Discovery of diffuse gamma-ray emission in the vicinity of G172.8+1.5: An old supernova remnant with different turbulence properties
Yuan Li, Gwenael Giacinti, Siming Liu
We report the detection of high-energy -ray emission in the vicinity of G172.8+1.5, which is debated as a Supernova remnant (SNR) or an ionized hydrogen (H) region.…
Discovery of diffuse -ray emission in the vicinity of G213.0-0.6: Supernova remnant versus massive star-forming region
Yuan Li, Gwenael Giacinti, Siming Liu
We report the discovery of high-energy -ray emission in the vicinity of G213.0-0.6, which is debated as a supernova remnant (SNR) or an ionized hydrogen (H) region.…
-Cygni supernova remnant in -rays: signatures of trapped and escaped Cosmic Rays
Yuan Li, Gwenael Giacinti, Siming Liu +1
We reanalyze 15 years of data recorded by the Fermi Large Area Telescope in a region around supernova remnant (SNR) -Cygni from 100 MeV to 1 TeV, and find that the spectra of tw…
Evidence for hybrid gamma-ray emission from the supernova remnant G150.3+4.5
Yuan Li, Siming Liu, Gwenael Giacinti
The supernova remnant (SNR) G150.3+4.5 was first identified in radio, exhibiting a hard GeV spectrum and a radius. Radio observations revealed a bright arc with an…
