The SAURON Survey - The stellar populations of early-type galaxies

Galaxy Formation

What do we know?

Field vs Cluster

What do we know? Clues from intermediate redshift

What would we like to know?

Two complementary approaches

The SAURON Sample

Models: age, metallicity & [Mg/Fe]

SAURON - Indices

NGC 3384 S0 (cluster)

Line-strength maps – N5813

Emission line subtraction

NGC 4365 (E3) – Line-strength

NGC 4365 – Age, [M/H]

NGC 4150 (S0) : post-starburst

Metal production

Why abundance ratios?

NGC 4150 – [Mg/Fe]

NGC 4365 – [Mg/Fe]

NGC 5813 – [Mg/Fe]

NGC 4406 – [Mg/Fe]
