ALMA CO(2−1) integrated intensity map of NGC 5643 in gray scale, produced from the natural-weight data cube on a linear scale. The black contours are the CO(2−1) emission on a logarithmic scale. The first contour lies at 8σ and the last contour at 8.7 × 10⁻¹⁸ erg s⁻¹ cm² beam⁻¹. Filled blue and green contours are the MUSE [O III]λ5007 Å and Hα emission maps (see Sect. 4), respectively. Red and orange regions correspond to the outflow and nuclear spiral selected zones, respectively. North is up and east is left, and offsets are measured relative to the AGN.
