Distributions of the Sérsic index (n) from GALFIT fits for AGNs and inactive control galaxies in two HST bands: the ACS/F850LP band (bottom panels) and the WFC3/F160W band (top panels). Panels left to right span three distinct bins in redshift. Only the subset of sources contained in the FIREWORKS catalog are here. 1000 draws of a mass-matched control sample are analyzed to determine the 1σ/2σ scatter in the n distributions for inactive galaxies, shown as dark/light grey zones in the histograms. Red open histograms show the parameter distributions for the AGNs. Sérsic indices are typically lower in the bluer F850LP band. Especially at 1.5 <z< 2.5, the n histograms of the AGNs are more consistent with those of the inactive galaxies from the F850LP fits.
