Its redshift is z=7.642. This means that we see J0313-1806 as it was at the time when the universe was 670 million years old.
Quasars can emit a thousand times more energy than galaxies like the Milky Way. The source of all activity is accretion disks and jets of supermassive black holes that are in the process of active absorption of matter. J0313-1806 is no exception. In its core there is a black hole with a mass of 1.6 billion solar. Every year it absorbs matter whose mass is equivalent to 25 stars like our Sun.
Such a significant mass of the black hole at the center of O0313-1806, with its such a small age, suggests that it could hardly have been formed as a result of a supernova outbreak. She simply wouldn’t have had enough time to grow to such a huge size. Apparently, another mechanism was involved here in the form of a direct collapse of a huge cloud of cold hydrogen gas.
