Consequences of the interaction between baryonic matter and dark energy carrier is considered for spinning objects. Some morphological features of spiral galaxies are used as fingerprints of formation processes to show that spiral arms of galaxies could be formed through mass ejection from the core of these objects. The Elmegreens’ arm classification allows one to find some opportune features for this end. For the same purpose, the ratio of vertical and radial sizes of some edge-on spiral galaxies found in deep fields and SDSS surveys is used.
