Introduction

The study of non-thermal processes in the Universe, the most violent ones, has been pioneered by Very High Energy (VHE, E \(\gtrsim \) 100 GeV) astrophysics. VHE gamma-rays serve also for delving into fundamental physics beyond the standard model of particle physics. The major portion of the matter content of the universe, approximately 85%, is composed of Dark Matter (DM), the enigmatic nature of which continues to confound scientists. One of the leading explanations for DM involves non-baryonic massive particles undergoing, beyond gravitational interaction, weak force interaction with standard matter. These are termed weakly interacting massive particles (WIMPs). If WIMPs are massive enough, they can undergo self-annihilation generating TeV gamma-rays in dense regions of the cosmos. The Galactic Center (GC), along with its immediate surroundings, stands out as a prime location for detecting signals from DM annihilation.
