Web20 R.Cowsik & P. Ghosh v =Vr/(2kTv/mv) 1/2 and ξ Flat and gently rising rotation curves arise naturally in this model. This can be seen qualitatively by noting that when the background gas is absent the visible matter has an Emden distribution, i.e. ρv ∼ r-–2,∂Ψv/∂r ∼ r-–1 and r(∂ψv/∂r) constant; i.e. an exactly flat rotation curve results.
