  • Application of neural network for the gamma-hadron discrimination 
    Maneva, G. M; Temnikov, P. P (Astronomical Society of India, 2002)
    Artificial Neural Network (ANN) method is applied for the analysis of raw data from the gamma ray CELESTE experiment. Our preliminary results show that, in the energy range 30-300 GeV, a good discrimination between showers ...
  • Appreciation of the late Mr. R. J. Pocock, B. A., B.Sc., F.R.A.S. 
    Evershed, J (Astronomical Society of India, 1918)
  • Approaching gravitation by quantum gravity with matter near four dimensions 
    Elizalde, E; Odintsov, S. D; Romeo, A (Astronomical Society of India, 1997)
    The phase structure and infrared (IR) behavior of higher-derivative quantum gravity (QG) near (but below) four dimensions, with a few different matter theories, shows remarkable properties. Models of this sort can be ...
  • An approximate method of computing precision in certain cases 
    Chatwood, A. B (Astronomical Society of India, 1914-04)
  • Are pulsars strange? 
    Kapoor, R. C; Shukre, C. S (Astronomical Society of India, 2001)
    Pulsar radio pulses are made up of the so called core and conal components. A remarkably precise relation for core component widths, found observationally, in effect specifies the size of the polar cap on pulsars. Inclusion ...
  • ARIES imaging polarimeter 
    Rautela, B. S; Joshi, G. C; Pandey, J. C (Astronomical Society of India, 2004-09)
    An Imaging Polarimeter has been fabricated for use with liquid- N2 cooled CCD camera and is designed to suit 104-cm Sampurnanand telescope with an f/13 focus at Aryabhatta Research Institute of Observational Sciences ...
  • Artificial Neural Network-based Image-cleaning Method for Atmospheric Cerenkov Imaging Telescopes 
    Dhar, V. K; Tickoo, A. K; Kaul, M. K; Kaul, C. L; Rannot, R. C; Yadav, K. K; Dubey, B. P; Koul, R (Astronomical Society of India, 2003)
    A novel image-cleaning method, based on the utilization of Artificial Neural Network (ANN) is shown here to `correctly' select more pixels in a Cerenkov image than in the conventional approach.
  • Aryabhata - Eight months of Life in Orbit 
    Rao, U. R; Kasturirangan, K (Astronomical Society of India, 1975-12)
  • Aryabhata I, His Life and His Contributions 
    Ansari, S. M. R (Astronomical Society of India, 1977-03)
    After Recalling a few historical facts concerning Aryabhata`s life and time we list his three known works out of which the only one extant presently is Aryabhatiya. The content of the various chapters of this treatise on ...
  • Aspects of prehistoric astronomy in India 
    Kameswara Rao, N (Astronomical Society of India, 2005-12)
    Some archeoastronomical aspects regarding the development of observational astronomy in India during prehistoric times are described. A plea is made for the preservation of megalithic monuments of possible astronomical ...
  • An assessment of far-infrared measurements and their processing 
    Ghosh, S. K; Das, B; Rengarajan, T. N; Verma, R. P (Astronomical Society of India, 1993)
    Three image processing schemes, used for generating far-infrared (FIR) astronomical maps have been compared for their relative merits. Two of these schemes based on the maximum entropy method (MEM) have been developed at ...
  • Association of Coronal holes with large scale Solar Magnetic fields 
    Shelke, R. N; Pande, M. C (Astronomical Society of India, 1984-12)
    Association of coronal holes with large scale solar magnetic fields has been investigated. It is concluded that coronal holes always form in the large unipolar megnetic field patterns, and no specific polarity rule holds ...
  • Association of solar flares with twisting of magnetic neutral lines 
    Uddin, W; Pande, M. C; Shelke, R. N (Astronomical Society of Indian, 1986-06)
    A 'twisting index' is defined, assuming that flares tend to occur in highly sheared magnetic fields which also lead to a twisting of magnetic neutral lines in complex active regions. The correlation of this twisting index ...
  • Asteroseismological calibration of open clusters 
    Audard, N; Brown, T. M; Christensen-Dalsgaard, J; Frandsen, S; Kjeldsen, H (Astronomical Society of India, 1996)
    Combining classical and seismological data permits one to perform a calibration of stars, and therefore to improve the estimate of their fundamental parameters. We present preliminary results of the calibration of stars ...
  • Asteroseismology of white dwarf stars with medium size telescopes 
    Marar, T. M. K; Seetha, S; Ashoka, B. N (Astronomical Society of India, 1998)
  • Astrometry of Comet Halley during the 1985-86 apparition 
    Bagare, S. P; Scaria, K. K (Astronomical Society of Indian, 1988)
    Photographs of Comet Halley were obtained using the 1-m telescope of the Vainu Bappu Observatory, Kavalur, during the 1985-86 apparition, and astrometric measurements carried out. The details of the observations and the ...
  • Astronomical gamma-ray lines predicting probable gamma-emitter nucleosynthesis sites as explosive events 
    Bardoloi, I; Barua, M. M (Astronomical Society of India, 2002)
    Astronomical gamma-ray (?) lines with energy 0.5 - 15 MeV have been interpreted as due to e+ - e- annihilation and decay and de-excitation of the excited nucleosynthesis yields produced in some explosive sites and then ...
  • Astronomical masers 
    Chandra, S (Astronomical Society of India, 1996)
  • Astronomical notes 
    Roy, J. C (Astronomical Society of India, 1911-12)
  • Astronomical notes 
    Chakraburtty, K. N (Astronomical Society of India, 1918)
