WISEA J142040.84+065059.8 also known as J142040.86+065059.5, is a radio galaxy located in the constellation of Virgo. The redshift of the object is (z) 0.237[1] and it was first discovered as a discrete radio source from the Molonglo Reference Catalogue by astronomers in February 1981, where it was designated as MRC 1418+070.[2] It is categorized as a blazar and also a quasar.[3][4]

Description

WISEA J142040.84+065059.8 is a red luminous galaxy[5] residing as the brightest cluster galaxy (BCG) of the galaxy cluster, WHL J142040.9+065059 with 13 confirmed galaxy member candidates. The r-band magnitude of the galaxy has been estimated as 17.45 magnitude.[6] Its absolute magnitude has been estimated as -22.89.[7] A supermassive black hole is present in the center of the galaxy with a mass of 8.64 Mʘ.[8]

The nucleus is active and has been classified as a bent-tailed radio galaxy of Fanaroff-Riley Class Type I subtype or an X-shaped radio galaxy. The total radio flux density has been calculated as 463.00 mJy by the NRAO VLA Sky Survey (NVSS) at 1.4 GHz frequencies.[7] There is a radio jet with the jet opening angle estimated as 163.6° and the jet curvature radius is 52.5 arcseconds. The radio logarithmic luminosity is 26.07 W Hz-1. The largest angular size of the source is 75 arcseconds whereas the largest linear size is 292.0 kiloparsecs.[8] The total radio power is 90.34 × 1024 WHz-1.[9]

It is a weak blazar with a compact steep spectrum (CSS) source. The total flux density is 21.6 mJy and it has a core-jet structure with the core flux density being estimated to be 11.8 mJy. The major axis position angle of the source is 151°.[3] It is also a steep spectrum radio quasar, mainly characterized by its steep radio spectrum.[10]

A study published in 2015, has found it is an S-shaped radio galaxy with a source extent of 0.19 kiloparsecs.[11] There is a possibility it might be a dual active galactic nucleus (AGN) candidate with both redshifted and blueshifted doubly ionized oxygen emission lines having a velocity offset of 253 kilometers per seconds.[12]
