This image of ULAS J1120+0641, a very distant quasar powered by a black hole with a mass two billion times that of the Sun, was created from images taken from surveys made by both the Sloan Digital Sky Survey and the UKIRT Infrared Deep Sky Survey. The quasar appears as a faint red dot close to the centre. This quasar was the most distant one known from 2011 until 2017, and is seen as it was just 770 million years after the Big Bang. Its black hole is so massive it poses a challenge to modern cosmological theories of black hole growth and formation.

Out in the extremities of the distant Universe, the earliest quasars can be found.

HE0435-1223, located in the centre of this wide-field image, is among the five best lensed quasars discovered to date, where the lensing phenomenon magnifies the light from distant objecst. This effect enables us to see quasars whose light was emitted when the Universe was less than 10% of its current age. The foreground galaxy creates four almost evenly distributed images of the distant quasar around it.

Supermassive black holes at the centers of young galaxies accelerate matter to tremendous speeds, causing them to emit jets of radiation.
.
While distant host galaxies for quasars and active galactic nuclei can often be imaged in visible/infrared light, the jets themselves and the surrounding emission is best viewed in both the X-ray and the radio, as illustrated here for the galaxy Hercules A.

What we observe enables us to reconstruct the mass of the central black hole, and explore the ultra-distant Universe.

The farther away we look, the closer in time we’re seeing towards the Big Bang. The current record-holder for quasars comes from a time when the Universe was just 690 million years old.

Recently, a new black hole, J1342+0928, was discovered to originate from 13.1 billion years ago: when the Universe was 690 million years old, just 5% of its current age.

As viewed with our most powerful telescopes, such as Hubble, advances in camera technology and imaging techniques have enabled us to better probe and understand the physics and properties of distant quasars, including their central black hole’s properties.

It has a mass of 800 million Suns, an exceedingly high figure for such early times.

This artist’s rendering shows a galaxy being cleared of interstellar gas, the building blocks of new stars. Winds driven by a central black hole are responsible for this, and may be at the heart of what’s driving this active ultra-distant galaxy behind this newly discovered quasar.

Even if black holes formed from the very first stars, they’d have to accrete matter and grow at the maximum rate possible — the Eddington limit — to reach this size so rapidly.
.
The active galaxy IRAS F11119+3257 shows, when viewed up close, outflows that may be consistent with a major merger. Supermassive black holes may only be visible when they’re ‘turned on’ by an active feeding mechanism, explaining why we can see these ultra-distant black holes at all.

Fortunately, other methods may also grow a supermassive black hole.
.
When new bursts of star formation occur, enormous quantities of massive stars are created.
.
The visible/near-IR photos from Hubble show a massive star, about 25 times the mass of the Sun, that has winked out of existence, with no supernova or other explanation. Direct collapse is the only reasonable candidate explanation, demonstrating that not all stars need to go supernova or experience a stellar cataclysm to form a black hole.

.
These can either directly collapse or go supernova, creating large numbers of massive black holes which then merge and grow.
.
Simulations of various gas-rich processes, such as galaxy mergers, indicate that the formation of direct collapse black holes should be possible. A combination of direct collapse, supernovae, and merging stars and stellar remnants could produce a young black hole this massive. Complementarily, present LIGO results indicate that black holes merge every 5 minutes somewhere in the Universe.

Only ~20 black holes this large should exist so early in the Universe.

An ultra-distant quasar showing plenty of evidence for a supermassive black hole at its center. How these black holes got so massive so quickly is a topic of contentious scientific debate, but may have an answer that fits within our standard theories. We are uncertain whether that’s true or not at this juncture.

This picture of ULAS J1120+ 0641, an extremely remote quasar powered by a great void with a mass 2 billion times that of the Sun, was produced from images drawn from studies made by both the Sloan Digital Sky Study and the UKIRT Infrared Deep Sky Study. The quasar looks like a faint red dot near to the centre. This quasar was the most remote one understood from2011 till2017, and is viewed as it was simply770 million years after the Big Bang. Its great void is so huge it presents a difficulty to modern-day cosmological theories of great void development and development.

HE0435-(****************************************************************************************** ), situated in the centre of this wide-field image, is amongst the 5 finest lensed quasars found to date, where the lensing phenomenon amplifies the light from remote objecst. This result allows us to see quasars whose light was discharged when deep space was less than 10% of its existing age. The foreground galaxy develops 4 practically equally dispersed pictures of the remote quasar around it.

Supermassive great voids at the centers of young galaxies speed up matter to significant speeds, triggering them to release jets of radiation.
While remote host galaxies for quasars and active stellar nuclei can frequently be imaged in visible/infrared light, the jets themselves and the surrounding emission is finest seen in both the X-ray and the radio, as shown here for the galaxy Hercules A.

What we observe allows us to rebuild the mass of the main great void, and check out the ultra-distant Universe.
