  • A low cost steerable radio-telescope 
    Sawant, H. S; Neri, J. A. C. F; Fernandes, F. C. R; Cecatto, J. R; Sankararaman, M. R; Faria, C; Stephany, S; Rosa, R. R; Andrade, M. C; Alonso, E. M. B; Ludke, E; Subramanian, K. R; Ramesh, R; Sundararajan, M. S; Ananthakrishnan, S; Swarup, G; Boas, J. W. V; Botti, L. C. L; Moron, C. E; Saito, J. H (Elsevier B. V., 2003)
    We present the technical characteristics of a low-cost radio telescope for solar/non solar observations at decimetric (1200–1700 MHz) and centimetric (2700 and 5000 MHz) wavelengths known as Brazilian Decimetric Array ...
  • A new electronically steerable 1056 dipole array at 327 MHz for the Ooty radio telescope 
    Joshi, M. N; Swarup, G; Bagri, D. S; Kher, R. K (Astronomical Society of Indian, 1988)
    The electronically steerable 1056-element linear dipole array installed on the Ooty radio telescope in 1982 is described. The colinear dipole array consists of 22 subarrays of 48 dipole each and employs a low loss (about ...
  • Observations of Associated H I Absorption in Radio Galaxies and Quasars using GMRT 
    Swarup, G; Sarkar, A (Astronomical Society of India, 2002-09)
    We describe observations and preliminary results of absorption by cold hydrogen gas (H I) associated with six radio galaxies and quasars (Table 1) which may provide valuable information about their host galaxies and ...
  • Proposal for an international institute for space sciences and electronics and for a giant equatorial radio telescope as a collaborative effort of the developing countries 
    Swarup, G (Astronomical Society of India, 1981-12)
    It is proposed to construct a 2 km long and 50 m wide cylindrical radio telescope at a site close to the earth's equator. By placing the long axis of the cylinder in the north-south direction at the equator, its axis of ...
  • Radio Astronomy Centre, Ootacamund 
    Swarup, G (Astronomical Society of India, 1974-03)
  • Search for HI Reionization Epoch in the Early Universe 
    Swarup, G (Astronomical Society of India, 2003)
    One of the most challenging problems in astronomy today is to search for reionization of the neutral hydrogen (HI), which is expected to occur somewhere between redshifts of about 6 to 20. The reionization is likely to ...
  • Southern hemisphere solar radio heliograph 
    Sawant, H. S; Fernandes, F. C. R; Neri, J. A. C. F; Cecatto, J. R; Faria, C; Stephany, S; Rosa, R. R; Andrade, M. C; Ludke, E; Subramanian, K. R; Ramesh, R; Sundrarajan, M. S; Sankararaman, M. R; Ananthakrishnan, S; Swarup, G; Boas, J. W. V; Botti, L. C. L; Moron, C. E; Saito, J. H; Karlicky, M (European Space Agency, 2002-12)
    The Brazilian Decimetric Array (BDA) is being developed at National Institute for Space Research (INPE) as an international collaborative program. Initially, the BDA will operate in the tuneable frequency range of 1.2-1.7 ...
