Distribution of dust continuum emission toward Gy 3–7. Left: continuum map of Gy 3–7 at 70 μm observed with Herschel/PACS. Red “+” and blue “×” symbols refer to the 70 μm continuum peaks, adopted as the positions for the dense cores A and B in the subsequent analysis. Circles show the positions of HIGALBM224.6079–1.0065 and HIGALBM224.6128–1.0013 cores from the Herschel/Hi-GAL catalog (Elia et al. 2021). Right: map of the H₂ column density (N_H2). Black circles with the beam size of 20″ indicate the extract regions of the SOFIA FIFI-LS spectra toward the two dense cores A and B (see more in Sect. 3.1). White contours in each map show the continuum at 70 μm, with contour levels at 5, 10, 40, 80, 400, and 800 mJy arcsec⁻².
