Middle panel: overlay of the 343 GHz continuum emission (green contours) on the integrated intensity (moment 0) map (colors) of SiO (8–7). The contour levels are the same as in Fig. 2. The red circles indicate the positions of the 5 compact centimeter sources detected by Cyganowski et al. (2011). Lower and upper panels: SiO (8–7) spectra toward selected positions in the G35.03 core. The vertical dashed line indicates the V_LSR.
