AGILE observations of Supernova Remnants

Abstract

We will review the crucial AGILE gamma-ray SNR observations focusing on the evidence of hadronic cosmic-ray acceleration that has been obtained so far. We discuss data on SNR IC443, W28 and W44. We show that in all cases a consistent model of hadronic acceleration and interaction with gaseous surroundings can be used to successfully explain the quite complex morphology and spectral characteristics of the sources. AGILE, with its crucially important sensitivity near 100 MeV, is equipped to prove the existence of pi-zero emission.
