SDSS J132020.35+485409.1 also known as 6C B131811.2+490938 and RGZ J132020.2+485409, is a radio galaxy located in the constellation of Canes Venatici. The redshift of the galaxy is estimated to be (z) 0.232.[1]

Description

SDSS J132020.35+485409.1 is classified as a luminous red galaxy residing as the brightest cluster galaxy (BCG) of the galaxy cluster, WHL J132020.4+485409.[2][3] The r-band magnitude of the galaxy is 17.24 magnitude while the absolute magnitude is -23.07.[2][4] A supermassive black hole is located in the center of the galaxy with a mass of 8.42 M☉.[5]

The optical spectrum of the galaxy displays emission lines of mainly hydrogen-alpha and doubly ionized oxygen with the line luminosities estimated as 6.612 and 6.160 L☉.[5]

The nucleus is also active and has been classified as a Fanaroff-Riley Class Type I radio galaxy. It ihas radio lobes with a total size of 78.53 kiloparsecs. The total radio luminosity is 25.53 W Hz−1.[5] A study in 2011, had previously categorized it as a Fanaroff-Riley Class Type II radio galaxy with a total radio flux density of 69.4 mJy. The angular size of the source is 20 arcseconds while the linear size is 74.07 kiloparsecs. There no evidence of either a radio core or hot spot features.[6]

A study published in 2019, found it is a bent-tailed radio galaxy with the flux density of 65.60 mJy, obtained from the NRAO VLA Sky Survey (NVSS).[4] The source is also bent, with its approximate bending angle measured to be 33.2. The excess bending angle is 30.4°.[7]
