摘要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 (10(9) M-circle dot)(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 galaxies(14). Here we report the discovery of an ultraluminous quasar, SDSS J010013.02+280225.8, at redshift z = 6.30. It has an optical and near-infrared luminosity a few times greater than those of previously known z > 6 quasars. On the basis of the deep absorption trough(15) on the blue side of the Lyman-alpha emission line in the spectrum, we estimate the proper size of the ionized proximity zone associated with the quasar to be about 26 million light years, larger than found with other z > 6.1 quasars with lower luminosities(16). We estimate (on the basis of a near-infrared spectrum) that the black hole has a mass of similar to 1.2 x 10(10) M-circle dot, which is consistent with the 1.3 x 10(10) M-circle dot derived by assuming an Eddington-limited accretion rate.
