An ultra-luminous quasar with a twelve-billion-solar-mass black hole at redshift 6.30
So far, roughly 40 quasars with redshifts greater than z = 6 have been discovered ¹⁻⁸. Each quasar contains a black hole with a mass of about one billion solar masses (10⁹Μʘ)², ⁶, ⁷, ⁹⁻¹³. The existence of such black holes when the Universe was less than one billion years old presents substantial challenges to theories of the formation and growth of black holes and the coevolution of black holes and galaxies¹⁴. Here we report the discovery of an ultraluminous quasar, SDSS J010013.02+280225.8,...[Show more]
