Top panel: nucleus vs. host galaxy stellar mass for different subsets of nucleated NGFS galaxies and other galaxies from the literature. The SMBH mass vs. galaxy mass relation from McConnell & Ma (2013) is shown with 1σ and 3σ limits as dashed-line and shaded regions, respectively. Bottom panel: nucleus-to-galaxy mass ratio (﹩{\eta }_{n}={{ \mathcal M }}_{\mathrm{nuc}}/{{ \mathcal M }}_{\mathrm{gal}}﹩) vs. galaxy mass. We approximate the ETG data with a bi-regime fit for which the slopes of the low-mass and high-mass galaxy masses are labeled.
