Thanks to recent technological development, a new generation of cosmic ray experiments have been developed with more sensitivity to study these particles in the primary energy inte…
The young massive stellar cluster Westerlund 1 in rays as seen with H.E.S.S
Lars Mohrmann, Andreas Specovius, Romed Rauth +2
Massive stellar clusters have recently been hypothesised as candidates for the acceleration of hadronic cosmic rays up to PeV energies. Previously, the H.E.S.S. Collaboration has r…
Detection of new Extreme BL Lac objects with H.E.S.S. and Swift XRT
Mathieu de Bony de Lavergne, Tomas Bylund, Manuel Meyer +2
Extreme high synchrotron peaked blazars (EHBLs) are amongst the most powerful accelerators found in nature. Usually the synchrotron peak frequency of an EHBL is above Hz…
Astronomy outreach in Namibia: H.E.S.S. and beyond
Hannah Dalgleish, Heike Prokoph, Sylvia Zhu +6
Astronomy plays a major role in the scientific landscape of Namibia. Because of its excellent sky conditions, Namibia is home to ground-based observatories like the High Energy Spe…
Monitoring the radio galaxy M87 with HAWC
T. Capistrán, D. Avila Rojas, M. M. González +2
Studies of radio galaxies at TeV energies are fascinating because their jets are misaligned concerning our sightline. Thus, it provides us with a unique opportunity to study the st…
