Description
Several fundamental astrophysical phenomena in the Universe, like Cosmic ray acceleration, Black Holes accretion and compact object mergers, involve non thermal processes with emissions covering the whole electromagnetic spectrum and the production of non-electromagnetic messengers such as Neutrinos or Gravitational Waves. In order to understand these phenomena it is necessary to study them through a variegated set of instruments each one optimized for a different energy interval. The present effort in Multiwavelength and Multimessenger Astrophysics is focused in improving the instruments sensitivity over the largest energy range possible. I will describe my activity related to the long-standing involvement in High Energy Astrophysics with the Fermi-LAT space mission and the commitment toward the construction of the new facilities ASTRI Mini-Array and Cherenkov Telescope Array Observatory, based on the Imaging Atmospheric Cherenkov Telescope technique. I will also discuss the work for the refurbishment of the Osservatorio di Coloti in Montone (PG).
