3C75
Encyclopedia
3C75 is a binary
black hole
system in the Abell 400
cluster of galaxies. It has four radio jets (two from each accreting black hole). It is travelling at 1200 kilometers per second through the cluster plasma, causing the jets to be swept back. The binary supermassive black holes are themselves contained in the dumbbell shaped galaxy NGC 1128
. 3C 75 may be X-ray source 2A 0252+060 (1H 0253+058, XRS 02522+060).
Binary star
A binary star is a star system consisting of two stars orbiting around their common center of mass. The brighter star is called the primary and the other is its companion star, comes, or secondary...
black hole
Black hole
A black hole is a region of spacetime from which nothing, not even light, can escape. The theory of general relativity predicts that a sufficiently compact mass will deform spacetime to form a black hole. Around a black hole there is a mathematically defined surface called an event horizon that...

Abell 400
Abell 400 is a galaxy cluster, containing a galaxy with two supermassive black holes 3C 75 spiralling towards merger.These two supermassive black holes are contained in NGC 1128. The galaxy, microwave radio jets, multi-million degree X-ray producing gas and resultant radio source is known as 3C 75...

NGC 1128
NGC 1128 is a "dumbbell galaxy" in the Abell 400 galaxy cluster. It is the center of the 3C75 radio source and contains two orbiting supermassive black holes that may be merging. Computer simulations indicate that these two black holes will gradually spiral in toward each other until they merge....
