 At the time of the determination of the size of the black hole, in 2016, it was found to be unusual in its location in relation to the galaxy population of the region.Previously, extremely large black holes were only found in the hearts of large dense rich clusters, the galaxy group for which NGC 1600 is found is only an average galaxy group and not a rich cluster.This discovery could signify previously unknown populations of very large black holes, and that black hole growth models may be incorrect or incomplete.
