Study of quasar broad emission region from spectroscopy of multiple images

Abstract

Using the high resolution radio observations and analysis of the broad emission lines as well as continum in the optical spectra of the multiple images of quasars, we provide a method to probe the structure and dynamics of the broad emission region of AGNs. From the study of the system 1422+231 we establish that the optical and radio emission of the source originate from two different regions.
