Population synthesis of radio and gamma-ray millisecond pulsars from the Galactic disk
Sarah A. Story, Peter L. Gonthier, Alice K. Harding
We present results of a population synthesis of millisecond pulsars from the Galactic disk. Excluding globular clusters, we model the spatial distribution of millisecond pulsars by…
The Geminga Fraction
Alice K. Harding, Isabelle A. Grenier, Peter L. Gonthier
Radio-quiet gamma-ray pulsars like Geminga may account for a number of the unidentified EGRET sources in the Galaxy. The number of Geminga-like pulsars is very sensitive to the geo…
Population statistics study of radio and gamma-ray pulsars in the Galactic plane
Peter L. Gonthier, Sarah A. Story, Brian D. Clow +1
We present results of our pulsar population synthesis of ordinary isolated and millisecond pulsars in the Galactic plane. Over the past several years, a program has been developed…
Developing radio beam geometry and luminosity models of pulsars
P. L. Gonthier, S. A. Story, B. M. Giacherio +2
Our recent studies of pulsar population statistics suggest that improvements of radio and gamma-ray beam geometry and luminosity models require further refinement. The goal of this…
Spin-Dependent Cyclotron Decay Rates in Strong Magnetic Fields
Matthew G. Baring, Peter L. Gonthier, Alice K. Harding
Cyclotron decay and absorption rates have been well studied in the literature, focusing primarily on spectral, angular and polarization dependence. Astrophysical applications usual…
The role of beam geometry in population statistics and pulse profiles of radio and gamma-ray pulsars
Peter L. Gonthier, Robert Van Guilder, Alice K. Harding
We present results of a pulsar population synthesis study that incorporates a number of recent developments and some significant improvements over our previous study. We have inclu…
Pulsar Populations and Unidentified Gamma-Ray Sources
A. K. Harding, P. L. Gonthier, I. A. Grenier +1
The EGRET telescope on the Compton Gamma-Ray Observatory detected over 200 sources and the majority of these are still unidentified. At least three subpopulations of EGRET sources…
Galactic populations of radio and gamma-ray pulsars in the polar cap model
Peter L. Gonthier, Michelle S. Ouellette, Joel Berrier +2
We simulate the characteristics of the Galactic population of radio and -ray pulsars using Monte Carlo techniques. At birth, neutron stars are spatially distributed in the Galac…
Compton Scattering in Ultra-Strong Magnetic Fields: Numerical and Analytical Behavior in the Relativistic Regime
Peter L. Gonthier, Alice K. Harding, Matthew G. Baring +2
This paper explores the effects of strong magnetic fields on the Compton scattering of relativistic electrons. Recent studies of upscattering and energy loss by relativistic electr…
The Attenuation of Gamma-Ray Emission in Strongly-Magnetized Pulsars
Matthew G. Baring, Alice K. Harding, Peter L. Gonthier
Gamma-rays from pulsars can be efficiently attenuated in their magnetospheres via the mechanism of single-photon pair production and also the exotic QED process of photon splitting…
Photon Splitting Cascades in Gamma-Ray Pulsars and the Spectrum of PSR1509-58
Alice K. Harding, Matthew G. Baring, Peter L. Gonthier
Magnetic photon splitting, a QED process that becomes important only in magnetic fields approaching the quantum critical value, B_cr = 4.41 X 10^13 Gauss, is investigated as a mech…
