Another question: - Is it likely that the presence of the two smaller "massive star clusters" (massive stars, or massive clusters?) suggests the presence of a galaxy forming influence in the area that tails off a bit in their direction?

Off the metallic subject I know, but..... I am astounded to hear that dwarf galaxies are the most common of galaxies. I had perhaps by popular images of spiral ones been led to believe they were the "standard" galactic formation. Now I wonder that since another factoid I remember, that we ...

Humbly I suggest I already considered that:- "but with some remaining attraction to the galactic C of G?", I have Googled "barycentre" & think we are talking about the same thing?. As for Hawking radiation, that is not on the time-scale we are discussing. I am being run-it-up...

Does anyone know if a simulation has been run of the evolution of a galaxy with a black hole at the centre if the black hole suddenly disappeared? Presumably all matter orbiting it's C of G would move off at a tangent, but with some remaining attraction to the galactic C of G? Would it produce a bar...

The shadows of the legs look as though its steeper and further down to the right, my bet is different levels, tops of smaller-scale frost heaves?
