Image Details
Caption: Figure 6.
Right: host galaxy morphological distortion, parameterized as D, the ratio of the Gini coefficient ( G) to the concentration index ( C) against Eddington ratio. Normal galaxies have a mean D ≈ 1.2 (Abraham et al. 2003), objects with values below this (shaded in the plot) are relatively undisturbed, those with higher values have increasing amounts of disturbance. Symbol colors as for Figure 4. Left: morphological distortion vs. the log of the ratio of far-infrared luminosity to host luminosity in B band, an indicator for star formation. While there could be a hint of a correlation between the amount of host disturbance and the accretion rate, there is no correlation found for star formation vs. the host disturbance.
