摘要：Over 300 pulsars are seen to pulse in GeV gamma rays acquired with the Large Area Telescope (LAT) on the Fermi satellite. Many more may be waiting for discovery: of the >2000 LAT sources with no counterpart known at other wavelengths, hundreds are non-variable, with pulsar-like spectral shapes and sky distributions. In addition, population syntheses typically predict as much as twice the current LAT pulsar sample. However, detecting gamma-ray pulsations will be difficult for most of the new ones, whether through blind searches of the gamma-ray data, or using long-term phase-connected rotation ephemeredes for radio pulsars.

I will describe the sample of gamma-ray pulsars in the 3rd LAT Pulsar Catalog, and the ongoing work to transform candidates into discoveries. I will focus on the opportunities that FAST provides to identify the radio-faint, gamma-loud pulsars hidden in the LAT data, highlighting some of the science that further discoveries enable.

Prof. David Smith obtained his Bachelor degree in University of California at Berkeley and Ph.D. degree University of Illinois at Urbana. Working now in Bordeaux Astrophysical Laboratory, he is a senior member of the international collaboration group for the Fermi Gamma-Ray Satellite Large Area Telescope (LAT), with a main research focus on gamma ray pulsars. As the organizer and main author, Fermi-LAT published the second and third gamma ray pulsar source catalogs, providing detailed analysis of over 250 gamma-ray pulsars. This work is one of the important achievements of Fermi-LAT and one of the most important literature on the study of gamma-ray pulsars.
