We have mapped the protostellar jet HH 211 in 342 GHz continuum, SiO ($J=8-7$), and CO ($J=3-2$) emission at $\sim$ \arcs{1} resolution with the Submillimeter Array (SMA). Thermal dust emission is seen in continuum at the center of the jet,…

We have mapped the SiO J=5-4 line at 217GHz from the HH211 molecular outflow with the Submillimeter Array (SMA). The high resolution map (1.6''x0.9'') shows that the SiO J=5-4 emission comes from the central narrow jet along the outflow…

We present molecular line observations of the protostellar outflow associated with HH270mms1 in the Orion B molecular cloud with ALMA. The 12CO(J = 3 - 2) emissions show that the outflow velocity structure consists of four distinct…
