Galaxy effective radius: Standards & Overview

Galaxy effective radius or half-light radius ( R e {\displaystyle R_{e}} ) is the radius at which half of the total light of a galaxy is emitted. This assumes the galaxy has either intrinsic spherical symmetry or is at least circularly symmetric as viewed in the plane of the sky. Alternatively, a half-light contour, or isophote, may be used for…
