Description
Gamma-rays are a high effective tracer of extreme particle acceleration in the cosmos and can also be used to probe fundamental, beyond-standard-model and exotic physics in the present and in the early Universe. In this talk, I will summarise some recent results in gamma-ray astronomy from the current generation of ground-based facilities (e.g. HESS, MAGIC, VERITAS, HAWC, LHAASO) focusing on the multi-GeV to PeV energy regime. These facilities have provided exciting new information on the potential for supernova remnants, supernovae, stellar clusters, pulsar wind nebulae, and accreting systems to accelerate electrons and/or cosmic-ray hadrons. I will also discuss constraints on dark matter properties and some other fundamental physics insights, and conclude with a look at the next generation facilities such as CTA and SWGO.
