First pair of feeding supermassive black holes found in a Green Pea galaxy

Astronomers have discovered the first confirmed dual active galactic nucleus in a Green Pea galaxy, revealing two supermassive black holes growing at the same time inside a compact, intensely star-forming system. X-ray observations with Chandra resolved two actively accreting black holes, while Keck spectroscopy confirmed that both belong to the same merging galaxy. The paper outlining the research was submitted to the arXiv preprint server on July 20.
