Abstract: (EDP Sciences)
Context. Many classes of active galactic nuclei (AGN) have been definedentirely through optical wavelengths, while the X-ray spectra have been very useful toinvestigate their inner regions. However, optical and X-ray results show manydiscrepancies that have not been fully understood yet.
Note:
  • galaxies: active
  • galaxies: Seyfert
  • X-rays: galaxies
