Description
Science cases for intensity interferometry are very diverse -- ranging in interestingness from measurements that only a small community cares about to observations that (if carried out) would create a new field -- and ranging in difficulty from already operational to dreams where even feasibility hasn't been assessed yet. This presentation will show a matrix of science cases according to interestingness and difficulty. Within the matrix we can also identify four kinds of topics that present different strategic challenges. First there are the "smooth and stationary" systems, such as stellar radii or gravity darkening, which can be modelled using a few parameters. Second, there are "smooth and periodic" systems, including not only binaries but also stellar oscillations and maybe even exoplanet transits. Third, there are "irregular but stationary" targets, like giant convective cells or (maybe one day) quasars, which require image reconstruction. Fourth and last but certainly not least, are "transients". A few new simulations will be presented: one will illustrate the usefulness of Zernike polynomials as a basis set for "smooth and stationary" systems; another is a preliminary simulation of a novel signature in quasar microlensing.
