Descripción
We simulate the characteristics of the Galactic population of radio and
gamma-ray pulsars using Monte Carlo techniques. At birth, neutron stars
are spatially distributed with supernova-kick velocities in the Galactic
disk and randomly dispersed in age back to 109 years. They
are evolved in the Galactic gravitational potential to the present time.
From a radio luminosity model, the radio flux is filtered through a
selected set of radio-survey parameters. Using the features of recent
polar cap acceleration models invoking space-charge-limited flow, a
pulsar death region further attenuates the population and radio-loud
pulsars are assigned gamma-ray luminosities. In this paper, we will
discuss detailed comparisons between the characteristics of calculated
pulsars and those of observed pulsars. We will present predictions of
the number of radio-loud, gamma-ray pulsars observed by EGRET and GLAST.
