New evidence points to two feeding black holes just 175 parsecs apart lurking in the early universe
Astronomers have discovered two actively feeding supermassive black holes separated by just 175 parsecs in a galaxy observed when the universe was about 2 billion years old. The system, MG B2016+112, is the most compact dual AGN known at this redshift and was posted on the arXiv preprint server on September 25.

AI analysisThis discovery provides strong evidence for the dual active galactic nuclei (AGN) hypothesis in a compact system at high redshift. It supports models that predict galaxy mergers drive gas onto central supermassive black holes, leading to dual AGN formation.
confirmation
- Further observations with near-infrared instruments could confirm or refute the mass estimates and feeding rates of the black holes.
- Future studies may find more such systems at high redshifts, providing insights into galaxy evolution and black hole growth during major mergers.
