Fig. 4
Illustration of the AGN simulation procedure. Upper left: original quiescent galaxy at redshift z = 0.52, apparent brightness v = 23.27. Upper middle: star of brightness v = 21.46 used as a synthetic nucleus. Upper right: simulated AGN (co-added galaxy and star) with a host-to-nucleus ratio of H/N = 0.18. Lower left: GALFIT model of the host galaxy (from fitting a nucleus + host model to the simulated AGN). Lower middle: recovered host galaxy after subtracting the GALFIT model of the nucleus from the simulated AGN image. Lower right: residual after subtracting the combined galaxy + nucleus model from the simulated AGN image. Each image is ~ 2 arcsec on the side.
