摘要:

我们目前的观测50平方度的Mopra一氧化碳(CO)调查的南银河平面,涵盖银河系的$l = 300$ - $350^\circ$和纬度$|b| \le 0.5^\circ$。这些数据是以0.6角分的空间分辨率和0.1 km/s的光谱分辨率拍摄的,提供了在109-115 GHz $J = 1$-0跃迁的$^{12}$ CO、$^{13}$ CO、C $^{18}$ O和C $^{17}$ O中南银道面分子云和气体的前所未有的视图。我们提出了一系列的速度集成的地图,光谱和位置-速度图,说明银河系的手臂结构和跟踪质量的顺序$\sim$ 10 $^{6}$ M $_{\odot}$每平方度,并包括一个初步的目录C $^{18}$ O块位于$l=330$ - $340^\circ$之间。这些数据与调查的噪声统计信息一起可以从Mopra CO网站、PASA数据存储和Harvard Dataverse(doi:10.7910/DVN/LH 3BDN)中检索。

英文摘要:

We present observations of fifty square degrees of the Mopra carbon monoxide (CO) survey of the Southern Galactic Plane, covering Galactic longitudes $l = 300$-$350^\circ$ and latitudes $|b| \le 0.5^\circ$. These data have been taken at 0.6 arcminute spatial resolution and 0.1 km/s spectral resolution, providing an unprecedented view of the molecular clouds and gas of the Southern Galactic Plane in the 109-115 GHz $J = 1$-0 transitions of $^{12}$CO, $^{13}$CO, C$^{18}$O and C$^{17}$O. We present a series of velocity-integrated maps, spectra and position-velocity plots that illustrate Galactic arm structures and trace masses on the order of $\sim$10$^{6}$ M$_{\odot}$ per square degree; and include a preliminary catalogue of C$^{18}$O clumps located between $l=330$-$340^\circ$. Together with information about the noise statistics of the survey these data can be retrieved from the Mopra CO website, the PASA data store and the Harvard Dataverse (doi:10.7910/DVN/LH3BDN ).
