Finalizing the Design of the Southern Wide-field Gamma-ray Observatory

Key Points

The southern wide-field gamma-ray observatory aims to facilitate precise observations of the gamma-ray sky.
SWGO, located in Chile, is designed to cover a substantial area and improve upon prior observatories like CTA and LHAASO.
Utilizing double-layered water cherenkov detectors, SWGO will enhance gamma-ray observation capabilities across a wide energy range.
Preliminary results show promising instrument response functions, underscoring the effectiveness of the SWGO setup.

Abstract

The Southern Wide-field Gamma-ray Observatory (SWGO) is a next-generation experiment and offers precise wide-field observations of the southern gamma-ray sky. SWGO will be located in Pampa la Bola, Chile, at an altitude of 4770 m, covering an area of 1 km² and complementing CTAO and LHAASO. By leveraging double-layered Water Cherenkov Detectors, the SWGO design will facilitate gamma-ray observations from 100s of GeV to the PeV scale. This contribution will discuss recent advancements in optimizing the SWGO array layout and detector design. Furthermore, we present the preliminary Instrument Response Functions of the observatory, demonstrating the effectiveness of the SWGO approach.
