SDSS J1239+5314 also known as SDSS J123915.40+531414.6, is a Type 1 Seyfert galaxy located in the constellation of Ursa Major. The redshift of the galaxy is (z) 0.201[1] and it was first discovered by astronomers in June 2010, whom they classified a double-peaked profile active galactic nucleus (AGN).[2]
Description
SDSS J1239+5314 is categorized as a Type 1 AGN.[2][3] It is also a galaxy merger with the two nuclei estimated to be have a physical separation of 4.1 kiloparsecs away from each other. The total K-band magnitudes of the components are 14.4 and 14.8 respectively. The total rest frame radio luminosity at 5 GHz frequencies is estimated to be 24.1 W Hz−1.[4] Observations made in March 2011, showed it has a Fanaroff-Riley Type II morphology with a faint radio core. The total integrated flux density of the source is found to be 23.11 mJy.[5] The star formation is estimated to be 6.013.64.2 M☉ per year while the total stellar mass is 11.810.530.59 M☉.[6]
A study published in 2015 has found there are two emission components present with the separation approximately around 1.3 kiloparsecs. When observed, the blueshifted component has a stellar bulge that is coincident with it, while the redshifted component does not. There is also another emission component present with a larger distance of 3.98 kiloparsecs and coincident with the stellar bulge of the southwest nucleus.[7]
In 2022, the galaxy was found to be a confirmed X-shaped winged radio galaxy with the radio lobes being aligned from northeast to southwest direction. The position angle between the lobes is estimated to be 79°. Evidence also found the wing feature on southeast side is much longer compared to the northwestern wing.[8]
