We take advantage of the first data from the Sydney-AAO Multi-object Integral field Galaxy Survey to investigate the relation between the kinematics of gas and stars, and stellar mass in a comprehensive sample of nearby galaxies. We find that all 235 objects in our sample, regardless of their morphology, lie on a tight relation linking stellar mass (M∗) to internal velocity quantified by the S<inf>0.5</inf> parameter, which combines the contribution of both dispersion (σ) and rotational...[Show more]
