Quirrenbach Topic: 5 Session: oral Abstract: Future large optical/infrared interferometers with large telescopes and baselines of several km length can provide sub-milliarcsecond resolution, high sensitivity, and good sky coverage. They can perform imaging spectroscopy of AGN broad line regions, and measure geometric distances to these objects. I will discuss the science case and technical issues for such a next-generation interferometric array.
