A research group at the University of California, Berkeley and Columbia University has presented a method for identifying supermassive black holes that were formed through stellar material rather than primordial black holes.
Is there a chance that black holes emerged shortly after the Big Bang?
The largest black holes evolved surprisingly rapidly, appearing less than a billion years after the Big Bang and now burning brightly as quasars from deep within the cosmos. There are now at least 200 supermassive black holes that have ever existed in the universe, according to scientists. So, where did they come from? This is one of the biggest questions in astrophysics.
This question has been asked by scientists for years. Now, a research group at the University of California - Berkeley and Columbia University have provided new insight into this issue through calculations that were recently published in Physical Review Letters. The authors of the study claim that, according to their calculations, the supermassive black holes are "almost entirely" formed within the first billion years after the Big Bang.
Black holes are formed in the death of huge stars, when all of their nuclear fuel has been used up. As a result of the contraction of such a star, a black hole is produced with a mass many times greater than that of the sun. This object attracts surrounding material, gas, and may also merge with other black holes in the future, thus making it more massive.
Black holes that form during the "modern era" (after the Big Bang) are expected to contain a huge amount of information that is preserved in their rotation and charge. As the authors of the study explain, this information will be revealed after applying certain physical laws so-called Hawking radiation – a quantum effect, which causes the black hole to slowly lose mass and ultimately disappear. The discovery allows scientists to study what was happening in the universe before Hawking radiation appeared, effectively "looking back at time zero."
The difficulty, on the other hand, is that all of these procedures take a long time. The first stars and galaxies were just beginning to materialize when the universe was a billion years old. As a result, the formation of supermassive black holes in such a short amount of time is beyond natural astrophysical phenomena.
Some scientists believe that quasars may have developed early enough only if their nuclei were not massive stars, but other things formed under unusual circumstances as a result of density variations in the primordial "soup" immediately following the Big Bang. Primordial black holes with masses of more than one hundred million solar masses are just two examples.
Distinguishing supermassive black holes
Supermassive black holes with masses of millions or even billions of times the mass of our sun are known as "supermassive." These supermassive black holes have been observed throughout the universe. Astrophysicists have suggested paying attention to their surroundings in order to distinguish these supersized monsters from those born from normal stars. Modeling suggests that the most massive black holes formed from "star stuff" have a spherical distribution of surrounding stars.
If the object has not yet had time to absorb the gas that surrounded the original primordial black holes in sufficient quantities, which is to say there were no accretion processes (the fallout of matter onto the black hole), its present initial deuterium, helium, and lithium abundances may be altered. Active galactic nuclei are discussed.
How can scientists verify their ideas?
The study of the host galaxies of these ancient quasars with very large redshifts (that is, those located at the farthest distances from Earth) as well as their surroundings with the most sophisticated telescopes may provide intriguing anomalies and confirm the hypothesis of their formation by a huge number primordial black holes at the start of time.
