TL;DR
This study used ALMA to identify 27 filamentary structures in the 50km/s molecular cloud at the Galactic Center, demonstrating the ubiquity of filaments in this region for the first time.
Contribution
First filament-finding analysis in the Galactic Center, revealing widespread molecular cloud filaments with ALMA observations.
Findings
Identified 27 filaments in the 50km/s molecular cloud
Filaments are common in the Galactic Center region
First application of DisPerSE for filament detection in this area
Abstract
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.
