GNz7q is a starburst galaxy with a candidate proto-supermassive black hole in the early Universe, at a redshift of 7.1899 ± 0.0005,[2] estimated to have existed only 750 million years after the Big Bang. It was discovered in the Great Observatories Origins Deep Survey-North (GOODS-North) field taken by the Hubble Space Telescope.[3]

The discovery is "the first observation of a rapidly growing black hole in the early universe" and is thought to help explain the growth of supermassive black holes less than a billion years after the Big Bang.[4]

GNz7q lacks various features that are usually observed in typical, very luminous quasars (corresponding to the emission from the accretion disk of the supermassive black hole), which is most likely explained that the central black hole in GN7q is still in a young and less massive phase.
