DETECTION OF THE PULSAR WIND NEBULA HESS J1825โ137 WITH THE<i>FERMI</i>LARGE AREA TELESCOPE
We announce the discovery of 1 - 100 GeV gamma-ray emission from the archetypal TeV pulsar wind nebula HESS J1825-137 using 20 months of survey data from the Fermi Large Area Telescope (LAT). The gamma-ray emission detected by the LAT is significantly spatially extended, with a best-fit rms extension of โฆ
