Abell 1650 BCG (Short for Abell 1650 Brightest Cluster Galaxy) is a massive elliptical galaxy of type-cD located in the constellation of Virgo. It has a redshift of (z) 0.084 and is the brightest cluster galaxy (BCG) of the Bautz-Morgan Type I-II galaxy cluster, Abell 1650, with an extrapolated magnitude of 10.31 ± 0.41 × 1011 .
Description Abell 1650 BCG is classified as a type-cD galaxy dominating the center of Abell 1650. The BCG is radio-quiet based on radio imaging by the Very Large Array (VLA) with no sign of radio emission associated with it. A faint radio source has been detected through deep imaging at 1.4 GHz frequencies coinciding with the BCG's position with a total flux density of 0.44 ± 0.09 mJy and a radio power of 7.6 × 1021 W/Hz. The optical center of the BCG is misaligned by 23 kiloparsecs towards the southeast direction along with the X-ray surface brightness peak. There is also evidence of X-ray emission around the BCG.
The U–R color magnitude of the BCG is estimated to be -0.05 ± 0.11, while the U–I color magnitude is -0.02 ± 0.11. A study published in November 2020, found the BCG has an intermediate stellar population with the inner population aged 6,640 ± 970 million years, while the outer population is aged 5,550 ± 370 million years. The core of the BCG has a red appearance. The total stellar mass of the BCG is estimated to be 7.2 ± 1.4 × 1011 . A supermassive black hole is at the center of the BCG ,with a mass of 7.58 × 109 .
The BCG also displays kinematic properties. It has a central velocity dispersion of 412 ± 18 kilometers per second, while the rotation is measured to be 0.10 ± 0.07 Vmax.
