27.8 The Giant Equatorial Radio Telescope (GERT), grant of US$14,000 for a feasibility study of, and image processing techniques, as summarized belo, 27.9 The Giant Metrewave Radio Telescope: The Offshoot, lasers and optical fibres. After abortive attempts to erect a Giant Equatorial Radio Telescope (GERT) of similar design, first in Kenya and then in Indonesia, in 1984 Govind conceived the idea of constructing a low frequency synthesis radio telescope in India. His early interest in the radio spectrum of hydrogen led to analysis of the hyperfine structure of hydrogen emission and a publication that became a classic paper in the field. on a radio frequency of 327 MHz (a wavelength of 0.92 m) the large 27.4 Radio Astronomy at the National Physical Laboratory, one of the Chris Cross antennas (Krishnan collection). We detected one absorber in the GBT survey from the foreground dwarf galaxy, GQ1042+0747, at an impact parameter of 1.7 kpc and another possible absorber in our follow-up Very Large Array (VLA) imaging of the nearby foreground galaxy UGC 7408. The most significant scientific contributions made by the ORT and the OSRT during the first twenty years are described in Swarup et al. We also detected H I emission from three foreground galaxies including UGC 7408. The GMRT is an array of thirty fully-steerable. In March 2019 the National Centre for Radioastrophysics, held an international conference in Pune to celebrate Govind’s 90th Birthday and the recent major upgrade of the GMRT. 2005. electronics. nationally-recognized leader in the field of solar radio astrono, During meetings of the American Astronomical Societ, (which had still not been used), and thereafter to set up, form a radio astronomy group and also to attract others in due, confidential assessments to the authorities i. archives. of 0.16 Successive radio and optical measurements quickly led to the The Ooty Radio Telescope. In 1963 this led to the construction at Kalyan, near Bombay, of India’s first radio telescope, an array of 32 six-feet (1.8-m) diameter parabolic dishes that served as a 610 MHz solar grating interferometer. Govind’s next radio telescope was a solely Indian affair and an ingenious concept that took full advantage of southern India’s geographical location near the Equator. Nobeyama radio observatory: Nagano Prefecture, Japan 17–115 GHz A 45m single-dish short-millimetre telescope, and six 10m telescopes of the Nobeyama Millimetre … watt radio station located ten million kilo meter away in space. This de facto ‘equatorial mounting’ meant that radio sources could be tracked continuously for 9.5 hours every day. It has a coverage of about ± 40‡ in declination δ. It operates at a frequency of 326.5 MHz with a maximum bandwidth of 15 MHz at the front-end. This book examines the ways in which attitudes toward astronomy in Australia, China, India, Indonesia, Japan, South Korea, New Zealand, Taiwan, Thailand and Uzbekistan have changed with the times. University of Southern Queensland, Toowoomba, Australia. The Ooty Radio Telescope, built during 1965–1970, has an ingenious design which takes advantage of India’s location near the Earth’s Equator. Children will love this place & they will get first hand experience about this research center. After a short time back in India, he moved to Harvard University’s Fort Davis Radio Astronomy field station in Texas, USA, and one year later, in September 1957, began a PhD in radio astronomy under the guidance of Professor Ron Bracewell at Stanford University.

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). Although a number of individual antennas were refurbished in 1991, the very survival of remaining elements of this pioneering radio telescope is in jeopardy. The Radio Astronomy group he founded at TIFR was one of the first such groups anywhere in the world. The EW array consisted of thirty-two elements and the nearer N-S array just sixteen elements (CSIRO RAIA: 3475-1), Dr Homi Bhabha (1911-1966), founding Director of the Tata Institute of Fundamental Research, Mumbai (Courtesy TIFR Archives), Ron Bracewell and Govind Swarup examining solar records (Courtesy Stanford University News Service), All figure content in this area was uploaded by Govind Swarup, All content in this area was uploaded by Govind Swarup on Dec 01, 2017, National Centre for Radio Astrophysics, Tata Institute. effectively an ‘apprenticeship’ in radio astronomy while on a Colombo Plan Fellowship at the Commonwealth Scientific and Industrial Research Organisation’s Division of Radiophysics in Sydney, Australia. 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. Govind, you truly are the ‘Father of Indian Radio Astronomy’, and with affection and profound admiration for all that you have achieved in a lifetime devoted to radio astronomy we offer you this paper as an additional—if slightly belated—birthday present. In 1935 Grote Reber, a young amateur radio engineer, constructed a 10 m diameter parabolic dish in his backyard and succeeded to make a map of the Milky Way (Reber 1940). However, such features are not very common in either small or large radio sources.
