Discovering Dust-Obscured Active Galaxies as They Grow
August 26, 2015
A group of researchers from Ehime University etc. has performed an extensive search for Dust Obscured Galaxies (DOGs) using data obtained from the Subaru Strategic Program with Hyper Suprime-Cam (HSC). The very wide-field of view of HSC is ideal for searching this rare and important class of galaxies. The research group discovered 48 DOGs, and has measured how common they are. Since DOGs are thought to harbor a rapidly growing black hole in their centers, these results give us clues for understanding the evolution of galaxies and supermassive black holes...
