To Build an Elliptical Galaxy
I discuss two essential aspects of elliptical galaxy formation: how
they get their stars, and how they lose their gas. For the former, I
use integral-field observations of local massive galaxies to study the
stellar populations and kinematics of stars at large radius, to
understand the origin of the size growth of elliptical galaxies. Then
I focus on black hole feedback as a means of clearing gas from massive
galaxies. I show that luminous obscured quasars have ubiquitous,
round ionized outflows with very high gas dispersions of nearly 1000
km/s out to 20 kpc. Finally, if time permits I will combine these two
themes and present our recent search for sub-pc supermassive black
hole binaries.
