The multiple faces of today’s galaxies: their morphologies tell their evolutionThe large morphological classes of galaxies have fascinated astronomers since their discovery. A new analysis led by Louis Quilley, PhD student (Sorbonne University), and Valérie de Lapparent, researcher at the Institut d'Astrophysique de Paris (IAP), establishes a physical link between the order of the different types of the famous Hubble sequence, and the systematic evolution of galaxies.
