论文摘要
这项研究开发了一种自动识别程序，用于在高度拥挤的区域的光谱线数据立方体中具有较大速度宽度的紧凑型云。该过程应用于使用James Clerk Maxwell望远镜获得的CO J = 3-2线数据，以识别184个高速散布紧凑型云（HVCC），这是我们星系中心分子区域中发现的一类特殊的分子云。在-1.4°<l <+2.0°，-0.25°<b <+0.25°的区域中，HVCC的列表显示了其物理参数，CO J = 3-2/j = 1-0强度比和形态分类。因此，该列表提供了一些有趣的来源，这些资源可能是由与点状的大型对象，局部能量事件或云到云碰撞的相遇所驱动的。
This study developed an automated identification procedure for compact clouds with broad velocity widths in the spectral line data cubes of highly crowded regions. The procedure was applied to the CO J=3-2 line data, obtained using the James Clerk Maxwell Telescope, to identify 184 high velocity dispersion compact clouds (HVCCs), which is a category of peculiar molecular clouds found in the central molecular zone of our galaxy. A list of HVCCs in the area -1.4°<l<+2.0°, -0.25°<b<+0.25° was presented with their physical parameters, CO J=3-2/J=1-0 intensity ratios, and morphological classifications. Consequently, the list provides several intriguing sources that may have been driven by encounters with point-like massive objects, local energetic events, or cloud-to-cloud collisions.
