Dust lanes in galaxies, particularly in lenticular and elliptical galaxies (like Centaurus A), often show significant asymmetries, warps, and complex morphologies that are difficult to explain in standard steady-state accretion models. In a relaxed halo, gas and dust should settle into a symmetric, flat plane aligned with the principal axes of the potential. Observed asymmetries suggest either recent, unrelaxed mergers or complex, sustained non-equilibrium dynamics that challenge simple hierarchical formation scenarios where such features should transiently settle (Graham 1979; van Dokkum et al. 2015).
