WISEA J160318.98+031644.8 also known as OGC 1012, is a radio galaxy located in the constellation of Serpens. The redshift of the galaxy is (z) 0.222[1] and it was first discovered in a sample of 2,712 radio-loud active galactic nuclei obtained by the Sloan Digital Sky Survey (SDSS) in September 2005.[2]

Description

WISEA J160318.98+031644.8 is a giant elliptical galaxy of type E morphology.[3] It is also a luminous red galaxy found to reside in the center as the brightest cluster galaxy (BCG) of the galaxy cluster, WHL J160319.0+031645 with at least 114 confirmed member candidates.[4][5] The estimated J-band and H-band infrared color magnitudes of the galaxy is 15.84 and 15.00 magnitudes respectively.[6] The absolute magnitude of the galaxy is -23.42 and it has a total stellar mass of 11.34 Mʘ.[7][8]

The nucleus is active and has been categorized as a Fanaroff-Riley Class Type II radio galaxy. The radio flux density calculated by the NRAO VLA Sky Survey (NVSS) at 1.4 GHz frequencies is 127.00 mJy.[7] The radio luminosity is 25.26 W Hz-1.[8]

A study published in 2022, found it is a bent-tailed radio galaxy which can be further classified as a wide-angle tail radio galaxy. The total flux density estimated at 1.4 GHz is 132.94 mJy, while the flux density at 3 GHz is 66.86 mJy. The spectral index between 1.4 and 3 GHz is 0.9α. A radio jet has been detected, with a jet opening angle of 132.8° and a jet curvature radius of 30.8 arcseconds.[9] The radio lobes are resolved, with a flux density of 0.128 Jy and have lobe to lobe separation by 0.002° while the radio core remains undetected.[10] The largest angular size of the galaxy is 34 arcseconds and the largest linear size is 126.0 kiloparsecs.[9]

Evidence also found the source is a double, with an approximate bending angle of 41.3°. The excess bending angle is 34.4°.[11]
