A2261-BCG (short for Abell 2261 Brightest Cluster Galaxy) is a huge elliptical galaxy in the cluster Abell 2261. One of the largest galaxies known, A2261-BCG is estimated to have a diameter of a million light-years, some 10 times larger than the Milky Way. It is the brightest and the most massive galaxy in the cluster, and has one of the ...
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. [6] [7]

The elliptical galaxy LEDA 1900245, is the brightest cluster galaxy (BCG) of RX J1532.9+3021. It has a dimension of around 120.56 kpc (~393,000 light-years) and is a LINER galaxy, meaning a galaxy whose nucleus contains an emission spectrum characterized by broad lines of weak ion atoms. [8]
3C 454.3 is a blazar (a type of quasar with a jet oriented toward Earth) located away from the galactic plane.It is one of the brightest gamma ray sources in the sky, [2] and is one of the most luminous astronomical object ever observed, with a maximum absolute magnitude of -31.4. [3]
ESO 383-76 is a supergiant elliptical galaxy (type-cD galaxy) of an advanced Hubble morphology (E5, with E0 being spherical and E7 being flattened), with its major axis being more than twice the length of its minor axis. The galaxy is a very luminous source of X-rays, and is the sixth-brightest X-ray source in the sky. [3]
In “The Thing with Feathers,” Benedict Cumberbatch plays a London creator of graphic novels who, quite suddenly, finds himself a widower (his beloved wife collapsed on the kitchen floor and died).
The galaxy known as NGC 3842 is the brightest member of this cluster. [4] Along with the Coma Cluster , it is one of the two major clusters comprising the Coma Supercluster , [ 5 ] which in turn is part of the CfA2 Great Wall , which is hundreds of millions light years long and is one of the largest known structures in the universe.
