Abstract

We will present recent results from a series of HI absorption observations of 3C 293 made using the GMRT, VLA + Pie Town, MERLIN, global VLBI and combinations of these data sets. Broad HI absorption is detected against the entire sub-arcsecond radio continuum source in all of these experiments. These observations have enabled us to trace the dynamics a distribution of HI on scales down to just a few pcs. We have detected large velocity gradients within the HI gas associated with the AGN which are interpreted as a ring of neutral gas located at a radius of only a few hundred parsecs from the nucleus.
