Modelling of highly extended Gamma-ray emission around the Geminga Pulsar as detected with H.E.S.S

A. M. W. Mitchell, S. Caroff

Geminga is an enigmatic radio-quiet gamma-ray pulsar located at a mere 250 pc distance from Earth. Extended very-high-energy gamma-ray emission around the pulsar has been detected…

A Tale of 3 Dwarfs: No Extreme Cluster Formation in Extreme Star-Forming Galaxies

Rupali Chandar, Miranda Caputo, Angus Mok +8

Nearly all current simulations predict that outcomes of the star formation process, such as the fraction of stars that form in bound clusters (Gamma), depend on the intensity of st…

Combined dark matter searches towards dwarf spheroidal galaxies with Fermi-LAT, HAWC, H.E.S.S., MAGIC, and VERITAS

Celine Armand, Eric Charles, Mattia di Mauro +13

Cosmological and astrophysical observations suggest that 85\% of the total matter of the Universe is made of Dark Matter (DM). However, its nature remains one of the most challengi…

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…
