3D distribution of galaxies in Centaurus association, using supergalactic coordinates centered on Cen A. Two subgroups centered around M 83 (large dot on the left) and Cen A (large dot on the right) are clearly visible. In the Cen A subgroup, NGC 4945 is also indicated with a large dot. The dotted line indicates our line-of-sight toward Cen A, originating from the SGY_cSGZ_c plane. The literature distance values are taken from Tully et al. (2015), Müller et al. (2018b), and Crnojević et al. (2019).
