The origin of Cosmic Rays (CR), more than 100 years after their discovery, remains a "century-old mystery". Therefore the identification of the astronomical sources responsible for the locally measured fluxes of CRs remains one of the highest priorities of the field. Although the discovery of TeV gamma-radiation from SNRs generally supports the SNR paradigm of Galactic CRs, the lack of the...
The recently discovered TeV emission from Gamma-Ray Bursts (GRBs) hints towards a possible hadronic origin of this radiation component. To investigate such scenario, we developed a tailored Monte Carlo (MC) simulation that reproduces the kinematics of photo-hadronic interactions occurring at internal shocks, including the electromagnetic cascade process that the resulting secondary gamma rays...
The Southern Wide-field Gamma-ray Observatory (SWGO) is the proposal for a new ground-based gamma-ray instrument in the Southern Hemisphere, which will use an array of water-Cherenkov based particle detectors to provide continuous monitoring and regular scanning of a large portion of the sky at the very- and ultra-high-energies (VHE and UHE, respectively). At the low energy side, SWGO aims to...
