Title: The Universe at z=2-4: New Insights into Galaxy Formation and Evolution
Date: Wednesday, May 9th, 2012
Time: 11:30
Venue: Villa Bazzoni

Abstract: In the past five years, our understanding of the galaxy population at redshift between 2 and 4 has improved significantly, thanks to the increasing ability to construct comprehensive snapshots (in time) from z=4 (when the universe was ~1.5 billion years old) to z=2 (when it was ~3.5 billion years old). As these 2 billion years of the cosmic history represent a key epoch in the buildup and evolution of galaxies, studies of the properties of galaxies at these redshifts provide important clues on the physical processes at work during galaxy formation and evolution. I will summarize our current knowledge of the galaxy population at z=2-4, with an emphasis on the new results from the NEWFIRM Medium-Band Survey, a large NOAO/Yale program which uses medium band-width filters in the near-infrared to obtain well-sampled spectral energy distributions and high-quality photometric redshifts at z>1.5 over 0.5 square degree. I will conclude by outlining on-going experiments/surveys which will take our understanding of galaxy formation and evolution to the next level.
