New evidence points to two feeding black holes just 175 parsecs apart lurking in the early universe

Astronomers have found two actively feeding supermassive black holes separated by just 175 parsecs (570 light-years) in a galaxy seen when the universe was only about 2 billion years old. The system, MG B2016+112, lies at a redshift of 3.273 and is the most compact dual AGN known at this redshift. The study was posted to the arXiv preprint server on Sept. 25.
