Galaxy Morphology: Foundations

Galaxy morphology describes the visible and structural forms of galaxies, including spirals, barred spirals, ellipticals, lenticulars, irregulars, and peculiar systems. Morphology gives a first-order description of galaxy structure and helps organize studies of galaxy evolution, star formation, mergers, and environmental transformation.

Galaxy morphology describes the visible and structural forms of galaxies, including spirals, barred spirals, ellipticals, lenticulars, irregulars, and peculiar systems.

supported

Galaxy form reflects angular momentum, gas supply, mergers, tidal interactions, bars, star formation, and environmental processes.

supported

Imaging across optical and infrared wavelengths reveals stellar structure, while gas maps and spectra connect shape to kinematics and star formation.
