Redshift evolution of the size-luminosity relation from z ~ 0 to z = 7. The cyan empty stars show the local relation found by de Jong & Lacey (2000), taking the absolute magnitudes in the I band from their work and applying a constant shift M_UV − M_I = 1.0. The blue line is the relation by Roche et al. (1996) for irregular galaxies at z ~ 0.5, the empty squares and triangles represent galaxies at 0.7 < z < 1.4 and 1.9 < z < 3.0 by Papovich et al. (2005) and the pentagons are the typical half light radii of LBGs at z = 2.5 (magenta, top), 3.8 (green), 4.9 (brown), and 6.0 (grey, bottom) by Bouwens et al. (2004). The black dots with error bars are the z = 7 relation found in this work.
