The Southern Wide-field Gamma-ray Observatory: A Next-generation Ground-based Survey Instrument for Gamma-ray Astronomy
Prof. Ulisses Barres, CBPF
12 de março – 5ª. feira – 17h – sala L774
The Southern Wide-field Gamma-ray Observatory (SWGO) is the international project to build the next-generation gamma-ray facility, and the first of its kind in the Southern Hemisphere. SWGO will be constructed at 4.800 m in altitude in Chile, and will provide wide field-of-view coverage with a high duty cycle for a large portion of the southern sky, complementing existing ground-based survey instruments in the Northern Hemisphere and expanding the capabilities of the Cherenkov Telescope Array towards the ultra-high-energies. The observatory is expected to start construction as early as 2026, and to be completed in its first phase by 2030. Recent results by HAWC and LHAASO such as TeV gamma-ray halos associated with pulsars, >30 TeV gamma-ray emission from binary systems, the discovered of several tens of PeVatron candidates in the Galaxy, as well as multi-TeV gamma-ray emission from GRBs, are some of the science questions motivating SWGO, and which underscore the need for an observatory of its kind in the Southern Hemisphere. In this talk we will present the science drivers of the project as well as the performance of its baseline design. We will also discuss the project status and timeline, including recent progress made towards the construction of the observatory, emphasising the South American role and contributions.
