Hα emission of the northern region of Centaurus A with CTIO. We overlaid the H i emission (VLA; white contours), the 250μm emission (Herschel; red contours), the FUV emission (GALEX; black contours) and the radio continuum (ATCA; grey contours; kindly provided by R. Morganti). The white boxes indicate the location of CO detections with SEST (large box) and ATCA (small box), the dashed boxes are the FOV of MUSE data and the white circles are the positions that were observed with ALMA.
