Emission Line Region in a sample of 12 active galactic nuclei

We present a study of the emission line profiles of a sample of 12 single-peaked Active Galactic Nuclei (AGNs- Sy 1 and QSOs). The narrow [OIII] lines seem to be related to two components; NLR1, which has dispersion velocities from 200 to 500 km s-1 and is blueshifted with respect to the systemic by about 20 to 350 km s-1; and NLR2, with smaller dispersion velocities (∼100-200 km s-1) and a redshift corresponding to the cosmological one. The broad lines have complex structure and a two-component model has been applied.
