James Webb detects anomalous black holes in the early universe

Astronomers using the James Webb Space Telescope have obtained evidence confirming that black holes in the early universe grew faster than their host galaxies. Researchers studied the COLA1 and NEPLA4 galaxies, observed just 800 million years after the Big Bang. It was found that the black holes at their centers have an abnormally large mass relative to the surrounding star systems. This is reported by Ixbt.com .

Spectroscopic analysis showed that each of these black holes has a mass of approximately 170–190 million solar masses. This figure is 400–800 times larger than that of black holes in modern galaxies. Scientists believe these objects represent an intermediate stage between primordial black holes and bright quasars.

Modeling results indicated that these black holes began accreting matter at an extremely high rate 180–270 million years after the Big Bang. Star formation in the galaxies, however, became active much later, approximately 750 million years later. This contradicts the classical theory that a galaxy and its central black hole evolve simultaneously.

Currently, the activity of the black holes in COLA1 and NEPLA4 has decreased, while the process of star formation in the galaxies is intensifying. Future observations using tools like the Extremely Large Telescope and Subaru Telescope will help understand the early history of the universe and how black holes grew so rapidly.
