Abstract:

We present a new technique to decouple the nucleus/host spectra of AGNs using IFS. This technique is an extension to 3D of the 2D fitting used to decouple the nucleus/host component in AGN imaging. Unique features of IFS like (a) the super-sampling due to differential atmospheric refraction and (b) the intrinsic determination of the PSF (for type I AGNs), make this technique unique to analyze the host spectrum of AGNs using AO. We have already used it to extract the host spectrum of 3C 120 (Sanchez et la., 2004, ApJ, 615, 156).
