Galactic Gamma-Ray Astronomy with the Southern Gamma-Ray Survey Observatory
On behalf of the SGSO Consortium.
The field of Very-High-Energy (VHE, E>100 GeV) gamma-ray astronomy is entering an era of precision measurements. Over the last decade, innovations in instrumentation have led to a drastically improved understanding of the most energetic objects in the Universe. New results by the High Altitude Water Cherenkov Observatory (HAWC) have shown the unique insights that large-field-of-view survey instruments like HAWC can provide to the field. The recent 2HWC catalog and other publications have revealed gamma-ray emission from several large extended sources such as TeV halos sourrounding pulsar-wind nebulae. Synergies between ground- and space-based survey and pointing instruments have already led to the identification of several new sources and source candidates.
In this presentation, we will explore the potential of the Southern Gamma-Ray Survey Observatory (SGSO) for Galactic gamma-ray astronomy. SGSO is a proposed next-generation, ground-based, wide-field-of-view TeV gamma-ray observatory. It will be sensitive to gamma rays in the energy range from 100 GeV to hundreds of TeV. In particular, we will discuss further study of TeV halos, the search for large extended structures such as possible counterparts of the Fermi bubbles at TeV energies, gamma-ray emission from Molecular clouds, and the search for galactic transients.
