This review summarizes the current state of ground-based very-high-energy gamma-ray astronomy, highlighting over 70 sources, implications for the non-thermal universe, and future instrument advancements covering a broad energy range.
Contribution
It provides a comprehensive overview of VHE gamma-ray sources and discusses upcoming instruments that will significantly enhance observational capabilities.
Findings
Over 70 VHE gamma-ray sources identified.
Implications for understanding the non-thermal universe.
Next-generation instruments will cover 10 GeV to 10^5 GeV with improved sensitivity.
Abstract
The high-lights of ground-based very-high-energy (VHE, GeV) gamma-ray astronomy are reviewed. The summary covers both Galactic and extra-galactic sources. A total of at least 70 sources are currently known. Implications for our understanding of the non-thermal Universe are discussed. The next generation of ground based gamma-ray instruments aims to cover the entire accessible energy range from as low as GeV up to GeV and to improve the sensitivity by an order of magnitude in comparison with current instruments.
