>The largest black hole so far known has been established to be 34 billion times the mass of our Sun, this Supermassive Black Hole (SMBH) J2157 is the fastest-growing black hole and largest quasar observed to date.
>The team’s study, which appeared in The Monthly Notices of the Royal Astronomical Society at the end of June 2020, was led by Dr. Christopher A. Onken – the operations manager of the SkyMapper telescope. He was joined by researchers from the Research School of Astronomy and Astrophysics (RSAA) and the Center for Gravitational Astrophysics (CGA) at ANU, as well as the European Southern Observatory (ESO) and Steward Observatory.
>J2157 is the brightest quasar observed in the known Universe to date. It is visible 12.5 billion light-years from Earth.
>“The black hole’s mass is also about 8,000 times bigger than the black hole in the center of the Milky Way. If the Milky Way’s black hole wanted to grow that fat, it would have to swallow two-thirds of all the stars in our Galaxy. We’re seeing it at a time when the universe was only 1.2 billion years old, less than 10 percent of its current age. It’s the biggest black hole that’s been weighed in this early period of the Universe.”
>The fact that it was the fastest-growing SMBH in the Universe just 1.2 billion years after the Big Bang was nothing short of astounding. Dr Fuyan Bian, a staff astronomer at the European Southern Observatory, said:
>“We knew we were onto a very massive black hole when we realized its fast growth rate. How much black holes can swallow depends on how much mass they already have. So, for this one to be devouring matter at such a high rate, we thought it could become a new record holder. And now we know.”
