17 Jul 2019 | | Abstract: | We describe plans for the development of the Southern Wide-field Gamma-ray
Observatory (SWGO), a next-generation instrument with sensitivity to the
very-high-energy (VHE) band to be constructed in the Southern Hemisphere. SWGO
will provide wide-field coverage of a large portion of the southern sky,
effectively complementing current and future instruments in the global
multi-messenger effort to understand extreme astrophysical phenomena throughout
the universe. A detailed description of science topics addressed by SWGO is
available in the science case white paper [1]. The development of SWGO will
draw on extensive experience within the community in designing, constructing,
and successfully operating wide-field instruments using observations of
extensive air showers. The detector will consist of a compact inner array of
particle detection units surrounded by a sparser outer array. A key advantage
of the design of SWGO is that it can be constructed using current, already
proven technology. We estimate a construction cost of 54M USD and a cost of
7.5M USD for 5 years of operation, with an anticipated US contribution of 20M
USD ensuring that the US will be a driving force for the SWGO effort. The
recently formed SWGO collaboration will conduct site selection and detector
optimization studies prior to construction, with full operations foreseen to
begin in 2026. Throughout this document, references to science white papers
submitted to the Astro2020 Decadal Survey with particular relevance to the key
science goals of SWGO, which include unveiling Galactic particle accelerators
[2-10], exploring the dynamic universe [11-21], and probing physics beyond the
Standard Model [22-25], are highlighted in red boldface. | | Source: | arXiv, 1907.7737 | | Services: | Forum | Review | PDF | Favorites | |
