by The ultraluminous galaxy is part of a class called "hot Dust-Obscured Galaxies," or "hot DOGs" for short.
Astronomers have discovered a swarm of galaxies orbiting a distant, ultraluminous galaxy that is forming stars at an intense rate, showing that early galaxies grew in dense environments.
Interactions with these satellite galaxies could be feeding the central galaxy — called W0410-0913 — with gas and stars, thus helping it grow to 10 times the size of the Milky Way.
