| 英文摘要 | We obtain new HI and (13)CO images around supernova remnants Kes 69 and G21.5-0.9. By comparing HI spectra with (13)CO emission spectra, we significantly revise the kinematic distance for Kes 69 to similar to 5.5 kpc, which was 11.2 kpc, and refine the kinematic distance for G21.5-0.9 to similar to 4.8 kpc. For Kes 69, the highest velocity of absorption is similar to 86 km s(-1) and a prominent HI emission feature at similar to 112 km s(-1) has no respective absorption. These new results suggest that Kes 69 is associated with a newly detected extended 1720-MHz OH maser at velocity of similar to 85 km s(-1) that originates from within the bright southern radio shell of Kes 69. For G21.5-0.9, the highest velocity of absorption is similar to 67 km s(-1). The HI absorption spectra of the nearby bright source PMN J1832-1035 and Kes 69 show a common absorption feature at velocity of similar to 69 km s(-1), which is not seen for G21.5-0.9. The resulting velocity of similar to 68 km s(-1) gives the best distance estimate of similar to 4.8 kpc for G21.5-0.9 and associated young pulsar J1833-1034. |
