Meet Arjun Dey, Ph.D.

Arjun Dey, PhD, Astronomer, National Optical Astronomy Observatory, Tucson, Arizona; Research Fellow (2013-2014), Radcliffe Institute for Advanced Study at Harvard University.

Dr. Dey is an expert on galaxy evolution, high redshift galaxies, and large-scale structures in the universe. His many discoveries include one of the earliest galaxies in the universe.

Dr. Dey appeared on SftPublic's Contemporary Science Issues and Innovations program April 15, 2014 to discuss Massive Galaxies: Where and How They Form. He explained how astrophysicists, with advanced techniques and powerful telescopes, penetrate the most remote areas of the universe to analyze massive galaxies. And he described how large-scale structures in the cosmos provide information about the distribution and the nature of dark matter -and clues about dark energy.
