Cosmic-ray positrons from millisecond pulsars
(IOP Publishing, 2015)
Observations by the Fermi Large Area Telescope of γ-ray millisecond pulsar (MSP) light curves imply copious pair
production in their magnetospheres, and not exclusively in those of younger pulsars. Such pair cascades may ...
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 ...
Multi-wavelength modeling of globular clusters: the millisecond pulsar scenario
(IOP Publishing, 2013)
The potentially large number of millisecond pulsars (MSPs) in globular cluster (GC) cores makes these parent objects ideal laboratories for studying the collective properties of an ensemble of MSPs. Such a population is ...
Constraining a general-relativistic frame-dragging model for pulsed radiation from a population of millisecond pulsars in 47 Tucanae using GLAST LAT
(IOP Publications, 2008)
Although only 22 millisecond pulsars (MSPs) are currently known to exist in the globular cluster (GC) 47 Tucanae, this cluster may harbor 30-60 MSPs, or even up to ∼200. In this Letter, we model the pulsed curvature radiation ...
High-energy pulsar models: developments and new questions
(Wiley, 2014)
The past few years have seen a major advance in observational knowledge of high-energy (HE) pulsars. The Fermi Large
Area Telescope (LAT) and AGILE have increased the number of known γ-ray pulsars by an order of magnitude, ...
Constraints on the emission geometries and spin evolution of gamma-ray millisecond pulsars
(IOP Publishing, 2014)
Millisecond pulsars (MSPs) are a growing class of gamma-ray emitters. Pulsed gamma-ray signals have been
detected from more than 40 MSPs with the Fermi Large Area Telescope (LAT). The wider radio beams and more
compact ...
Search for very-high-energy y-ray emission from galactic globular clusters with H.E.S.S
(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 ...
