Natal molecular cloud of SNR Kes 41. Complete characterisation
Using high-resolution data of the 12CO and 13CO (J = 1-0) line emission from the Mopra Southern Galactic Plane CO Survey in conjunction with neutral hydrogen observations from the Southern Galactic Plane Survey (SGPS) and mid-infrared Spitzer data, we have explored the large-scale environment of the...
