MAGIC is an experiment designed for the detection of very high-energy gamma rays, which are indicative of extremely violent processes in the universe, such as the mass falling into a black hole or stellar explosions. Very high-energy gamma rays (E > 50 GeV) can be detected from Earth, as they produce a cascade of particles when interacting with the atmosphere. This particle cascade generates a faint flash of Cherenkov light produced by particles traveling faster than light propagates through the atmosphere. The Cherenkov light is collected by enormous telescopes and focused onto a camera, producing an image of the cascade.
Data analysis for the MAGIC experiment involves the three-dimensional reconstruction of the cascade based on Cherenkov images. The primary goal is to determine the direction and energy of the gamma ray that triggered the cascade.
A constant and detailed simulation of both atmospheric cascades and the detector’s response under different data-taking conditions is crucial. Therefore, simulated data is continuously generated to validate the acquired experimental data.
The analyses conducted by our group on CloudVeneto have been the subject of numerous scientific articles published in prestigious international journals. Among these articles, a recent significant contribution pertains to the association of a gamma-ray source with a neutrino event, marking the inception of new ‘multi-messenger’ astrophysics involving neutrinos.
