Have there even been two non-spiral galaxies collided with each other?

Probably the type of galaxy has nothing to do with the odds of colliding galaxies

 

One of the largest galaxy mergers ever observed consisted of four elliptical galaxies in the cluster CL0958+4702. It may form one of the largest galaxies in the Universe.

Lots more interesting information there.

Four elliptical galaxies at once! I didn't even know more than two galaxies can be involved. Does this only happen to eliptical galaxies, or can f.i. 3 spiral galaxies also merge at the same time? Or how about 2 spiral galaxies, and 1 elliptical one??

Any number and any type of galaxies can 'collide'. It simply depends on their relative vectors. If they end up in the same space at the same time, they're colliding. And that's all dependent on gravitational attraction.

We have studied in great depth the "collision" of two clusters of galaxies

I think we have to understand the question about this way: does it was registered observable collision of two non spiral galaxies?

Ha! Beaten to it.

see? you can do it more simple way

Thanks everybody! That really helped me!
