Dynamics of Disk Galaxies (Invited Review)

Astrophysics and Space Science, 1986
In order to detect the gravitational effect of the dark corona component of disk galaxies, it is necessary to have surface photometry and rotation data that extend well beyond three disk-scale lengths. Such data exists now for several pure disk galaxies. There is very strong evidence for dark coronas in these galaxies.

Stability of disk-like galaxies – Part II: The Kuzmin disk

Analysis, 2007
SummaryWe prove the existence and nonlinear stability of the Kuzmin disk, a polytropic steady state of the Vlasov–Poisson system widely used in astrophysics, which has infinite support, but finite mass. As in Part I we use the variational approach by REIN and GUO.
