AI总结:

ACES-IV发布ALMA中央分子区探索调查的中宽谱线窗口数据,涵盖多种分子跃迁,提供高分辨率观测结果,并探讨连续体与分子线发射的关联性及同位素线比值特征。

摘要:

我们发布了ALMA中央分子区探索调查(ACES)大型计划中的中宽谱线窗口数据,涵盖了SiO(2-1)、SO(2_2-1_1)、H13CO+(1-0)、H13CN(1-0)、HN13C(1-0)以及HC15N (1-0)等分子线跃迁,角分辨率约为2弧秒,速度分辨率为1.7 km/s。两个谱线窗口的完整立方体以及关键数据产品将向社区开放。我们还给出了六条线的积分亮度、峰值亮度、质心速度以及银河经度-速度图。我们简要讨论了连续体与分子线发射之间的形态相关性,以及同位素或同位素omer线对之间的亮度比。我们强调了数据中的一些特征和趋势,这些将在后续的ACES科学论文中进一步跟进。

英文摘要:

We release the intermediate-width spectral window data from the ALMA Central Molecular Zone Exploration Survey (ACES) Large Program, which covers SiO(2-1), SO(2_2-1_1), H13CO+(1-0), H13CN(1-0), HN13C(1-0), and HC15N (1-0), among other molecular line transitions, with an angular resolution of ~2 arcsec and a velocity resolution of 1.7 km s-1 . The full cubes of the two spectral windows as well as the key data products will be available to the community. We also present the integrated brightness, peak brightness, centroid velocity, and Galactic longitude-velocity maps of the six lines. We briefly discuss morphological correlations between the continuum and the molecular line emission, and brightness ratios between pairs of isotopologue or isotopomer lines. We highlight features and trends in the data that will be followed up in upcoming ACES science papers.
