Highlight from H.E.S.S. and implication for CTA Era
Abstract
In the 15 years since its construction, the H.E.S.S. gamma-ray observatory has allowed the study of the Very High Energy gamma-ray sky at unprecedented resolutions and sensitivities. During this period H.E.S.S. has discovered a rich zoo of both galactic and extra galactic cosmic ray sources. Recent major discoveries include the TeV emission of Gamma-Ray Burst in the afterglow phase, the first indication of PeV emission in the galactic center, and extended TeV emission along the jets of the nearby radio-galaxy Centaurus A. Some of these discoveries where made possible through very deep exposure coupled with advanced analysis and simulation techniques, which pave the road for the CTA era. In this context, a formal decision on the prolongation of H.E.S.S. for a minimum of three years was made in January 2019, together with an upgrade of the camera of the large telescope, after the upgrade of the H.E.S.S.-I camera in 2017. In its current form, H.E.S.S. is using two camera concepts developed for CTA, namely the NectarCAM and the FlashCam concepts. I will present a summary of the latest H.E.S.S. results, describing the most interesting new observations in the view of the upcoming CTA observatories and their physical interpretation, what recent discoveries imply for the science case of CTA. I will detail the latest and upcoming upgrades and improvements to the H.E.S.S. hardware and data analyses and the future science prospects for the experiment.
