Paper Abstract

Using adaptive optics on the Keck Telescope and the VLT, we are able to probe the dynamics and star formation in Seyfert and QSO nuclei on spatial scales better than 0.1" in the H- and K-bands. Such spectroscopic data are essential for studying the link between AGN and star formation, understanding how gas is driven into the nucleus, and measuring the black hole mass. In this contribution we present some of our recent results, and consider what an astronomer needs from an adaptive optics system for extragalactic work, as well as what is realistic to expect. We discuss why deconvolution is not appropriate in this context; and examine the scientifically more useful alternative of convolving a model with an estimate of the PSF, describing what level of detail and reliability can actually be achieved in the various methods of measuring the PSF.
