Data on the Velocity of the Celestial Bodies Orbiting a Galaxy

  1. Jul 14, 2014 #1
    I am currently researching about the behavior of dark matter and their possible characteristics, and I am needing the individual velocities of the bodies orbiting a center of a galaxy. The collection of data where physicists hypothesized the existence of Dark Matter. Where can I find these data? If ever possible.

    Thank you in advance.

    In scientific publications. The references in this wikipedia article should be a good starting point.

    Be sure to click on that link in the wiki for Vera Rubin. She seems an amazing researcher and receives far too little credit for the storm she caused.
