So all this time I have been looking at a galaxy, albeit a small one, and never realised! This means Omega Centaurii is the first galaxy I saw with my telescope, not Andromeda as I previously thought.
The article is very thought provoking, but I guess the bit about different ages of stars and the presence of a black hole indicate the core of a galaxy rather than a globular cluster.
Could the black hole also contribute significantly to the tight grouping of stars in Omega Centaurii?
