R; Murthy, S; Kulkarni, R; Meena, G; Babu, V. C; Postma, J (SPIE--The International Society for Optical Engineering, 2014-07)
    ASTROSAT is India’s first astronomy satellite that will carry an array of instruments capable of simultaneous observations in a broad range of wavelengths: from the visible, near ultraviolet (NUV), far-UV (FUV), soft X-rays ...
  • Energy dependence of x-ray pulse profile of the crab pulsar 
    Mukerjee, K; Agrawal, P. C; Paul, B; Rao, A. R; Vahia, M. N; Yadav, J. S; Seetha, S; Kasturirangan, K (Astronomical Society of India, 1999)
    We obtained pulse profiles of Crab pulsar in 4 different X-ray energy bands between 2 and 30 keV. We found that all the profiles in these energy ranges show two peaks occurring at the same phase joined by a lower but non ...
  • Gamma ray analysis in planetary mapping 
    Yadav, J. S; Arnold, J. R (Astronomical Society of India, 1993)
    n this work, we present ways to improve the analysis procedure for high resolution gamma ray planetary mapping. This study is aimed at providing better analysis procedures for the Gamma Ray Spectrometer (GRS) experiment ...
  • Multiwavelength studies of galactic black-hole candidates 
    Yadav, J. S (Astronomical Society of India, 2001)
    One of the Galactic Black-hole Candidates GRS 1915+105 has shown spectacular variability on various time scales in X-ray, Infrared (IR) and Radio wavelengths and has been extensively studied in multiwavelengths during last ...
  • Observations of sub-iron (Sc-Cr) to iron (Fe) abundance ratios in the low energy (30-300 MeV/N) galactic cosmic rays in Spacelab-3 experiment and their implications 
    Biswas, S; Durgaprasad, N; Singh, R. K; Vahia, M. N; Yadav, J. S; Dutta, A; Goswami, J. N (Astronomical Society of India, 1993)
    The Spacelab-3 cosmic ray experiment Anuradha was used to measure the sub-iron (Sc-Cr) to iron abundance ratios in the low energy galactic cosmic rays. Measurments made at four different depths of the detector yielded the ...
  • Study of two pulsars with the Indian X-ray Astronomy Experiment 
    Mukerjee, K; Agrawal, P. C; Paul, B; Rao, A. R; Yadav, J. S; Seetha, S; Kasturirangan, K (Astronomical Society of India, 2000)
    The X-ray pulsars Cep X-4 and 4U 1907+09 were observed with the Indian X-ray Astronomy Experiment (IXAE). Observations of Cep-X4 were made during the declining phase of its latest 30 days outburst in 1997, July-August. The ...
  • X-ray bursts from GRS 1915+105 observed with IXAE 
    Yadav, J. S; Agrawal, P. C; Paul, B; Rao, A. R; Vahia, M. N; Seetha, S; Kasturirangan, K (Astronomical Society of India, 1999)
    The light curves of the galactic superluminal X-ray transient source GRS1915+105 observed with the pointed proportional counters (PPC) of Indian X-ray Astronomy Experiment (IXAE)on board IRS-P3 have revealed the presence ...
