The Amerigo Vespucci as a traveling laboratory for studying the cosmic-ray fluxes at sea level
Davide Cerasole, Federica Cuna, Gaia De Palma +13
We have installed and operated a plastic scintillator detector counter to measure the flux of cosmic radiation during the 2023-2025 tour of the historical vessel Amerigo Vespucci.…
Design and Performance of the Upgraded Prototype Schwarzschild-Couder Telescope Camera Module
Giovanni Ambrosi, Carla Aramo, Mattia Barbanera +54
The Cherenkov Telescope Array Observatory (CTAO) is a ground-based observatory that will improve upon the sensitivities of the current generation of very-high-energy gamma-ray inst…
The simulation chain for the Terzina Cherenkov telescope on board the NUSES space mission
M. Abdullahi, R. Aloisio, F. Arneodo +74
The Terzina telescope is designed to detect ultra-high energy cosmic rays (UHECRs) and Earth-skimming neutrinos from a 550 km low-Earth orbit (LEO) by observing Cherenkov light emi…
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…
Interpolation of Instrument Response Functions for the Cherenkov Telescope Array in the Context of pyirf
Rune Michael Dominik, Maximilian Linhoff, Julian Sitarek
The Cherenkov Telescope Array (CTA) will be the next generation ground-based very-high-energy gamma-ray observatory, constituted by tens of Imaging Atmospheric Cherenkov Telescopes…
Performance update of an event-type based analysis for the Cherenkov Telescope Array
Juan Bernete, Orel Gueta, Tarek Hassan +3
The Cherenkov Telescope Array (CTA) will be the next-generation observatory in the field of very-high-energy (20 GeV to 300 TeV) gamma-ray astroparticle physics. The traditional ap…
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)…
Design and Performance of the Prototype Schwarzschild-Couder Telescope Camera
Colin B. Adams, Giovanni Ambrosi, Michelangelo Ambrosio +86
The prototype Schwarzschild-Couder Telescope (pSCT) is a candidate for a medium-sized telescope in the Cherenkov Telescope Array. The pSCT is based on a novel dual mirror optics de…
Design and performance of the prototype Schwarzschild-Couder Telescope camera
C. B. Adams, G. Ambrosi, M. Ambrosio +71
The Cherenkov Telescope Array (CTA) is the next-generation ground-based observatory for very-high-energy gamma-ray astronomy. An innovative 9.7 m aperture, dual-mirror Schwarzschil…
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…
