galaxy morphological classification

Galaxy morphological classification is a system used by astronomers to divide galaxies into groups based on their visual appearance.

It is designated with an SA in the galaxy morphological classification scheme.

There are three main galaxy morphological classifications: Ellipticals, Spirals and Lenticulars.

It has a galaxy morphological classification of SA(s)m and is highly irregular, with only the barest indication of any spiral arm structure.

Abraham's career has been notable for his contributions via non-parametric statistics to galaxy morphological classification, especially at high-redshift and early work on the Hubble Deep Field.

A lenticular galaxy is a type of galaxy which is intermediate between an elliptical galaxy and a spiral galaxy in galaxy morphological classification schemes.

The Small Magellanic Cloud remains classified as an Irregular galaxy of type Im under current Galaxy morphological classification, although it does contain a bar structure.

In the modified Hubble sequence galaxy morphological classification scheme of French astronomer Gérard de Vaucouleurs, Messier 87 is categorized as an E0p galaxy.

Although its overall structure is quite complex, the galaxy does have a very faint spiral arm structure which has resulted in it receiving a galaxy morphological classification of SAB(s)d.

It forms a pair with its neighbouring galaxy Sextans A. It is a type Ir IV-V galaxy according to the galaxy morphological classification scheme.

He also developed several galaxy morphological classification systems, including the first systems to use the physical, quantifiable properties of galaxies, as opposed to simple, qualitative, eye-ball estimates favoured by Edwin Hubble.

In the French astronomer Gérard de Vaucouleurs' revised Hubble Sandage (VRHS) system of galaxy morphological classification, the Triangulum galaxy is classified as type SA(s)cd.
