Abstract
We present new images of the low radio surface brightness Supernova Remnant (SNR) G126.2+1.6, based on the 408 MHz and 1420 MHz continuum emission and the HI-line emission data of the Canadian Galactic Plane Survey (CGPS). We find the SNR's flux densities at 408 MHz ( Jy) and 1420 MHz ( Jy) which have been corrected for flux densities from compact sources within the SNR. We list properties of the 19 brightest compact sources within G126.2+1.6 at both 408 MHz and 1420 MHz. The integrated flux density based spectral index () is . The respective T-T plot spectral index is . We also find spatial variations of spectral index within the SNR: 0.2–0.6. HI observations show structures probably associated with the SNR, i.e., features associated with the SNR's southeastern filaments in the radial velocity range of –33 to –42 km s-1, and with its northwestern filaments in –47 to –52 km s-1. This association suggests a distance of 5.6 kpc for SNR G126.2+1.6. The estimated Sedov age for G126.2+1.6 is less than 5 yr.
