Super-bright ‘DOG’ galaxy fed by surrounding small galaxies

Astronomers have discovered a swarm of galaxies orbiting a distant, ultra-bright galaxy that is forming stars at an intense rate, showing that early galaxies grew in dense environments.

Interactions with these satellites galaxies The central galaxy – called W0410-0913 – can feed gas and stars, helping it grow to 10 times its size. Milky Way. However, the researchers found that these galaxies do not cause as much chaos at W0410-0913 as scientists previously thought.
