Left: CSO intensity gradient magnitudes at 350 μm in units of Jybeam−1 arcsec−1 (color scale) overlaid on the CSO dust continuum emission at 350 μm (contours, Busquet et al. 2016; Lin et al. 2017a). Contour levels are 3, 6, 9, and 12 times the rms noise of 80 mJy beam−1. The yellow star depicts the position of IRAS 18153−1651. The white circle in the bottom left corner depicts the CSO beam size (~10″). Hub-N, Hub-S, and the Hub-C candidate identified by Chen et al. (2019) are labeled. Right: close-up images of the intensity gradient toward Hub-N (top panel) and Hub-S (bottom panel) overlaid on the SMA1.3 mm dust continuum emission (black and white contours) at an angular resolution of ~ 1′′.5 (Busquet et al. 2016). Contour levels range from 12σ to 30σ in steps of 6σ, and from 30σ to 60σ in steps of 15σ, in Hub-N and similar but starting from 6σ in Hub-S, where σ is the rms of the map, ~1 mJy beam−1. White segments show the CSO B-field orientation, similar to Fig. 1. White star (right upper panel), red pentagon, black diamond, and yellow square (right bottom panel) depict MM1a, MM7a, MM4, and MM5a cores, respectively.
