2MASX J00423991+3017515 is a Seyfert 1 galaxy located in the constellation Andromeda. It is located 1.84 billion light-years from Earth.[1] First discovered by astronomers carrying out a follow-up spectroscopic study on new active galactic nuclei detected by the Burst Alert Telescope (BAT),[2] the galaxy is classfied as a blazar[3] and a quasar.[4] It is also an uncanny active galactic nucleus (AGN).[5]

2MASX J00423991+3017515 is hosted by a disturbed edge-on disk galaxy. It is found interacting with a nearby companion satellite galaxy and currently in an early stages of merging.[5][6] The galaxy is known to present an optical spectrum containing offset broad lines from both the galaxy's absorption and narrow line emission by 1,530 kilometers per second.[7]

A study using broad-band spectral energy distribution also confirms 2MASX J00423991+3017515 is indeed luminous across wavebands, making it fall under the classification of ultraluminous infrared galaxies. The galaxy is also to have shown undergoing a recent wave of star formation which was higher during the past by over 100 Myr of SFR100 = 22 ± 7 MΘ.[5]

Further investigations also showed 2MASX J00423991+3017515 has a misplaced AGN from its center. This hints it might be produced during stages of a merger while exhibiting signs of outflowing wind, or considered a recoiling supermassive black hole caused via ejection from its host galaxy by gravitational waves following the amalgamation of binary progenitor black holes.[6] If the hypothesis is true, this makes 2MASX J00423991+3017515 the strongest known recoiling AGN candidate.[7]
