To find the spectral properties of AGNs in optical spectral band (around the Hb line) we constructed an Fe II template, that is covering Fe II emission from 4100 A to 5600 A. Using the new Fe II template we explored spectral properties of…

This is the first paper of a series exploring the multi-frequency properties of a sample of eleven nearby low excitation radio galaxies (LERGs) in the southern sky. We are conducting an extensive study of different galaxy components (stars,…

The model I recently proposed for the structure of quasars (astro-ph/0008064) claims to unify all the emission, absorption and reflection phenomenology of quasars and AGN, and so is heavily overconstrained and readily tested. Here I…
