The nature of galactic bulges from SAURON absorption line strength maps
We discuss SAURON absorption line strength maps of a sample of 24 early-type spirals, mostly Sa. From the Lick indices H, Mgb and Fe 5015 we derive SSP-ages and metallicities. By comparing the scaling relations of Mg b and H and central velocity dispersion with the same relation for the edge-on samp...
