Abstract

The nuclei of active galaxies harbor massive young stars, an accreting central black hole, or both. Results are presented for molecular gas that is exposed to X-rays (1-100 keV, XDRs) and far-ultraviolet radiation (6-13.6 eV, PDRs). Particular attention is paid to species like HCN, HNC and HCO(+). Line ratios of HCN/HCO(+) and HNC/HCN discrimination between PDRs and XDRs.
