  • Cosmic gamma ray bursts -- recent developments 
    Vahia, M. N (Astronomical Society of India, 1993)
    The Gamma Ray Bursts (GRB) have been observed for the last 20 years by a large number of satellites. However, till recently, comprehensive analysis was difficult in view of varying techniques used by different satellites. ...
  • Limit on the average redshift of Gamma Ray Bursts from evolving galaxies 
    Jain, D; Panchapakesan, N; Mahajan, S; Bhatia, V. B (Astronomical Society of India, 2000)
    Identification of gravitationally lensed Gamma Ray Bursts (GRBs) in the BATSE 4B catalog can be used to constrain the average redshift <z> of the GRBs. Here we calculate an upper limit to <z>, independent of the physical ...
  • Nonpotential magnetic fields at sites of gamma-ray flares 
    Hagyard, M. J; Venkatakrishnan, P; Smith, J. B. Jr (American Astronomical Society, 1990-06)
    The relation between the degree of nonpotentiality of photospheric magnetic fields and the occurrence of gama-ray flares is examined to determine whether there are special signatures of the stressed fields for this type ...
  • The synthesis of Al-26 during combined hydrogen and helium-burning reactions 
    Goswami, A; Ramadurai, S; Duorah, H. L (Springer Netherlands, 1992-02)
    The synthesis of Al-26 during combined hydrogen and helium-burning processes in high temperature and density conditions is studied. The possible sites for these processes are believed to be the neutron star surfaces where ...
  • Thermal Gravitational Waves 
    Sivaram, C; Arun, K (Bentham Open, 2011-08)
    There is a lot of current interest in sources of gravitational waves and active ongoing projects to detect such radiation, such as the LIGO project. These are long wavelength, low frequency gravitational waves. LISA would ...
  • Ultra-high energy cosmic rays and prompt TeV gamma rays from gamma ray bursts 
    Bhattacharjee, P; Gupta, N (Indian Academy of Sciences, 2004-03)
    Gamma ray bursts (CRBs) have been proposed as one possible class of sources of the ultrahigh energy cosmic ray (UHECR) events observed up to energies greater than or similar to 10(20) eV. The synchrotron radiation of the ...
