SMSS J215728.21-360215.1
SMSS J215728.21-360215.1 , commonly known as J2157-3602 , is one of the fastest growing black holes and one of the most powerful quasars known to exist as of 2021[update] . The quasar is located at redshift 4.75,[1] corresponding to a comoving distance of 2.5× 1010 ly from Earth and to a light-travel distance of 1.25× 1010 ly . It was discovered with the SkyMapper telescope at Australian National University 's Siding Spring Observatory , announced in May 2018. It has an intrinsic bolometric luminosity of 6.95× 1014 L ☉ ( 2.66× 1041 W ) and an absolute magnitude of -32.36.[1] [3] [4] [5] [6]
In July 2020 the black hole associated with the quasar was reported to be 34 billion solar masses , based on a study published in Monthly Notices of the Royal Astronomical Society .[7] [8] [2]
