H.E.S.S. (High Energy Stereoscopic System) is a hybrid array of five Imaging Atmospheric Cherenkov Telescopes observing the very high energy gamma-ray sky. In the past decade, this experiment has significantly contributed to the field of ground-based gamma-ray astronomy. In particular, the H.E.S.S. Galactic plane survey (HGPS), conducted from 2004 to...

Fast radio bursts are millisecond-duration radio beacons from a so-far unidentified class of extragalactic sources first discovered about a decade ago. Their inferred distances, and therefore radio burst energies, challenge models based on known source classes, while their inferred rates suggest they are fairly common. While most sources have so-far...
