The data for this table were derived from our review of astronomy/astrophysical journals and various online sites, including nasa.gov, Wikipedia.org and others.   There is great paucity of data for the parameters we were particularly interested in (axial rotation speeds and radial velocity, vs mass/size of the galaxies).  We tried to select large galaxies and compare them with medium-sized ones such as our Milky Way Galaxy.  Apparently, the largest of the galaxies are also the farthest and clearly the availability of data is severely hampered by that fact alone.  Thus, on this table we are left with comparison of only a few galaxies (Nos.1,6,7,8 vs 10 & 11).  Even with this sparse data, there is a good hint that the galacto-radial and helio-radial velocities are higher, the larger the galaxy is.  Taken together with the recent observation (5) of the “Super Spirals” rotating even faster, we can safely predict that future availability of accurate information will confirm our belief.
