A brightest cluster galaxy (BCG) is defined as the brightest galaxy in a cluster of galaxies. BCGs include the most massive galaxies in the universe . They are generally elliptical galaxies which lie close to the geometric and kinematical center of their host galaxy cluster , hence at the bottom of the cluster potential well .
In 2024, two older and more distant galaxies, JADES-GS-z14-0 and JADES-GS-z14-1, were found. [ 6 ] JADES-GS-z13-0 is located in the Great Observatories Origins Deep Survey – South (GOODS-S) field in the constellation Fornax , which includes the Hubble Ultra Deep Field .
Abell 2390 is a massive galaxy cluster located in the constellation Pegasus. [4] It is classified as an X-ray and rich galaxy clusters measured cooling rate of 200-300 M ʘ yr −1 . [ 5 ] The galaxy cluster contains a cD galaxy called Abell 2390 BCG (short for brightest cluster galaxy), associated with a complex radio source , B2151+141.
It is the brightest cluster galaxy of the galaxy cluster, WHL J143845.0+145412. [4] The galaxy acts as a gravitational lens for a much more distant spiral galaxy which is called SGAS J143845+145407. [2] [5] This creates a mirror image of the galaxy thus creating a masterpiece. [5]
2MASX J10222849+5006200 also known as PGC 2362940, is a massive Type-cD elliptical galaxy located in the constellation of Ursa Major. With the redshift of 0.15, the galaxy is located 2.4 billion light-years away from Earth. [1] An optically bright galaxy, [2] 2MASX J10222849+5006200 is the brightest cluster galaxy (BCG) inside the galaxy ...
Abell 1201 BCG (short for Abell 1201 Brightest Cluster Galaxy) is a type-cD massive elliptical galaxy residing as the brightest cluster galaxy (BCG) of the Abell 1201 galaxy cluster. [3] At a redshift of 0.169, this system is around 2.7 billion light-years from Earth, and offset about 11 kiloparsecs from the X-ray peak of the intracluster gas .
ESO 383-76 (ESO 383-G 076) is an elongated, X-ray luminous supergiant elliptical galaxy, residing as the dominant, brightest cluster galaxy (BCG) of the Abell 3571 galaxy cluster, the sixth-brightest in the sky at X-ray wavelengths. [3]
IC 4329A, also commonly referred as PGC 49051 is a Seyfert galaxy in the constellation of Centaurus. Its distance from Earth is 206 million light years . The declination of IC 4329A is approximately -30.2 degrees and was first discovered by Wilson A. S. & Penston, M. V. in 1979.
