I will present the emission-line fluxes and kinematics of 48
representative elliptical and lenticular galaxies obtained with the
SAURON integral-field spectrograph. Hb, [OIII], and [NI] emission lines were
measured using a new procedure that simultaneously fits both the stellar
spectrum and the emission lines. Emission is detected in 75% of our
sample galaxies, and comes in a variety of resolved spatial distributions,
kinematic behaviours, and line-ratios.
I will discuss the implications of these findings for our understanding
of the origin and fate the ionised-gas, of the ionising mechanisms at
work in early-type galaxies, and of the level of star formation in these
systems.
