2D stellar kinematics of 48 representative E and S0 galaxies obtained with the SAURON IFS reveal that early-type galaxies appear in two broad flavours, depending on whether they ex…
The Nature of Galactic Bulges from SAURON Absorption Line Strength Maps
Reynier F. Peletier, Jesus Falcon-Barroso, Katia Ganda +10
We discuss SAURON absorption line strength maps of a sample of 24 early-type spirals, mostly Sa. From the Lick indices H, Mg b and Fe 5015 we derive SSP-ages and metallicities.…
