The LSST can see quasars at very large red shift. I recall that this was raised as a possible LSST science topic a year or so ago. Is it being actively pusued by the SWG? I can think of two topics: * Quasar distribution as a measure of large scale structure. * The dynamics of quasar formation. There was a recent Nature article on this topic.
