Studio delle performance del sistema combinato di telescopi MAGIC e LST-1 con osservazioni congiunte della Crab Nebula

This thesis deals with the evaluation of the performance of a system of Imaging Atmospheric Cherenkov Telescopes (IACTs), instruments used for ground-based gamma-ray astronomy which detect the Cherenkov light emitted by Extensive Air Showers (EAS), particle cascades produced by cosmic rays interacting with the Earth atmosphere. This system includes the two 17-m diameter telescopes constituting the MAGIC experiment and the prototype of the 23-m Large-Sized Telescopes (LST-1) that will compose the Cherenkov Telescope Array (CTA) Northern array. The telescopes are located at ORM (Observatorio del Roque de los Muchachos, La Palma, Canary Islands). Both simulations and real observations of the Crab Pulsar Wind Nebula, the standard candle in gamma-ray astronomy, have been used to evaluate the system performance, in terms of energy and angular resolutions and point source sensitivity. Finally the measured spectrum of the Crab Nebula provides the confirmation of the estimated performance. During the thesis part of the pipeline (magic-cta-pipe) used to process and to analyze the data has been developed and optimized.
