Logarithmically scaled Hα flux maps from MUSE observations overlaid with contours from the CO(1-0) integrated intensity maps for three new ALMA sources: Centaurus (left panel), RXCJ1539.5−8335 (middle panel), and Abell S1101 (right panel). The co-spatial and morphological correlation between the warm ionized and cold molecular nebulae is clear in these maps. The CO(1-0) emission has been continuum-subtracted and binned from −300 km s−1 to +300 km s−1. The ALMA beam is shown in the upper right corner of each panel. The CO(1-0) contours for Centaurus are: 3σ, 5σ, 7σ, for RXCJ1539.5−8335 are: 3σ, 10σ, 30σ, 50σ, 70σ, etc., and for Abell S1101 are: 3σ, 5σ, 7σ. In the panel showing the data for Centaurus, the small green circle indicates the location of the highest surface brightness Hα emission without any CO emission (see text for details).
