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.

Webb ziet 3 miljoen lichtjaar lang filament van sterrenstelsels in het vroege heelal

Sterrenstelsels zijn tot strengen geregen in het enorme kosmische web, dat ook enorme leegtes bevat. Met behulp van de Webb Space Telescope hebben astronomen een vroege streng van deze structuur gevonden

Na de Oerknal was het heelal vijf keer langzamer dan nu

De algemene relativiteitstheorie van Albert Einstein zegt dat we het vroege heelal veel langzamer zouden moeten waarnemen dan het huidige. Zo ver in de tijd terugkijken is echter ongrijpbaar gebleken. Astrofysici hebben dat mysterie nu gekraakt door quasars als “klokken

Quasars are the most radiant and powerful objects in the entire universe, but nobody knew how they were triggered—until now.

"Hubble Sees Two Quasars Side by Side in the Early Universe

(...)On April 5th, researchers announced the discovery of a rare double quasar in the early Universe. The two quasars are gravitationally bound, spiraling in towards each other. Their host galaxies are in the process of merging, and the supermassive black holes generating the quasars will also eventually collide and merge."
