A New Exploration of "Fell Problem" in Active Galactic Nuclei I——Preliminary Consideration

Since the unknown emission features in the spectrum of quasar 3C 273 have beenfirst identified as the blended Fell multiplets, many papers have contributed to thetheoretical and observation research of Fell emission in the spectra of Seyferts andquasars. Usually, optical FeII emission lines are prod...
