Descripción
The Southern Wide-field Gamma-ray Observatory (SWGO) will be a next generation ground array experiment probing the Southern sky in search of gamma-ray sources from the Galactic plane. The collaboration has chosen as primary site Pampa la Bola in the Atacama Astronomical Park (Chile) at 4770 m above the sea level. SWGO will detect the secondary particles through Water Cherenkov Detectors (WCD). The experiment will have a wide field-of-view and almost 100% duty cycle. A central dense core of WCDs will make SWGO capable of studying events of energy as low as 100 GeV, but the recent results of both HAWC and LHAASO (both in the northern hemisphere) have opened the discussion of the PeV range and the science case of PeVatrons. SWGO will be the first ground-based experiment of its kind operating in the TeV to PeV range in the southern hemisphere. The collaboration is evaluating multiple options for the outer array. In this contribution we will show the performance of the current candidate design of SWGO from 30 TeV up to PeV scale, discussing both energy (15%) and angular resolution (0.15 deg).
