Dec 15, 2016 at 19:07 comment added ProfRob What is ambiguous is what it is meant to represent and how you have calculated it. Also, the plot has no labels on it at all, which is why I assume it is something you have calculated. It is not in the paper you reference. @MikeDoonsebury
Dec 15, 2016 at 18:27 comment added user32023 The plot is clearly labelled "Mass" and the units are $10^9$ solar masses. Please explain what part of this is ambiguous and I'll try to correct it.
Dec 15, 2016 at 17:29 comment added ProfRob @MikeDoonsebury The core is more dense - as I explain quite clearly above. It behaves roughly as $\rho \propto r^{-1}$. Your graphs are not density versus radius. This is why I have asked you (twice) to explain exactly what you are plotting.
Dec 15, 2016 at 17:10 comment added user32023 Thanks for the information, but I'm not sure I communicated my question properly. Why is it $shapped$ like this. All other objects bound by gravity, well, gravitate and Dark Matter has only one job: gravitate. Take away the baryonic mass and you have the same question: why isn't the core more dense than the outer region (except to create a flat velocity curve which would be an ad-hoc justification for it's shape)?
