The gravitational potential of spiral perturbations I. The 2D (razor-thin) case
Walter Dehnen
I developed an efficient numerical method for obtaining the gravitational potential of razor-thin spiral perturbations and used it to assess the standard tight-winding approximatio…

Potential-density pairs for galaxy discs with exponential or sech vertical profile
Walter Dehnen, Shera Jafaritabar
We present axially symmetric analytical potential-density pairs with surface density similar to the Miyamoto-Nagai model, but with more realistic vertical structure. Our models clo…
