Strong size evolution of disc galaxies since z = 1. Readdressing galaxy growth using a physically motivated size indicator
Our understanding of how the size of galaxies has evolved over cosmic time is based on the use of the half-light (effective) radius as a size indicator. Although the half-light radius has many advantages for structurally parameterising galaxies, it does not provide a measure of the global extent of the objects, but only an indication of the size of
