“Forming the Brightest Galaxies in the Universe” by Desika Narayanan, Ph.D., Assistant Professor, Department of Astronomy, University of Florida

Abstract:  Detected at far-infrared wavelengths, "submillimeter galaxies" are the brightest and most heavily star-forming galaxies in the Universe.  Understanding their origin has been confounding for theorists since their discovery almost 20 years ago.  In this talk, I will review the observational and theoretical background of this field, and present a new computational model suggesting how these enigmatic systems can form naturally from hierarchical growth.  Key to this model are the physics of star formation on very small scales.
