Description

A collaboration of scientists across the globe is currently working on the development of the Southern Wide-field Gamma-ray Observatory (SWGO), a next-generation gamma-ray facility to be constructed in Chile. SWGO will provide wide field-of-view coverage with a high duty cycle for a large portion of the southern sky and complement observations of existing ground-based survey instruments in the Northern Hemisphere and of the Cherenkov Telescope Array which is scheduled to begin science operation in the mid-twenties. Recent discoveries by HAWC and LHAASO such as TeV gamma-ray halos associated with pulsars, >30 TeV gamma-ray emission from binary systems, tens of PeVatron candidates, and multi-TeV gamma-ray emission from a GRB, underscore the need for SWGO in the Southern Hemisphere. In my talk, I will present science drivers of the project and the performance of its baseline design measured against these science benchmarks. I will show the project status and timeline, including progress made toward the construction of SWGO.
