    • Modelling globular clusters as multi-wavelength diffuse emitters 

      David, Hambeleleni (North-West University (South Africa), 2021)
      The future ground-based Cherenkov Telescope Array (CTA) is expected to detect more than half of the known Galactic globular cluster (GC) population. In this thesis I present results from an emission code that assumes ...
    • Multiwavelength modeling of the globular cluster Terzan 5 

      Büsching, I.; Venter, C.; Kopp, A.; De Jager, O.C.; Clapson, A.C. (ICRC, 2011)
      Diffuse X-ray emission has recently been detected from the globular cluster (GC) Terzan 5, extending out to ~2.5' from the cluster centre. This emission may arise from synchrotron radiation (SR) by energetic leptons being ...
    • A NICER view of spectral and profile evolution for three x-ray-emitting millisecond pulsars 

      Rowan, Dominick M.; Venter, Christo; Ghazi, Zaynab; Lugo, Lauren; Spano, Elizabeth (IOP, 2020)
      We present two years of Neutron star Interior Composition Explorer (NICER) X-ray observations of three energetic rotation-powered millisecond pulsars (MSPs): PSRs B1937+21, B1821−24, and J0218+4232. We fit Gaussians and ...
