Hello Dana,
This piece is now quite old (I think it has been sitting on my computer for over half a decade), however it is remarkable that little work has been done on the Centaurus Cluster of Galaxies since it was written.
From time to time, I have spent happy days exploring the clustering of galaxies and finding redshift similarities between various galaxies. You can learn a lot about galaxy clustering simply by bringing up a lot of galaxy redshifts and then finding groupings of galaxy redshifts. For instance, I have found several examples of well-defined clusters of galaxies that have smaller galaxy groups falling into them, simply from looking at the redshift patterns.
One of the subclusters of the Centaurus cluster has a peculiar (individual)(noncosmological) velocity of 1500 km/s in the line-of-sight.....this fact could have been found by an amateur astronomer just looking at the redshifts of the galaxies!!
I really should include some diagrams and photos so as to make my points about the Cen. Cluster more obvious.
Best regards,
Robert
