The black holes powering #quasars collect matter from their surroundings in a process so energetic that it emits vast amounts of light. So much so that quasars are some of the brightest objects in our sky, meaning even distant ones are visible from Earth.

Like a #celestial beacon, distant #quasars make the brightest light in the #universe. They emit more light than our entire Milky Way #galaxy. The light comes from matter ripped apart as it is swallowed by a supermassive black hole. #Quasar light reveals clues about the large-scale structure of the universe

Quasars Have Always Had Dark Matter Halos

Almost every galaxy ever examined seems to contain a supermassive black hole, and when they're actively feeding on material, they're known as quasars. Astronomers are still working out the connection between quasars and the giant halos of dark matter surrounding their host galaxies. A research team has searched for quasars, seen 13 billion years ago, and the surrounding dark matter halo is always there. These observations could help astronomers understand how supermassive black holes and their host galaxies formed.

Some Galaxies Contain Double Supermassive Black Holes

Astronomers have discovered supermassive black holes at the hearts of most galaxies, but it appears that some of these are binaries. The discovery was made by observing the jets from blazars, actively feeding supermassive black holes that beam directly toward Earth. Some of these jets have been found to wobble slightly, puzzling astronomers. New evidence shows that this wobble, or precession, comes from a binary companion to these supermassive black holes.

How Did Supermassive Black Holes Grow So Quickly, So Early?

Supermassive black holes are a mystery. These monster black holes with millions or even billions of times the mass of the Sun were already present in the first billion years of the age of the Universe. How did they get enough raw material to grow so quickly? A new study suggests that it all comes down to the giant molecular clouds in galaxies that get funneled into the centers of galaxies during mergers, feeding the hungry black holes. The simulations predict they can grow from millions to billions of solar masses within a few hundred million years.
