Baseline Design for a Next Generation Wide-Field-of-View Very-High-Energy Gamma-Ray Observatory

Understand

The TeV gamma ray sky is observable by recording footprints of extensive air showers with an array of particle detectors.

• In the northern hemisphere there are currently two projects employing this technique: The HAWC gamma ray observatory which is currently operational in Mexico and LHAASO in the Sichuan region in China which is currently under development.
• In the southern hemisphere several efforts are currently ongoing to investigate the feasibility of a similar observatory at very high altitude sites in the Andes.
• The science case for such an observatory should be complementary to the science to be performed by the future Cherenkov Telescope Array.
