High School Orbits of galaxies in the Coma Cluster

[Buckethead]

Because of Zwicky'f findings back in 1933 on the Coma Cluster rotational curves there is something I was wondering about with regard to this cluster. Are the galaxies orbiting in generally the same direction? (like a spiral galaxy) or in completely random directions like an Elliptical, or something in between the two (a spiral where some galaxies orbit at an angle above or below the disk plane?). Has anyone done an animation of the movements of the galaxies in the Coma or similar cluster? I read of a computer simulation of mass points similar to the Coma and I guess the interactions were quite complex because of the lack of a very strong central gravity but could not find out much more. Galaxy clusters similar to the Coma are fine too. Just curious about the general dynamics of any "typical" cluster (if there is such a thing). Thanks.

You are confusing the findings of Zwicky with those of Vera Rubin. Zwicky's conclusions were based on the virial theorem.

Ah, perhaps. I thought Zwicky was using redshift to observe speeds of galaxies in the Coma Custer and found them to be too fast. Similar to Rubin, but on a cluster scale instead of a galactic scale. What I couldn't find out was the actual trajectories of the galaxies in the Coma which is what I'm particularly interested in.
