The most obvious extragalactic targets for optical/infrared interferometers are Active Galactic Nuclei. In this document, I try to overview other topics that could be of interest to studies of galaxies and whether they could be adequate for a next generation interferometer. The very high spatial resolution would be profitable for extragalactic supernovae, globular clusters, star forming regions, gravitational lenses and some stellar studies in very close galaxies. However, sensitivity is the main concern since the interesting magnitude limit would have to be of the order of 25 or more for these studies not to remain marginal.
Towards a Small Prototype Planet Finding Interferometer: The next step in planet finding and characterization in the infrared
在过去的几年中,相当大的努力已经指向大规模(>> $1 Billion US) missions to detect and characterize earth-like planets around nearby stars, such as the Terrestrial Planet Finder Interferometer (TPF-I) and Darwin missions. However, technological and budgetary issues as well as shifting science priorities will likely prevent these missions from entering Phase A until the next decade. The secondary eclipse technique using the Spitzer Space Telescope has been used to directly measure the temperature and emission spectrum of extrasolar planets. However, only a small fraction of known extrasolar planets are in transiting o…
