Astronomers have discovered the largest known black hole, which consumes an amount of gas and dust equivalent to the mass of the Sun every day.
This was reported by the scientific portal ScienceAlert.
According to researchers, the mass of the celestial body discovered at the center of the quasar galaxy J0529-4351 is estimated at approximately 17 billion solar masses. Her growth is so fast that she is approaching the limit of how much material she can absorb.
Astronomy experts have determined that the discovered black hole is growing at a rate of approximately 370 solar masses per year. This represents the maximum stable feeding rate of black holes, known as the Eddington limit.
With a further increase in the rate of feeding of the black hole, the matter will begin to emit such intense radiation that the radiation pressure will begin to push the matter out of the gravitational influence of the black hole until it is outside its gravitational field.
At the moment, scientists have still not been able to establish the exact mechanisms of formation of supermassive black holes. However, a study of the quasar J0529-4351 may shed light on this issue. It should be noted that a quasar is a very bright active galactic nucleus whose radiation is powered by a supermassive black hole at its center.
J0529-4351 is a quasar discovered in the Cosmic Noon, approximately 1.5 billion years after the Big Bang. This is a very early period in the history of the Universe.
Earlier, Cursor wrote that researchers, whose findings were published in the journal Monthly Notices of the Royal Astronomical Society, discovered that the supermassive black hole at the center of our galaxy rotates at such a high speed that it bends space-time, making it oval , like a rugby ball.
