Discovering DOGS: Dust-Obscured active Galaxies as they Grow

Images of 3 DOG's. The left, middle, and right panels show optical image from HSC, near-infrared image from VIKING, and mid-infrared image from WISE, respectively. The image size is 20 square arcsecond (1 arcsecond is 1/3600 degree). It is clear that DOGs are faint in the optical, but are extremely bright in the infrared.

As they harbor rapidly growing black holes in their centers, these results give us clues for understanding the evolution of galaxies and supermassive black holes. The research group discovered 48 DOGs, and measured how common they are using Subaru Strategic Program with Hyper Suprime-Cam (HSC), a new wide-field camera with a field of view 9X the size of the moon.

How did galaxies form and evolve during t...
