Collision of molecular outflows in the L1448–C system

We present a study of the central zone star-forming region L1448 at 217--230 GHz ($\sim$ 1.3 mm) using ALMA observations. Our focuses on detection proto-stellar molecular outflows and interaction with surrounding medium toward sources L1448--C(N) L1448--C(S). Both exhibit continuum emission, being brightest one. Based its spectral index associated bipolar outflow, emission is most likely to be circumstellar disk. The $^{\rm 12}$CO(J=2$\rightarrow$1) SiO(J= 5$\rightarrow$4) emissions trace outflow jet oriented along northwest-southeast direction. for has wide-open angle V-shape morphology. SiO highly collimated an axial extent comparable emission. There not towards L1448--C(S), but there observations revealed that red-shifted lobes L1448--C(S) are colliding. As result this interaction, L1448-C(S) lobe seems truncated. collision also hinted by where velocity dispersion increases significantly in zone. investigated whether it could possible triggers formation new stars L1448--C system.
