Formation of disk galaxies with long-lived and non-stationary spiral arms

This work represents a development of the study of the collapses of purely self-gravitating systems  (see https://physics.aps.org/articles/v12/s19) to the case in which a dissipational gas component is also present. These latter systems show much richer morphological and kinematical structures that may have important observational implications to understand the kinematic and dynamics of the Milky Way as revealed by ongoing surveys such as the Gaia Mission.
