'A Deep View on the Early Universe: Extreme Makeovers & Overweight Galaxies'

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.
