NVSS B182616-161340 , the SIMBAD biblio

The extended radio source G16.2-2.7 is detected as a new previously uncataloged Galactic supernova remnant. Its non-thermal radio spectrum has spectral index α=-0.51, with S_ν(1GHz)=2.08Jy, as being measured with the RATAN-600 radio telescope. The NRAO VLA Sky Survey (NVSS) map at 1.4GHz shows a shell-like bilateral structure. The similar smoothed image from the Effelsberg survey at 2.7GHz is discussed. The angular diameter 17' of a circular shell is fitted to brightness peaks meanwhile the outer diameter D_max=18.4' and the width ΔR=1' are fitted with the model of a spherical optically thin hollow shell. The surface brightness of G16.2-2.7: Σ(1GHz)=(1±0.1)10^–21W/Hz/m²/sr. The peaks in the shell arcs are highly polarized at 1.4GHz.
