SDSS J121143.17+080108.3 also known as OGC 92, is a radio galaxy located in the constellation of Virgo. The redshift of the galaxy is (z) 0.248[1] and it was first discovered as a discrete astronomical radio source from the 87GB Catalogue of Radio Sources by astronomers in April 1991.[2]

Description

SDSS J121143.17+080108.3 is a supergiant elliptical galaxy with a Type E galaxy morphology.[3] It is also a red luminous galaxy residing as the brightest cluster galaxy (BCG) in the center of the galaxy cluster, WHL J121143.2+080108, with 47 confirmed galaxy member candidates.[4][5]

The total r-band magnitude of the galaxy is 16.44 magnitude and the total infrared i-band luminosity is estimated to be 24.32 × 1010 L☉.[5][6] The absolute magnitude of the galaxy is -24.16.[7] A total stellar mass of 11.51 h−2 M☉ has been calculated for the galaxy.[8]

Its nucleus is active and it has been categorized as an ordinary Fanaroff-Riley Class Type I radio galaxy with its total radio flux density estimated as 85.00 mJy at 1.4 GHz frequencies by NRAO VLA Sky Survey (NVSS).[9][10] The radio power at 1.4 GHz is 15.82 × 1024 WHz−1.[7] The size of the source is approximately 33.63 arcseconds.[10] A study published in 2018 has calculated the 1.4 GHz flux density is 87.1 mJy and the radio luminosity is 25.19 WH z−1.[8]
