Implications and Applications of Kinematic Galaxy Scaling Relations

Figure 2

Deviation from the FP as a function of for two galaxy samples, ellipticals from van der Marel and van Dokkum [28] (filled red) and S0’s from Bedregal et al. [30] (open blue). As increases that the deviations become systematic and negative, indicating, some dependence on is needed in the scaling relation. The interpretation of this trend is that the FP is not accounting for the dynamical support provided by rotation and that this omission causes larger deviations as the rotational support becomes more important.
