  • The 16th International Cosmic Ray Conference 
    Daniel, R. R (Astronomical Society of India, 1979-12)
  • CCD imaging of gamma ray burster fields 
    Bhargavi, S. G; Cowsik, R; Pati, A. K; Sagar, R (Astronomical Society of India, 1998)
  • Flat Spectrum Gamma Ray Burst Afterglows 
    Bhattacharya, D (Astronomical Society of India, 2001)
    Temporal behaviour of GRB afterglow light curve is derived for the case where the electron energy distribution is relatively hard, with the power-law index p lying between 1.0 and 2.0. It is shown that the expected behaviour ...
  • Gamma ray bursts at high energies : detection ranges and event rates 
    Shanthi, K; Kaul, C. L; Kaul, R. K; Tickoo, A. K; Bhat, C. L (Astronomical Society of India, 2002)
    The Gamma-Ray Burst (GRB) detection rates at energies ? 20GeV, have been estimated for the 3 atmospheric Cerenkov telescope systems of the GRACE project at Mt. Abu, under the assumption that the bursts have a cosmological ...
  • High energy universe -- Satellite missions 
    Krishan, V (Indian Academy of Sciences, 2000-12)
    A variety of satellite missions to observe the high energy universe are currently operating and some more with more versatility and capability are on the anvil. In this paper, after giving a brief introduction to the ...
  • Limits on rotation-induced characteristics of radiation from stable rapidly rotating neutron stars 
    Datta, B; Kapoor, R. C (The American Astronomical Society, 1988-08)
    Results are presented of a study of frequency shifts in radiation from the surface of rapidly rotating neutron stars and rotation-induced spectral line broadening as a function of their mass. It is found that, despite large ...
  • Optical counter-parts of Gamma Ray Bursts 
    Bhat, P. N (Astronomical Society of India, 2000)
    Gamma Ray Bursts (GRB'S) being the most energetic astronomical phenomena known to date still pose a formidable challenge to astronomers. The BATSE on board the Compton Observatory (CGRO) launched in 1991, has shown that ...
  • Rapid searches for counterparts of GRB 930131 
    Schaefer, Bradley. E; Barthelmy, Scott. D; Palmer, David. M; Cline, Thomas. L; Hurley, Kevin. C; Sommer, Michael; Boer, Michel; Niel, Michel; Fishman, Gerald. J; Kouveliotou, Chryssa; Meegan, Charles. A; Coe, M. J; Elmegreen, Bruce. G; McNamara, Bernard. J; Harrison, Thomas; Owens, Alan; Sollee, Neyle; Stull, John; Palermiti, Michael; Schwartz, Richard; Brooks, Jack; Vanderspek, Roland; Ricker, George. R; Krimm, Hans. A; Wenzel, Wolfgang; Greiner, Jochen; Hudec, Rene; Novak, Miroslav; Borovicka, Jiri; Predota, Miroslav; Bailyn, Charles. D; Hanlon, Lorraine. O; Bennett, K; Spoelstra, Titus. A. Th; Smette, Alain; Pedersen, Holger; Florentin, Ralph; Pollas, Christian; Steinle, Helmut; Schramm, K. J; Iyengar, K. V. K; Prabhu, T. P (American Astronomical Society, 1994-02)
    A fading counterpart to a gamma-ray burst (GRB) would appear as a point source inside a GRB error region soon after the burst which dims on a timescale from minutes to days. The favorable circumstances of the burst GRB ...
  • Search for optical bursts from the gamma ray burst source GBS 0526-66 
    Seetha, S; Sreenivasaiah, K. V; Marar, T. M. K; Kasturirangan, K; Rao, U. R; Bhattacharyya, J. C (NASA/STI, 1985-08)
    Attempts were made to detect optical bursts from the gamma-ray burst source GBS 0526-66 during Dec. 31, 1984 to Jan. 2, 1985 and Feb. 23 to Feb. 24, 1985, using the one meter reflector of the Kavalur Observatory. Jan. 1, ...
