Astronomers from Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences and their collaborators have found five Green Pea (GP) galaxies with double-peaked narrow lines among nearly 1,550 GP galaxies. These objects may originate from dual active galactic nuclei (AGN) mergers, potentially revealing the co-evolutionary characteristics of a special class of high-mass galaxies and supermassive black holes.
