Developing gamma-ray pulsar simulation tools for GLAST

Pulsars are among the most intriguing sources in the gamma-ray Universe and their high-energy emission remains today quite mysterious. The Gamma-ray Large Area Space Telescope (GLAST) will study the pulsar gamma-ray emission in great detail and will discover a great number of new gamma-ray pulsars. Here are presented the latest developments of the tools that have been created for producing accurate simulations of gamma-ray pulsars emission. The main simulator is called PulsarSpectrum and can reproduce gamma-ray emission with great detail, taking also into account advanced timing effects, e.g. period increase with time, barycentric corrections and higher-order timing noise currently under development. Detailed spectral features can also be simulated with PulsarSpectrum, such as phase-dependent spectra. A suite of ancillary tools have also been built to provide a realistic pulsar population with related timing solutions. Anyway PulsarSpectrum can also simulate pulsar populations coming from external synthesis codes. All these tools are presently used within the GLAST collaboration for testing the LAT Science Analysis Environment tools and for better study of LAT capabilities for pulsar science
