American astrophysicists from the Massachusetts Institute of Technology found large black holes that could not be explained in the existing quasar when the universe was less than a billion years. This area, which overshads all galaxies in the brightness, aroused doubt the modern theories of the formation of black holes. The study was published at the following address Portal Expected scientific materials Arxiv.
With a red shift Z≳6 and the billions of suns in the quasars, super -breastfeeding black holes represent a serious puzzle. According to standard accumulation models, they did not have enough time to gradually obtain such dimensions with suction (one billion years after the big explosion).
It is even more surprising that the new data shows: These Kuasars were active in a very short time – less than a million years and some are only 1000 years old. This contradicts ideas about a long and sustainable growth process.
The team proposed several alternative formation mechanisms: Fusion of black holes, strong substance jets (jets) and episodic super -eeddingon accumulation accelerated growth (absorption of substance at a rate higher than the theoretical limit).
The researchers used Muse Specstrograph on a very large telescope in Chile to examine the abnormal small areas of close proximity. Lyman-alfa, which could demonstrate the first stages of Quasar’s activity, was paid particular attention to the uncertainty of huge hydrogen clouds.
The analysis has shown that the observed super solid black holes are indeed in the oldest stages of the active absorption of matter. This means that they have reached their enormous dimensions before the beginning of the intensive accumulation requiring the revision of existing models.
Experts, “These objects are challenging our understanding of growth processes in the early universe. Ultra -mass black holes that we do not know seems to have mechanisms for the formation of the formation,” he said.
