Top: two-color image toward G20.0-0.2. In green: radio continuum emission at 20 cm. In red: emission of the ¹³CO integrated between 64.3 and 68.6 km s^-1 (contour levels are 10.0, 14.6, and 19.0 K km s^-1). The blue rectangle indicates the area shown in the adjacent figure. Bottom: Spitzer-IRAC 8 μm band. The red contours are the ¹³CO emission and the cyan contours are the 1.1 mm continuum emission from the BGPS (contour levels are 0.1 and 0.5 Jy/Beam). The most intense molecular emission (traced by the 19.0 K km s^-1 contour level) shows a spatial correspondence with the millimeter source BGPS G19.926-0.257 and the dark cloud SDC G19.928-0.257.
