Discovery of a Young Gamma-ray Pulsar Associated with an Extended TeV Gamma-ray Source

Since its launch in June 2008, the Large Area Telescope (LAT), onboard the \emph{Fermi} Gamma-ray Space Telescope, has greatly added to our understanding of gamma-ray pulsars. Its fine point spread function and large effective area, combined with the time-differencing method, make it the first gamma-ray instrument capable of discovering a new population of gamma-ray pulsars. We will present the recent discovery of the youngest (~4600 yr) radio-quiet gamma-ray pulsar discovered in a blind frequency search so far: PSR J1022-5746, a pulsar associated with an extended TeV source. We also present multiwavelength observations of the source, including X-ray observations.
