A Deep View on the Early Universe: Extreme Makeovers & Overweight Galaxies
Mariska Kriek (Princeton University)
Recent studies have demonstrated that the galaxy population at z=2-3 shares
characteristics with today's galaxies: massive galaxies are predominantly
red, a color-density relation was already in place, and massive, quiescent
galaxies form a red sequence in color-mass space. However, the high-redshift
universe far from resembles the local universe. Massive galaxies at z~2.5 do
not seem to represent a Hubble sequence as their structures and morphologies
are different from their local analogs. Furthermore, the space density of
massive galaxies still has to grow significantly, implying that many local
early-type galaxies assemble or form at later times. In my talk I will
discuss these similarities and differences, and their implications for our
understanding of the physical processes that govern galaxy formation and
evolution.
