Modeling high-energy and very-high-energy γ-rays from the Terzan 5 cluster
The Fermi Large Area Telescope (LAT) has recently detected a population of globular clusters (GCs) in highenergy (HE) γ-rays. Their spectral properties and energetics are consistent with cumulative emission from a population ...
Multiwavelength modeling of the globular cluster Terzan 5
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 ...
Glow-in-the-dark globular clusters: modelling their multiwavelength lanterns
(South African Institute of Physics, 2012)
Globular clusters (GCs) are astronomical tapestries embroidered with an abundance of exotic stellar-type objects, including ancient metal-poor stars, planetary nebulae, white dwarfs (WDs), low-mass X-ray binaries (LMXRBs), ...
Modelling the average spectrum expected from a population of gamma-ray globular clusters
Millisecond pulsars occur abundantly in globular clusters. They are expected to be responsible for several spectral components in the radio through γ-ray waveband (e.g., involving synchrotron and inverse Compton emission), ...
The expected very-high-energy flux from a population of globular clusters
Given their old ages, globular clusters are expected to harbour many evolved stellar objects. Their high core densities enhance stellar encounter rates, also facilitating the formation of stellar end products. In particular, ...
