Dual-core galaxy?

Question

I'm just asking if this concept seems even feasibly possible. The way I'm thinking, the cores(which are of course likely super massive black holes) would rotate around each other, and the stars of the galaxy around that. It probably wouldn't be a barred galaxy.

But my expertise stops at my college stars and stellar course, so I figured I'd ask someone who might know more.

Would it be physically possible for a galaxy with two centers or cores to not only exist, but do so in a stable manner?

Answer 1

Yes I think it is possible, although it's probably only a transitory phase when galaxies merge with one another. The cores will orbit each other but will eventually merge, the larger one effectively consuming the smaller one.

It's believed that Andromeda may have a dual-black hole nucleus.

Answer 2

the galaxy is not a processor

the sun is the center if the universe

another sun does not exist where that sun exists

Answer 3

Physically possible?  Certainly.

It could occur if two galaxies with very specific velocities were to merge.  It could also occur in a single galaxy if it was rotating with sufficient speed.

Both scenarios are highly unlikely.  But, I wouldn't be surprised if it happens once in a while.

Answer 4

Nothing would be stable.

You've pretty much described what happens when two galaxies collide, but eventually, the black holes would become one.

Can you imagine what youve just said? It'd be two spirals going around each other. Billions of stars would be smashing into each other. So cool. I'd like some photos from ESA or NASA if these exist though.

I too only have a cosmology course from uni, but I'd like to think my knowledge can cover that.
