Research

Davis designed electronics to use the radio-linked Mark II and Mark III telescopes as Jodrell Bank's first phase-stable radio interforemeter, over a distance of . This was used to measure radio source positions to an accuracy of 100 milliarcseconds; it also enabled longer observation times on sources than before, which led to the measurement of radio emission from
Cygnus A Cygnus A ( 3C 405) is a radio galaxy, one of the strongest radio sources in the sky. Discovery and Identification A concentrated radio source in Cygnus was discovered by Grote Reber in 1939. In 1946 Stanley Hey and his colleague James Phillip ...
