54 research institutions from twelve countries have signed the agreement for the international R&D collaboration for a future wide field-of-view gamma ray observatory in the southern hemisphere. The aim of the collaboration is to develop, over the next three years, a detailed proposal for the implementation of such an observatory, including site selection and technology choices. The partner countries of the Southern Wide field-of-view Gamma-ray Observatory (SWGO) are Argentina, Brazil, Chile, Czech Republic, Germany, Italy, Mexico, Peru, Portugal, South Korea, the United Kingdom, and the United States of America, creating a worldwide community around the project. In addition, there are 32 supporting scientists from 11 countries.

Spokesperson: Jim Hinton

Vice-spokespersons: Petra Huentemeyer, Ulisses Barres

Countries in which institutes have signed the “Statement of Interest” in SWGO are asked to appoint a national representative to sit on the SWGO Steering Committee. The current membership of the steering committee is:

Adrian Rovero (Argentina) Ronald Shellard (Brazil) Claudio Dib (Chile) Jakub Vicha (Czech Republic) Christopher Van Eldik (Germany) Alessandro de Angelis (Italy, INFN) Marco Tavani (Italy, INAF) Andres Sandoval (Mexico) Jose Bellido Caceres (Peru) Mario Pimenta (Portugal) Jason Lee (South Korea) Jon Lapington (UK) Pat Harding (USA) The Spokesperson and Vice-spokespersons are ex-officio members of the steering committee.
