Descrizione
The Southern-hemisphere Wide-field Gamma-ray Observatory (SWGO) will be the first instrument of its kind in the southern hemisphere. It consists of thousands of Cherenkov water detectors arranged in a circular area of $\sim1$ km$^{2}$. Currently under design phase, SWGO will be a wide-field-of-view and $100\%$ duty cycle facility to detect gamma rays in the $100$ GeV to tens of PeV energy range. Also, there is significant potential for cosmic ray studies including anisotropy. SWGO will be built in the Atacama Astronomical Park, Chile, at an altitude of 4770 m.a.s.l., allowing us to map the galactic center, transient, multiwavelength, and multimessenger phenomena. This facility will highly complement the Cherenkov Telescope Array Observatory (CTAO) which is ready to start the building phase near in the Atacama desert. Both instruments represent the next generation of gamma ray experiments, and are planned to make major advances in the field. In this work, I will present a general review of the current SWGO status and its scientific potential for fundamental physics such as Lorentz invariance violation testability. In addition, I will show a brief study on the muon content in extensive air showers at the PeV scale.
