Extending the H.E.S.S. Galactic Plane Survey

Understand

The High Energy Stereoscopic System (H.E.S.S.), located in the Khomas Highlands of Namibia, is an array of four imaging atmospheric-Cherenkov telescopes designed to detect gamma-rays in the very-high-energy (VHE; E > 100 GeV) domain.

• It is an ideal instrument for surveying the Galactic plane in search of new sources of VHE gamma-rays, due to its location in the Southern Hemisphere, its excellent sensitivity, and its large field-of-view.
• The H.E.S.S.
• Galactic Plane Survey (GPS) began in 2004 and initial observations of the Galactic plane resulted in the discovery of numerous VHE gamma-ray emitters.
