Distribution of “feedback clumps” and “non-feedback clumps” classified under the 8 μm threshold 1.1 × 10⁻⁶ W/(m⁻²⋅ sr). The gray background image represents the integrated intensity map of ¹³CO, while the black contour lines depict the above mentioned 8 μm flux intensity. Red contours denote ¹³CO-identified clumps that are classified as “feedback clumps”, while Green contours show all other ¹³CO-identified clumps, the so-called “non-feedback clumps.” The yellow stars and blue crosses correspond to OB stars (Roman-Lopes et al. 2019) and HMYSOs (Lumsden et al. 2013), respectively.
