what is it?
You can see that galaxy attracts other galaxy.
I think that galaxy cant attracts other galaxy, because it is galaxy must have great mass. Therefore i think that is black hole attracts this galaxy.
In support of this spectra on which we can say many lights and heavy elements. Absorbing gas and star black hole give many heavy and light elements.
If i dont true, say me what is it?

Hi, can you provide the ID of the galaxy? It would make it easier.
Black holes make up less than 1% of the mass of a galaxy, so you should look at the size of the galaxy. You are generally correct about the elements that you see in the spectrum.
