COAST: the Cambridge Optical Aperture Synthesis Telescope

At MRAO, a considerable amount of my time is spent working as part of the COAST team on our optical and near-infrared interferometer. Details of the instrument, and up-to-date news on our science programme can be found on the COAST page.

Also there is a database of all papers from the COAST team, as well as links to other interferometry sites. Particularly useful is the page prepared by Peter Lawson from which you can get to most optical interferometric sites worldwide.

As well as working on COAST, I have a number of ongoing collaborations with astronomers in Berkeley, Sydney, and Durham, all in the general area of interferometric imaging with large ground-based telescopes.
