| 英文摘要 | We present the initial data for the (J = 3 -> 2) transition of (CO)-C-13 obtained from the central molecular zone (CMZ) of the Milky Way as part of the CO Heterodyne Inner Milky Way Plane Survey 2 (CHIMPS2). Covering 359 degrees <= l <= 1 degrees and |b| <= 0.5 degrees with an angular resolution of 19 arcsec, velocity resolution of 1 km s(-1), and rms Delta T-A(& lowast;) = 0.59K at these resolutions, our observations unveil the complex structure of the CMZ molecular gas in improved detail. Complemented by the (CO)-C-12 CHIMPS2 data, we estimate a median optical depth of tau(13 )= 0.087. The preliminary analysis yields a median (CO)-C-13 column-density range equal to N((CO)-C-13) = 2-5 x 10(18)cm(-2), median H-2 column density equal to N(H-2) = 4x10(22)cm(-2) to 1x10(23)cm(-2). We derive N(H-2)-based total mass estimates of M(H-2) = 2-6x10(7)M(circle dot), in agreement with previous studies. We analyse the relationship between the integrated intensity of (CO)-C-13 and the surface density of compact sources identified by Herschel Hi-GAL, and find that younger Hi-GAL sources detected at 500 mu m but not at 70 mu m follow the dense gas of the CMZ more closely than those that are bright at 70 mu m. The latter, actively star-forming sources appear to be more associated with material in the foreground spiral arms |
