Description
In this proceeding we look at the relationship between the photometric nuclear properties of early-type galaxies from Hubble Space Telescope imaging and their overall kinematics as observed with the SAURON integral-field spectrograph. We compare the inner slope of their photometric profiles and the Slow/Fast rotator classes, defined by the amplitude of a newly defined λ R parameter, to show that slow rotators tend to be more massive systems and display shallower inner profiles and fast rotators steeper ones. It is important to remark, however, that there is not a one-to-one relationship between the two photometric and kinematic groups.
