| Abstract: | We have carried out CO J = 2-1 and CO J = 3-2 observations toward Tycho's supernova remnant(SNR) using the KOSMA 3m-telescope.From these observations,we identified three molecular clouds(MCs) around the SNR.The small cloud in the southwest was discovered for the first time.In the north and east,two MCs(Cloud A and Cloud B) adjacent in space display a bow-shaped morphology,and have broad emission lines,which provide some direct evidences of the SNR-MCs interaction.The MCs are revealed at-69--59 km s-1,coinci... |
