Descripción
In this proceedings paper we make use of the two-dimensional stellar
kinematics of a representative sample of E and S0 galaxies obtained with
the SAURON integral-field spectrograph to reveal that early-type
galaxies appear in two broad flavors, depending on whether they exhibit
clear large-scale rotation or not. We measure the level of rotation via
a new parameter (λR) and use it as a basis for a new
kinematic classification that separates early-type galaxies into slow
and fast rotators. With the aid of broad-band imaging we will reinforce
this finding by comparing our kinematic results to the photometric
properties of these two classes.
