A next-generation ground-based wide field-of-view gamma-ray observatory in the southern hemisphere

Understand

The very-high-energy gamma-ray sky can be surveyed on a daily basis by particle-detector arrays at high (mountain) elevation.

• In the northern hemisphere the survey recently conducted by the HAWC gamma-ray observatory significantly enriched our knowledge about TeV gamma-ray sources.
• In this contribution, we will present an overview on the effort to realise a next-generation gamma-ray survey observatory in the southern hemisphere.
• We will discuss the unique science case for this observatory and how it will be embedded in the multi-messenger and multi-wavelength census of the non-thermal universe.
