WebApr 4, 2024 · The observations revealed that the red-shifted lobes of the CO (J=2 1) outflows of L1448--C (N) and L1448--C (S) are colliding. As a result of this interaction, the L1448-C (S) lobe seems to be truncated. The collision of the molecular outflows is also hinted by the SiO (J= 5 4) emission, where the velocity dispersion increases significantly … WebMar 4, 2024 · G351.16+0.70 is a relatively well-studied High Mass Star Forming Region with at least two main bipolar outflow structures originating from an OB embedded star and multiple IR cores. Using high-resolution and large bandwidth SMA observations, we studied its molecular content to probe the emission of iCOMs which could be related to the …
