标题： A catalog of molecular clouds possibly associated with Galactic infrared bubbles I. The Southern Galactic plane

摘要： 我们对48个可能与银河系红外气泡相关的分子云进行了形态学搜索，这些气泡的角半径为$>1'$，位于南银河平面的$295^\circ \le l\le 350^\circ$和$|b|\le 1^\circ$范围内，由Hanaoka等人(2019)提出。从Mopra南银河平面调查获得的档案数据中，通过$^{12}$CO~$J$~=~1--0线数据，在$(l,b,V_{\rm LSR})$空间中识别出116个分子云，其中$V_{\rm LSR}$是CO线的径向速度。 运动学距离是通过使用银河系最准确的旋转曲线从$V_{\rm LSR}$得出的。 我们还提供了116个分子云的速度弥散、尺寸参数、分子质量以及维里质量的测量结果。 本目录用于研究恒星形成以及分子壳层和空腔的起源，这些可能与红外气泡有关。 分子云的CO线强度图和位置-速度图作为补充数据在线提供。 显示英文摘要

摘要： We have carried out a morphological search for molecular clouds possibly associated with 48 Galactic infrared bubbles with angular radii of $>1'$ in the southern Galactic plane of $295^\circ \le l\le 350^\circ$ and $|b|\le 1^\circ$ presented by Hanaoka et al. (2019). 116 molecular clouds in the $(l,b,V_{\rm LSR})$ space are identified from the archival $^{12}$CO~$J$~=~1--0 line data obtained by the Mopra Southern Galactic plane survey, where $V_{\rm LSR}$ is the CO-line radial velocity. The kinematic distances are derived from $V_{\rm LSR}$ using the most accurate rotation curve of the Milky Way. We also present measurements of velocity dispersion, size parameter, molecular mass, and virial mass of 116 molecular clouds. This catalog is presented to investigate star formation and the origin of molecular shells and cavities, possibly associated with infrared bubbles. CO line intensity maps and position-velocity diagrams of the molecular clouds are available online as supplementary data.
