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 ...
Constraints on the lepton content of PWN from the local CR positron spectrum
Geminga is a nearby pulsar with an age of 3.42×105 yr and a spindown power of 3.2×1034 erg/s at present. B0656+14 has comparable spindown power, with an age of 1.11×105 yr and a distance of 290 pc. The winds of these ...
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), ...
