    • Numerical simulations of composite supernova remnants for small σ pulsar wind nebulae 

      Vorster, M.J.; Ferreira, S.E.S.; De Jager, O.C.; Djannati-Ataï, A. (EDP Sciences, 2013)
      Context. Composite supernova remnants consist of a pulsar wind nebula located inside a shell-type remnant. The presence of a shell has implications on the evolution of the nebula, although the converse is generally not ...

    • Upper limits on very-high-energy gamma-ray emission from core-collapse supernovae observed with H.E.S.S. 

      Abdalla, H.; Arcaro, C.; Backes, M.; Barnard, M.; Böttcher, M.; Chand, T.; Chandra, S.; Ndiyavala, H.; Schutte, H.; Seyffert, A.S.; Van der Walt, D.J.; Van Rensburg, C.; Venter, C.; Wadiasingh, Z.; Zacharias, M.; Zywucka, N.; H.E.S.S. Collaboration (EDP Sciences, 2019)
      Young core-collapse supernovae with dense-wind progenitors may be able to accelerate cosmic-ray hadrons beyond the knee of the cosmic-ray spectrum, and this may result in measurable gamma-ray emission. We searched for ...
