Query: Total to central luminosity ratios of quiescent galaxies in MODS as an
  indicator of size evolution   Using the very deep Subaru images of the GOODS-N region, from the MOIRCS Deep
Survey and images from the HST/ACS, we have measured the Luminosity Ratio (LR)
of the outer to the central regions of massive (M>10^{10.5}M_{Sun}) galaxies at
fixed radii in a single rest-frame for z<3.5 as a new approach to the problem
of size evolution. We didn't observe any evolution in the median LR. Had a
significant size growth occurred, the outer to central luminosity ratios would
have demonstrated a corresponding increase with a decrease in redshift.
