The Southern Wide-field Gamma-ray Observatory

Project: Research project

Project Details


The Southern Wide-field Gamma-ray Observatory (SWGO) is an astrophysical gamma-ray observatory to be built in South America. It will detect very high-energy light, known as gamma rays, entering the Earth from outer space.

The SWGO Collaboration involves more than 200 scientists from 14 countries. SWGO will be the first high-altitude gamma-ray observatory to provide wide-field coverage of a large portion of the southern sky and will complement the current and future instruments, such as HAWC, LHAASO, and CTA, a worldwide multi-messenger effort, to unveil extreme astrophysical phenomena. It will observe the gamma-ray sky at the highest energies, enabling studies of extreme cosmic objects such as supermassive black holes and remnants of supernova explosions while also probing the nature of dark matter.

SWGO also aims to develop a positive relationship with the host country and the local community.
