Observations of the young supernova remnant RX J1713.7-3946 with the Fermi Large Area Telescope

We present observations of the young supernova remnant (SNR) RXJ1713.7-3946 with the Fermi Large Area Telescope (LAT). We clearly detect a source positionally coincident with the SNR. The source is extended with a best-fit extension of 055 ± 004 matching the size of the non-thermal X-ray and TeV gam...
