Markarian 463 (Mrk 463) known as UGC 8850, is a galaxy merger located in the constellation Boötes. It is located 706 million light years from Earth.[1] It is classfied a double nucleus Seyfert galaxy.[2][3]

Characteristics

[edit]

Markarian 463 is a late stage galaxy merger, a product of two gas-rich spiral galaxies colliding with one another. According to optical and near-infrared observations, the galaxy is shown to have a complex morphology with star forming clumps and curved tidal tails.[4] It has a luminosity of LIR (8-1000μm) = 1011.8 LΘ making it a luminous infrared galaxy.[5] It contains a compact radio flux in either linear or elongated structure.[6] Using spectra captured by the Infrared Spectrograph installed on Spitzer Space Telescope, emission lines are detected in Markarian 463 hinting a warm supply of molecular gas.[7]

A broadband X-ray spectral analysis revealed obscured two nuclei designated as Markarian 463W and Markarian 463E, with an estimated projected separation of ~ 3.8 kiloparsec.[8] This finding makes the galaxy a dual active galactic nucleus[9] and is the third closest physical pair known after NGC 6240 and NGC 3758.[8] The two nuclei has a luminosity of L2-10keV = 1.5 x 1043 and 3.8 x 1042 erg cm−2 s−1 and 3.8 x 1042 erg cm−2 s−1.[10] Both are active and are expected to drawn close to each other over timescales of 108 years.[4]

Further investigations also notes the two nuclei. The western nucleus has a moderate radio luminosity equivalent of an extremely luminous starburst galaxy or a Seyfert galaxy through imaging detections at 6 and 20 centimeters.[11] The eastern nucleus however, is much brighter compared to the western nucleus, and is classfied a type II Seyfert galaxy. It is found offset from its peak flux and shows polarized conical wind. With a half-opening angle of ~ 15 degrees, its wind displays three mass ejection periods.[12] Using infrared spectroscopy, the eastern nucleus hosts a hidden Seyfert 1 nucleus located southwards but not co-spatial.[13]

According to Chandra X-ray data, the supermassive black hole in the nucleus of Markarian 463E has a much higher accretion rate of ~ 5x. It is also associated with emission and continuum lines. it is also shown it is older compared the nucleus of Markarian 463W, given the northern outflowing cloud and southern emission region appears generally aligned with the biconical gradient. An ALMA 12CO (2–1) observation also finds the two nuclei have molecular gas reservoirs estimated of ~ 109 MΘ and ~ 5 x 108 MΘ respectively. Given enough molecular gas provided, it is enough to feed both black holes in the galaxy.[4]

Markarian 463 has an optical jet originating from the Seyfert nucleus according to Hubble Space Telescope imaging. The jet is found to reach the end at the radio source found 1.2 arcsecs away, and is measured 0.84 arcsecs with a position angle of 182 degrees.[14]
