Event Description Posted: September 4, 2003 3:41 pm		NOAO/KPNO--NSO, DEPARTMENT OF ASTRONOMY AND STEWARD OBSERVATORY AND NRAO The University of Arizona <><><><><><><><><><><><><><><><><><> JOINT COLLOQUIUM <><><><><><><><><><><><><><><><><><> presents Dr. Marcin Sawicki of the Herzberg Institute of Astrophysics, National Research Council of Canada who will present a talk entitled Probing for Galaxy Evolution in the Distant Universe ABSTRACT: Advances in technology and technique over the last few years have now made it possible to routinely identify galaxies to look-back times when the Universe was only about a tenth of its present age and a hundredth of its present size. These high-redshift objects are vigorously star-forming and therefore the galaxy population at these early epochs should be undergoing rapid evolution. I will describe two very deep surveys that robustly probe for signs of this evolution within the high redshift galaxy population and I will discuss implications of these studies for our understanding of when and where the Universe formed its stars. on Thursday, October 30, 2003 at 4:00 p.m. in Steward Observatory Lecture Hall-Room N210 Refreshments at 3:30 p.m. in the Lobby
