After almost three years of data taking in sky survey mode, the Fermi -LAT has detected γ-ray emission toward the Tycho’s Supernova Remnant (SNR). The Tycho SNR is among the youngest remnants in the Galaxy, originating from a Type Ia Supernova in AD 1572. The γ-ray integral flux from 400 MeV up to 100 GeV has been measured to be (3.5±1.1stat±0.7syst)×10-9 cm-2s-1 with a photon index of 2.3±0.2stat±0.1syst. A simple model consistent with TeV, X-ray and radio data is sufficient to explain the observed emission as originating from π0-decays as a result of cosmicray acceleration and interaction with the ambient medium.
