José Luis Sérsic was an Argentine astrophysicist and astronomer known for his significant contributions to the study of galaxies. He is best known for developing the Sérsic law, which describes how the surface brightness of elliptical galaxies and bulges of spiral galaxies varies with distance from their centers. The Sérsic law generalizes the de Vaucouleurs profile and provides a more accurate representation of the light profiles of various types of galaxies.
