摘要：Since Fermi was launched in June 2008, the number of known gamma-ray pulsars has increased dramatically: pulsed gamma-ray emission has been detected from more than 60 pulsars by the Large Area Telescope (LAT), the main instrument aboard the Fermi satellite. Among these detections, a population of gamma-ray millisecond pulsars (MSPs) has been seen for the first time. The timing analysis of these rapidly-rotating (rotational period below 30 ms) and relatively faint (a few tens to hundreds of gamma-ray photons per year) objects illustrates the importance of highly-accurate photon time stamps, and the multi-wavelength monitoring of the pulsar rotational period as a function of time. These elements allow the LAT to observe variations in the light curve of MSPs at the 10 ms level, for photons accumulated over a year. I review the observations of MSPs with the Fermi LAT, and discuss the recent discovery of numerous MSPs at the position of unassociated Fermi sources with high time resolution radio observations.
