ABSTRACT
The Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope (formerly GLAST), with its improved sensitivity relative to previous generation gamma-ray telescopes, is significantly increasing the number of known GeV gamma-ray sources in the sky, including pulsars. In addition to detecting gamma-ray emission from known radio pulsars, it is now possible to successfully perform blind searches for pulsars on the gamma-ray data alone. Fermi has uncovered a new population of potentially radio-quiet (Geminga-like) pulsars. The Milagro Gamma-Ray Observatory (2000-2008) consisted of a water-Cerenkov detector sensitive to gamma rays above 100 GeV, overlapping and extending the energy range of Fermi. Of the brightest Galactic Fermi sources in the field of view of Milagro, 14 are observed at Milagro at greater than 3 sigma. Of these 14 sources, 9 are pulsars and 9 have never been detected at TeV energies. In this talk, I will discuss the discovery of these gamma-ray pulsars with Fermi, including the search techniques involved, as well as the observations of these pulsars at the highest energies with Milagro.
