SDSS J010013.02 + 280225.8
SDSS J010013.02 + 280225.8 (shortened SDSS J0100 + 2802) is a quasar from the catalog of the Sloan Digital Sky Survey (SDSS). Due to the great distance, the state 875 million years after the Big Bang is observed from Earth . Its currently observable light was therefore on the move for 12.8 billion years. The cosmological redshift is z = 6.30. With twelve billion solar masses , the quasar contains one of the most massive black holes from the early phase of the universe. It is also the brightest of all known quasars from this period. Its luminosity is roughly 420 trillion times that of the sun .
discovery
SDSS J0100 + 2802 was discovered by an international team of researchers and described in 2015. The team is led by astronomer Xue-Bing Wu from Beijing University . They discovered the astronomical objects with the help of the Lijiang telescope at the Yunnan Astronomical Observatory in China . Since this quasar comes from a time when the universe was less than 900 million years old, all of the discoveries it have made provide insights into the growth of galaxies and black holes in the young universe.
