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 resolutions and sensitivities which were never before possible. During this period H.E.S.S. has discovered a rich zoo of both galactic and extra galactic source classes, made measurements of the galactic cosmic ray spectrum and placed limits on fundamental physical processes. A summary of the latest H.E.S.S. results for these source classes has been presented at the conference, describing the most interesting new observations and their physical interpretation. Additionally the latest upgrades and improvements to the H.E.S.S. hardware and data analyses, and the future science prospects for the experiment have been described.
Highlights
The H.E.S.S. array, inaugurated 15 years ago, revolutionized our view on the Very High Energy (VHE) gamma-ray sky with more than 100 sources discovered
A second phase of the experiment started in 2012, with the installation of the fifth, largest telescope (28 m diameter), allowing the threshold to be lowered from ∼ 100 GeV down to ∼ 20 GeV and bridge the gap with space instruments such as Fermi-LAT
The field of VHE γ-ray astronomy is experiencing a kind of phase-transition, where single discoveries tend to have less importance and where population studies and detailed analysis of sources of specific interest are opening new fields
Summary
The H.E.S.S. array, inaugurated 15 years ago, revolutionized our view on the Very High Energy (VHE) gamma-ray sky with more than 100 sources discovered. The field of VHE γ-ray astronomy is experiencing a kind of phase-transition, where single discoveries tend to have less importance and where population studies and detailed analysis of sources of specific interest are opening new fields. In this context, a new paradigm of simulation (Section 2.3) is emerging and opening new science capabilities, with unprecedented resolution and understanding of the instrument. Maps and tables from the HPGS were released, for the first time, as FITS file to allow better exploitation by the community
