We have analyzed the deep Chandra observation (~155 ks) of the Compton ThickActive Galactic Nucleus (CT AGN) ESO 428-G014, to study in detail themorphology of the diffuse X-ray emission in the inner ~500 pc radius region.Comparing different X-ray energy bands we find localized differences in theabsorbing column and in the emission processes. Collisional ionization may beprevalent in the area of most intense optical line emission (Halpha and[OIII]). There is a good correspondence between optical line, radio continuumand soft (<3 keV) X-ray features, consistent with simulations of jet/moleculardisk interactions. At all energies >3 keV, the extended emission in the central1".5 (170 pc) radius circumnuclear region amounts to ~70-30% of thecontribution of a point source in that area (or 40-25% of the total counts inthe region). Within a 5" radius, the contribution from extended emissionovercomes that from a nuclear point source in the 3-4 keV band. This extendedemission suggests scattering of nuclear photons by dense molecular clouds inthe inner galactic disk of ESO 428-G014. Its presence may adversely bias thetorus modeling of spectra from X-ray telescopes with inferior angularresolution than Chandra, such as NuSTAR and XMM-Newton.
