WebThe morphological classification of galaxies divides them into elliptical, spiral, barred spiral, and irregular, along with various subclasses ( Hubble, 1926 ). This classification system is called the Hubble sequence and was invented by Hubble (1926). Galaxy morphology is a complex phenomenon that correlates to the underlying physics.
WebMay 10, 2010 · Description of the system. In an attempt to accommodate the entire range of morphological characteristics of galaxies de Vaucouleurs (1959a) introduced a three-dimensional classification scheme which is illustrated in Figure 5. The main axis of this classification system is the sequence E–S0–Sa–Sb–Sc–Sd–Sm–Im, where the index m ... WebThe field of galaxy evolution faces a particularly challenging future as complete understanding often cannot be reached without analysis of detailed morphological galaxy features. Historically, morphological analysis has relied on visual classification by astronomers, accessing the human brains capacity for advanced pattern recognition.
The Hubble sequence is a morphological classification scheme for galaxies invented by Edwin Hubble in 1926. It is often known colloquially as the “Hubble tuning-fork” because of the shape in which it is traditionally represented.
