Galaxy Nuclei, Galaxy Outskirts

I will talk about two different aspects of massive galaxy evolution.
First, I will discuss the assembly of elliptical galaxies based on
high signal to noise spectra beyond the effective radius taken with an
integral-field spectrograph. The stars in the outskirts of these
galaxies are enriched in alpha elements but have low metallicity,
similar to thick disk stars in our galaxy.  We suggest that these
stars were accreted from small galaxies that formed early and had a
truncated star formation history.  Second, I will discuss supermassive
black hole scaling relations, and what they may tell us about the
coevolution of black holes and galaxies.  I will end with tantalizing
new clues about the lifetimes of sub-pc supermassive black hole
binaries.
