H.E.S.S. Source of the Month
Each month a TeV gamma-ray source investigated with the H.E.S.S. telescopes is featured. See also the pages on Astrophysics with H.E.S.S.: The Nonthermal Universe with an overview of the physics and the source types.
The Vela Pulsar – the most Highly Energetic Clock
November 2023 Pulsars, progeny of supernova explosions, are among the most fascinating beasts in the cosmic zoo. They are rapidly rotating objects exhibiting magnetic field intensities many orders of magnitude
HESS J1645−455 – A gem on the ring?
October 2023 The brightest source of gamma-ray emission in any energy band is the Milky Way. It dominates the all-sky maps obtained with scanning or hemispheric detectors operating in space
The identity crisis of the blazar PKS 1510-089
August 2023 Blazars are the most abundant sources in the VHE sky and attract a lot of attention by changing their brightness on all time scales that have been probed
