Astronomers Precisely Measure a Black Hole's Accretion Disk

Actively feeding supermassive black holes are known as quasars, and they can outshine all the stars of their host galaxy. Part of their brightness comes from the accretion disk surrounding the black hole, but they're hard to image directly because quasars are so far away. New data from one of the world's largest telescopes has managed this feat, detecting near-infrared emission lines that mark significant regions in the accretion disk in a quasar.

"Astronomers observe the very early Universe running in slow motion

Using cosmic clocks known as 'quasars', a team of astronomers perceive the early Universe running much slower than the present day."

Grundwasserentnahme verschiebt Erdachse jedes Jahr um mehrere Zentimeter

Die stetige Verschiebung der Erdachse verrät, wie viel Grundwasser die Menschheit jährlich entnimmt und in die Ozeane leitet. Es geht um gigantische Mengen.

The 3 million light-year-long structure is anchored by a luminous —a galaxy with an active, at its core. The team believes the filament will eventually evolve into a massive , much like the well-known in the .

Oh, galaxies of power and might
Ruling over stars with their might
You recycle remains of stars that have died
And bring back their beauty and light

Strong by as a probe of the -host relations in the distant Universe: arxiv.org/abs/2306.01042 -> EPFL scientists have managed to weigh, more precisely than any other technique, a galaxy hosting a quasar, thanks to the fact that it acts as a gravitational lens: actu.epfl.ch/news/weigh-a-quas - detection of strong gravitational lensing quasars is expected to multiply with the launch of Euclid this summer.
