Probing millisecond pulsar emission geometry using light curves from the Fermi/Large Area Telescope
(IOP Publishing, 2009)
An interesting new high-energy pulsar sub-population is emerging following early discoveries of gamma-ray
millisecond pulsars (MSPs) by the Fermi Large Area Telescope (LAT). We present results from three-dimensional
emission ...
Fermi LAT discovery of extended gamma-ray emission in the direction of supernova remnant W5IC
(IOP Publishing, 2009)
The discovery of bright gamma-ray emission coincident with supernova remnant (SNR) W51C is reported using the Large Area Telescope (LAT) onboard the Fermi Gamma-ray Space Telescope. W51C is a middle-aged remnant (~104 yr) ...

A cosmic-ray positron anisotropy due to two middle-aged, nearby pulsars?
(IOP Publishing, 2008)
Geminga and B0656+14 are the closest pulsars with characteristic ages in the range of 100 kyr to 1 Myr. They both have spin-down powers of the order 3 × 1034 ergs s–1 at present. The winds of these pulsars had most probably ...
Are anomalous cosmic rays the main contribution to the low-energy galactic cosmic ray spectrum?
(IOP Publishing, 2008)
While the high-energy part of the Galactic cosmic ray spectrum is well observed, its nature at energies below
about 1 GeV nucleon-1 is still not known well. Recent in situ measurements made with the Voyager 1 spacecraft
in ...
Longitudinal variation of the pickup-proton-injection efficiency and rate at the heliospheric termination shock
(EDP Sciences, 2008)
Context. Pickup ions are considered to be the seed population of the anomalous cosmic rays. The acceleration of the pickup ions at the solar wind termination shock depends on the efficiency with which they are injected ...
