Imaging Atmospheric Cherenkov Telescopes pointing determination using the trajectories of the stars in the field of view
Mykhailo Dalchenko, Matthieu Heller
We present a new approach to the pointing determination of Imaging Atmospheric Cherenkov Telescopes (IACTs). This method is universal and can be applied to any IACT with minor modi…
Performance of the joint LST-1 and MAGIC observations evaluated with Crab Nebula data
H. Abe, K. Abe, S. Abe +365
Aims. LST-1, the prototype of the Large-Sized Telescope for the upcoming Cherenkov Telescope Array Observatory, is concluding its commissioning in Observatorio del Roque de los Muc…
Characterization of SiPM and development of test bench modules for the next-generation cameras for Large-Sized Telescopes for Cherenkov Telescope Array
Takayuki. Saito, K. Hashiyama, H. Iwasaki +5
The recent improvements in the performance of the silicon photomultipliers (SiPMs) made them attractive options as photo sensors of imaging atmospheric Cherenkov telescopes (IACTs)…
Cross-calibration and combined analysis of the CTA-LST prototype and the MAGIC telescopes
Y. Ohtani, A. Berti, D. Depaoli +13
The Cherenkov Telescope Array (CTA) will be the next generation gamma-ray observatory, which will consist of three kinds of telescopes of different sizes. Among those, the Large Si…
Reconstruction of extensive air shower images of the first Large Size Telescope prototype of CTA using a novel likelihood technique
Gabriel Emery, Cyril Alispach, Mykhailo Dalchenko +3
Ground-based gamma-ray astronomy aims at reconstructing the energy and direction of gamma rays from the extensive air showers they initiate in the atmosphere. Imaging Atmospheric C…
Commissioning of the camera of the first Large Size Telescope of the Cherenkov Telescope Array
T. Saito, C. Delgado, O. Blanch +30
The first Large Size Telescope (LST-1) of the Cherenkov Telescope Array has been operational since October 2018 at La Palma, Spain. We report on the results obtained during the cam…
Monitoring the pointing of the prototype LST-1 using star reconstruction in the Cherenkov camera
L. Foffano, A. Carosi, M. Dalchenko +3
The first Large-Sized Telescope (LST-1) proposed for the forthcoming Cherenkov Telescope Array (CTA) has started to operate in 2019 in La Palma. The large structure of LST-1 - with…
The Crab Nebula Spectrum at ~100 TeV Measured with MAGIC under Very Large Zenith Angles
Michele Peresano, Razmik Mirzoyan, Ievgen Vovk +5
The Crab Nebula was discovered as the first very-high-energy gamma-ray source by the Whipple Observatory in 1989. Thirty years after its discovery it is still the reference source…
Pointing System for the Large Size Telescopes Prototype of the Cherenkov Telescope Array
Darko Zarić, Stefan Cikota, Armand Fiasson +5
The pointing system of the prototype of the Large Size Telescope (LST-1) for the Cherenkov Telescope Array observatory, should ensure mapping of the gamma-ray image of a point-like…
Extending the observation limits of Imaging Air Cherenkov Telescopes toward horizon
Razmik Mirzoyan, Ievgen Vovk, Michele Peresano +6
Usually the Imaging Atmospheric Cherenkov Telescopes, used for the ground-based gamma-ray astronomy in the very high energy range 50 GeV - 50 TeV, perform air shower observations t…
Limits on the flux of tau neutrinos from 1 PeV to 3 EeV with the MAGIC telescopes
