j_t − M_* plane for the ePN.S galaxies (left) and comparison with previous works (right). Left panel: total sAM of the ePN.S galaxies as a function of their stellar mass. For clarity we only show the mass-weighted j_t, mass values data-points. Solid lines show the power-law fit to j_t, mass vs. M_*; dashed lines show the fit to the mass-weighted j_t, light vs. M_*; dotted lines show the fit to the values corrected for IMF gradients j_{t, mass + IMF} − M_{*, var IMF} using the mean mass excess profiles from Bernardi et al. (2023) as discussed in Sect. 4.2.2. Green lines refer to S0 galaxies, purple lines refer to the ellipticals. Right panel: dashed green and purple lines show the power-law fits to the ePN.S lenticulars and elliptical galaxies, respectively, as in the left panel. Dotted black lines show the j_t − M_* relations for different bulge fractions β as derived by Fall & Romanowsky (2018). Dashed and solid black lines show the fits of Romanowsky & Fall (2012) and Fall & Romanowsky (2013) to their sample of S0s and ellipticals. In both panels, the magenta line shows the results of Di Teodoro et al. (2023) on their samples of spiral galaxies.
