Discovery of Diffuse γ-Ray Emission in the Vicinity of G213.0-0.6: Supernova Remnant versus the Massive Star-forming Region

We report the discovery of high-energy γ -ray emission in the vicinity of G213.0-0.6, which is debated as a supernova remnant (SNR) or an ionized hydrogen (H _II ) region. Using 16 yr Pass 8 data from Fermi Large Area Telescope, we found three extended sources with different photon spectra in this r...
