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), ...
Modeling high-energy and very-high-energy γ-rays from the Terzan 5 cluster
(Fermi, 2011)
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
(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 ...
Constraints on the lepton content of PWN from the local CR positron spectrum
(ICRC, 2008)
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 ...
