For late-type galaxies in the Illustris catalogue, most of their counterparts in the SAM model have the same type, and the consistency between two models is higher for lower mass galaxies. For early-type We have also inspected the lifetime (duration) of the misalignment. The decay timescale of the misalignment shows a strong anti-correlation with the kinematic morphology V/sigma and the cold gas fraction of the galaxy. The misalignment has a longer lifetime in denser regions, which is linked with the environmental impact on the host galaxy. Spiral galaxies are disk shaped galaxies with spiral structure.

Internal perturbations such as bars can drive secular evolution through gravity torques that move gas into the central regions and build up a flattened, disk-like central bulge, or which may convert an open spiral pseudoring into a more closed ring. Research from Penn’s Department of Physics and Astronomy has produced the largest catalog of galaxy morphology classification to date. Led by former postdocs Jesús Vega-Ferrero and Helena Domínguez Sánchez, who worked with professor Mariangela Bernardi, this catalog of 27 million galaxy morphologies provides key insights into the evolution of the universe. Morphology is the result of formation, evolution and interaction of galaxies with theirs enviroments.
Galaxy morphological classification is a system used by astronomers to divide galaxies into groups based on their visual appearance. There are several schemes in use by which galaxies can be classified according to their morphologies, the most famous being the Hubble sequence, devised by Edwin Hubble and later expanded by Gérard de Vaucouleurs and Allan Sandage. "Galaxy morphology is one of the key aspects of galaxy evolution. The shape and structure of galaxies has a lot of information about the way they were formed, and knowing their morphologies gives
Galaxy Morphology - a description of the structure of galaxies Clearly astronomical bodies are not uniform density spheres. Need a classification scheme to describe shapes – assume that the shapes are telling us about structure and genuine physical differences. A galaxy’s Hubble classification provides one way of describing its morphology, however, this classification scheme only considers the most prominent features: disks, bulges and bars.
They are predominantly made up of old stars. They are typically a few times more massive than the Milky Way, but there is a wide range: from
Galaxy Morphology There are lots of galaxies out there, and they come in many different flavors. Hubble proposed that galaxies be classified according to their appearance.
