The Remarkable History of Massive Galaxies
Dr. Pieter van Dokkum (Yale)
| In the nearby Universe massive galaxies form a very homogeneous population, as they are almost without exception old, red early-type galaxies. However, observations of distant galaxies have demonstrated that this has not always been the case: about 10 billion years ago massive galaxies showed a great diversity, ranging from large star forming systems to extremely compact quiescent galaxies. I will review these results, and also discuss recent observations of the growth of massive galaxies over the past 10 billion years from the NEWFIRM Medium Band Survey (NMBS) and the newly installed WFC3 camera on HST. |
