ZwCl 5247 BCG (Short for Zwicky Cluster 5247 Brightest Cluster Galaxy) and also known as OGC 90, is a massive elliptical galaxy located in the constellation of Virgo. The redshift of the galaxy is (z) 0.230[1] and it is the brightest cluster galaxy of a rich galaxy cluster, ZwCl 5247 which is known as ZwCl 1231.4+1007.[2][3]

Description

ZwCl 5247 BCG is an elliptical galaxy with an r-band luminosity of 12.9 magnitude based on an r-band luminosity estimation made with the Sloan Digital Sky Survey (SDSS).[4] It is also a central dominant galaxy, with its optical spectrum lacking any emission lines.[2] The effective radius is 4.4 arcseconds, with the BCG itself having a boxy morphology.[5] The total infrared luminosity of the BCG in i-band is 21.94 × 1010 Lʘ.[6]

The BCG also contains a weak radio source, with the radio core contributing a total flux density of less than 0.15 mJy and less than 0.13 at 10 GHz frequencies. The diffused aging component, interpreted as a non-core, contributes less than 3 mJy at 1 GHz.[7] The total radio power is less than 23.55 W Hz-1 at 1.4 GHz, making it a radio-quiet BCG.[8] There is no detection of hydrogen-alpha emission.[9]

The BCG has a total stellar mass of 0.40 × 1012 Mʘ. The J–K magnitude is 1.28.[10]
