ALMA银河系中心50 km/s分子云视图

摘要:

我们用ALMA对银河系中心50 km/s分子云进行了观测,寻找了分子云的结构。在CS J=2-1的发射线通道图中,我们成功地识别了27个分子云细丝使用DisPerSE算法。这是在银河系中心区域进行的首次“发现”尝试。这些分子云细丝强烈地暗示了分子云细丝在银河系中心区域的分子云中也是普遍存在的。

英文摘要:

We have observed the Galactic Center 50km/s molecular cloud (50MC) with ALMA to search for filamentary structures. In the CS J=2-1 emission line channel maps, we succeeded in identifying 27 molecular cloud filaments using the DisPerSE algorithm. This is the first attempt of "filament-finding" in the Galactic Center Region. These molecular cloud filaments strongly suggest that the molecular cloud filaments are also ubiquitous in the molecular clouds of the Galactic Center Region.
