Baryonic effects on galactic rotation curves. The blue solid line is the average VrotVh relation in a ΛCDM universe (same as in Fig. 4). The red triangles represent galaxies from a set of hydrodynamic simulations which include efficient baryonic feedback (Governato et al. 2012; Brooks & Zolotov 2014; Christensen et al. 2014). Simulated low-velocity galaxies fall in the same region of the VrotVh diagram as the actual dwarfs plotted in Fig. 6. This demonstrates that baryonic modifications of the galaxies’ rotation curves do not significantly affect the simplified analysis performed in this work.
