Effect of Gamma-Ray Beaming on the Fluxes of Gamma-Ray Pulsars

We study the effect of gamma -ray beaming on gamma -ray emission of the pulsars in a self-sustained outer gap model. In this model, averaged gamma -ray flux is a function of period, magnetic field, magnetic inclination angle and solid angle of gamma -ray beaming for a gamma -ray pulsar. We generate...

Description
Summary:We study the effect of gamma -ray beaming on gamma -ray emission of the pulsars in a self-sustained outer gap model. In this model, averaged gamma -ray flux is a function of period, magnetic field, magnetic inclination angle and solid angle of gamma -ray beaming for a gamma -ray pulsar. We generate a sample of gamma -ray pulsars with their ages less than 106 years by using the Monte Carlo method, and then study the gamma -ray beaming effect. The comparison of distributions of periods, magnetic fields, distances, gamma -ray energy fluxes and period derivatives of the simulated gamma -ray pulsars with those of observed gamma -ray pulsars by the detector EGRET shows that gamma -ray beaming has an important role on the detection of gamma -ray pulsars. Furthermore, possible gamma -ray pulsars observed by the detector GLAST are predicted.
