Abstract
We present ALMA observations of the molecular line transition C18O(1–0) in the north region of the molecular cloud G14.225-0.506. We aim to demonstrate the existence of filamentary structures that channel the flow of gas towards the embedded stellar cluster. We found that the spectral profile of the region has two main velocity components, the more intense and therefore dominant one is around ∼ 20 kms−1, and it is associated with the cloud. We identified 20 relevant structures within the molecular cloud all of them dominated by non-thermal motions indicative of the presence of turbulence, rotation and/or accretion. We selected five structures near to the stellar cluster and studied their kinematics. The results show an accretion of gas towards the cluster and two distinct regions with blueshift (north) and redshift (south).
