Description

edit

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]
