"Obesity in the Universe: Why Did Early-Type Galaxies Grow in Size?" Once considered the simplest class of galaxy to model and explain, the assembly
history of early type galaxies still presents many puzzles. Spectroscopic observations show that
the most massive examples completed their star formation earlier than that in their
less massive counterparts, in apparent contradiction to popularly-held hierarchical
models. Hubble observations have also revealed that many of the most massive
early types seen at high redshift are much more compact than their present-day
equivalents. This suggests they somehow expanded in size without growing
significantly in mass. Clearly, early type galaxies still have a lot to tell us about
galaxy formation and assembly. I will reveal the progress being made with new
spectroscopic and Hubble data (....but don't promise to solve all the puzzles). California Institute of Technology host: Paul Shapiro |
