Professor John Evan Baldwin has worked at the Cavendish Astrophysics Group (formerly Mullard Radio Astronomy Observatory) since 1954. He played a pivotal role in the development of Radio Astronomy, and later astronomical optical interferometry and lucky imaging. He made the first maps of the radio emission from the Andromeda Galaxy and the Perseus Cluster, and measured the properties of many active galaxies. In 1985 he performed the first Aperture Masking Interferometry observations, and then lead the construction and operation of the Cambridge Optical Aperture Synthesis Telescope, and helped develop the lucky imaging method. In 2000 he was awarded the Jackson-Gwilt Medal for his technical contributions to the fields of interferometry and aperture synthesis. The Cavendish Laboratory is Cambridge Universitys Department of Physics, and is part of the universitys School of Physical Sciences. ...

Microwave image of 3C353 galaxy at 8. ... Optical interferometry is a technique of interferometry combining light from multiple sources in an optical instrument in order to make various precise measurements. ... The best 1% of exposures of the 0. ... This image is a Galaxy Evolution Explorer observation of the large galaxy in Andromeda, Messier 31. ... An active galaxy is a galaxy where a significant fraction of the energy output is not emitted by the normal components of a galaxy: stars, dust and interstellar gas. ... 1985 is a common year starting on Tuesday of the Gregorian calendar. ... a) shows a simple experiment using an aperture mask in a re-imaged aperture plane. ... COAST, the Cambridge Optical Aperture Synthesis Telescope, is a multi-element optical interferometer with baselines of up to 100 metres, designed to observe stars with angular resolution as high as one thousandth of one arcsecond (much higher resolution than can be obtained with individual telescopes such as the Hubble Space... The best 1% of exposures of the 0. ... This article is about the year 2000. ... The Jackson-Gwilt Medal of the Royal Astronomical Society has been awarded regularly since 1897 for the invention, improvement, or development of astronomical instrumentation or techniques; for achievement in observational astronomy; or for achievement in research into the history of astronomy. ... Interferometry is the applied science of combining two or more input points of a particular data type, such as optical measurements, to form a greater picture based on the combination of the two sources. ... Aperture synthesis is a type of interferometry that mixes signals from a collection instruments to produce measurements having the same angular resolution as an instrument the size of the entire collection. ...
