ZwCl 1305.4+2941 BCG (short for ZwCl 1305.4+2941 Brightest Cluster Galaxy) is a massive elliptical galaxy which is the brightest cluster galaxy of the rich Bautz-Morgan class 1 galaxy cluster called ZwCl 1305.4+2941,[2][3] which in turn is located in the SA 57 field.[4] The galaxy has a redshift of (z) 0.24[1] and is located in the constellation of Coma Berenices.

Description

ZwCl 1305.4+2941 BCG is an elliptical galaxy with a total R-band luminosity of 12.8 calculated by Sloan Digital Sky Survey (SDSS) and a K-corrected magnitude of 16.48.[5] It is also categorized as a Type-cD galaxy dominating the center of ZwCl 1305.4+2941 cluster.[2][6] The central isophotes have a rounded appearance, with further evidence that the outer regions also display an isophotal twisting towards the small position angles.[2] The estimated absolute magnitude of the galaxy in the J band is -22.82 +0.02, while the absolute magnitude in U band is -22.42 +0.03.[7] There is an X-ray source that is coincident with its position, making the BCG an X-ray detected galaxy.[6]

The BCG is also classified as a fossil galaxy with an estimated age of 10.9 billion years. The total luminosity is 6.71 ± 0.22 × 1011 L☉ while the specific star formation rate of the BCG is 12.13 M☉ per year. The total metallicity rate is 0.028%, while the stellar mass is 1.36 × 1012 M☉.[8] Radio imaging made with the Very Large Array (VLA) found it is a radio galaxy hosting a weak radio source called 52W013 with a total radio flux density of 2.76 mJy at 1490 MHz frequencies.[9] In 1988, it was classified as a red radio galaxy, with the source having a small appearance with a straight radio spectrum over the spectral bands.[10]
