +6
Cherenkov Telescopes are equipped with optical dishes of large diameter -- in general based on segmented mirrors -- with typical angular resolution of a few arc-minutes. To evaluat…
