The Universe: Solving the mystery of supermassive black holes
Outside of its home galaxy, a quasar can be observed as a brilliant star-like object.
Hubble Space Telescope, ESA, Hubble, and dpa are the sources for this image.
Supermassive black holes called quasars are extremely bright. Astronomers have never been able to understand how it came into being in the early universe
They have now identified the cause. Here, cold gases play a significant role
The earliest supermassive black holes to originate in the cosmos, known as quasars, erupted early one billion years after the Big Bang at the nuclei of freshly created galaxies
But from an astronomical perspective, how can such massive objects with up to a billion solar masses appear in such a brief period of time?
With the use of computer simulations, an international team of researchers has discovered the solution to this question
streams of frigid and turbulent gas condense to create the first black holes, which have masses between ten and one hundred thousand solar masses
In the journal "Nature," scientists explained that these items then serve as "seeds" for the creation of supermassive black holes.
Nearly every galaxy in the universe today has a massive black hole at its core with a mass millions to billions of times that of the Sun
Initially, scientists thought that the number of these supermassive black holes would rise about evenly over the course of cosmic history.
