SOFIA FIFI-LS continuum-subtracted spectra toward the two dense cores in Gy 3–7: HIGALBM224.6079–1.0065 (source “A”) and HIGALBM224.6128–1.0013 (source “B”). The emission is extracted within a beam size of 20″ indicated by black circles in the right panel of Fig. 2. Vertical lines show the laboratory wavelengths of the detected lines. Spectra of the [OI] line at 63 μm are multiplied by a factor of 0.2 and those of the CO 14–13 line by a factor of 0.6 to better illustrate the line detections.
