Abstract : The High Energy Stereoscopic System (H.E.S.S.) is a gamma-ray observatory located in the highlands of Namibia, operational since 2002. It has undergone several upgrades to maintain scientific relevance and withstand the desert environment. H.E.S.S. houses CT5, the largest gamma-ray telescope, which has been equipped since 2019 with FlashCAM, a new prototype camera designed to...
Pulsars are rapidly rotating neutron stars for which we detect pulsed emission. Pulsars have been detected from radio (more than 3000 sources detected) to gamma-rays (300 sources detected in 3PC).
In the last 2 decades, Imaging Atmospheric Cherenkov Telescopes (IACTs), such as H.E.S.S., MAGIC or VERITAS, have drastically enhanced the very high energy (VHE) astronomy, with several hundreds of...
The project that I will describe concerns the study of the gamma-ray source VER J0521+211, an active galactic nucleus of the blazar subclass, using gamma-ray data from the Large Area Telescope (LAT) on board the Fermi Gamma-ray Space Telescope and the Very Energetic Radiation Imaging Telescope Array System (VERITAS). I will first give an overview of the properties of this object and then I...
