Identifying the brightest Galactic globular clusters for future observations by H.E.S.S. and CTA

Ndiyavala, Hambeleleni; Krüger, Petrus Paulus; Venter, Christo (Oxford Univ Press, 2018)

We present results from an emission code that assumes millisecond pulsars to be sources of relativistic particles in globular clusters (GCs) and models the resulting spectral energy distribution of Galactic GCs due to ...
A population of gamma-ray emitting globular clusters seen with the Fermi Large Area Telescope

Abdo, A.A.; Venter, C.; Ackermann, M.; Ajello, M.; Baldini, L.; Fermi LAT (EDP Sciences, 2010)

Context. Globular clusters with their large populations of millisecond pulsars (MSPs) are believed to be potential emitters of high-energy gamma-ray emission. The observation of this emission provides a powerful tool to ...
Search for very-high-energy y-ray emission from galactic globular clusters with H.E.S.S

Abramowski, A.; Casanova, C.; Krüger, P.P.; Pekeur, N.W.; Sheidaei, F.; Venter, C.; Vorster, M.; H.E.S.S. Collaboration (EDP Sciences, 2013)

Context. Globular clusters (GCs) are established emitters of high-energy (HE, 100MeV < E < 100 GeV) γ-ray radiation which could originate from the cumulative emission of the numerous millisecond pulsars (msPSRs) in the ...
