St. Thomas's Hospital Armorial Bearings

whole matter is dealt with in full. From "it I reproduce the following :? It ia probably known to most St. Thomas's men past and present that for some years St. Thomas's Hospital has been using an heraldic device supposed to be the arms of the hospital. Eighteen months ago the writer being unable to find any authority for this device, he and the Secretary (G. Q. Roberts, C.B.E., M.A.) spent som...

The Virtual Astronomical Observatory: Re-engineering access to astronomical data

TheUSVirtual Astronomical Observatorywas a software infrastructure anddevelopment project designed both to begin the establishment of an operational Virtual Observatory (VO) and to provide the US coordination with the international VO effort. The concept of the VO is to provide the means by which an astronomer is able to discover, access, and process data seamlessly, regardless of its physical ...

Integrated optics for astronomical interferometry - I. Concept and astronomical applications

We propose a new instrumental concept for long-baseline optical single-mode interferometry using integrated optics which were developed for telecommunication. Visible and infrared multi-aperture interferometry requires many optical functions (spatial filtering, beam combination, photometric calibration, polarization control) to detect astronomical signals at very high angular resolution. Since ...
