Scaling relations of the nucleus and galaxy masses. Top panel: nucleus vs. galaxy mass relation for all nucleated galaxies in the Fornax core region (NGFS dwarfs and ACSFCS sample). Bottom panel: nucleus-to-galaxy mass ratio (﹩{\eta }_{n}={{ \mathcal M }}_{\mathrm{nuc}}/{{ \mathcal M }}_{\mathrm{gal}}﹩) as a function of galaxy mass. Solid lines show the weighted least-squares fits, the numerical values of which are shown in Table 3. Both panels show model predictions for nucleus formation. See the legend and text for more details.
