Top panel: moment-0 map of DCO⁺(2–1) (left), N₂D⁺(2–1) (middle), and DCN (2–1) (right). Bottom panels: zooms-in of the three moment-0 maps in the boxes delimited in cyan in the upper panels. The cyan and white ellipses identify the compact cores extracted with CuTEx from the ALMAGAL 7M+TM2 continuum and ALMA Band 4 continuum, respectively. Some of the zoom-in boxes have the intensity multiplied by a factor reported in red in the top right corner of the box, to highlight the emission with respect to the color scale adopted for the full maps.
