As an example, Soon after completing his doctorate and accepting a faculty position at Stanford, Govind and Bina Swarup returned to India so that Govind could launch a radio astronomy program at the Tata Institute of Fundamental Research in what was then still known as Bombay (present-day Mumbai). The Ooty Radio Telescope was used mainly to measure the positions and angular sizes of faint radio galaxies and quasars. error by 14 arcseconds, and a good occultation position was not derived until John Bolton is the man on the extreme right of the group photograph (CSIRO RAIA: 2842-43), The Ooty Radio Telescope, consisting of the 530-m long and 30-m wide cylindrical parabolic antenna placed along a north-south sloping hillside at an angle of 11.35° so that its axis of rotation was parallel to that of the Earth (Courtesy TIFR Archives), A view looking south-west across the two Potts Hill water reservoirs in 1953, showing Christiansen's solar grating arrays along the banks of the eastern reservoir. This new science was born when Karl Jansky (1933) serendipitously discovered that radio emission in the form of radio noise was being emitted from the direction of the Milky Way our galaxy. But it had a special place in Govind’s heart because back in 1955 he and fellow Colombo Plan student, R. Parthasarathy, had reconfigured this as a 500 MHz grating array and used it to search for evidence of solar limb brightening. The 50th anniversary since the Ooty Radio Telescope (ORT) first observed occultation of a radio source by the moon was celebrated at the Radio Astronomy Center (RAC) here on Tuesday.Scientists, profes Between 1953 and 1955 Govind served what was, During the period 1946–1961 Australia was one of the world’s leading nations in radio astronomy and played a key role in its development.
