The galaxy model

How space flows through a galaxy, and how a constant-Lagrangian inflow shapes spiral arms, nested spirals and the Hubble sequence.

    Fitting real rotation curves

    Step-by-step fits to SPARC data: one Lagrangian, two Lagrangians, and a constant offset.

      Jets

      Painlevé–Gullstrand cone flows: polar jets in 3D and the jet of M 87.
