  • Active nucleus in a post-starburst galaxy: KUG 1259+280 
    Dewangan, G. C; Singh, K. P; Mayya, Y. D; Anupama, G. C (The Royal Astronomical Society, 2000-10)
    We report the discovery of an active nucleus in a post-starburst galaxy, KUG 1259+280, based on its X-ray and optical characteristics. The X-ray source in KUG 1259+280 was detected during a search for ultrasoft sources in ...
  • The diffuse, relic radio source in Abell 85: estimation of cluster-scale magnetic field from inverse Compton X-rays 
    Bagchi, J; Pislar, V; Lima Neto, G. B (Royal Astronomical Society, 1998-05)
    We report the first detection of an inverse Compton X-ray emission, spatially correlated with a very steep spectrum radio source (VSSRS), 0038-096, without any detected optical counterpart, in cluster Abell 85. The ROSAT ...
  • Multifrequency Spectra of EXOSAT Blazars. 
    Ghosh, K. K; Soundararajaperumal, S (University of Chicago Press, 1995-09)
    Blazars have been divided into two groups: radio-selected blazars (RBLs) and X-ray-selected blazars (XBLs). Results of the X-ray spectral analysis of 28 such blazars which were observed with EXOSAT are presented in this ...
  • X-Ray variability of active galactic nuclei in the soft and hard X-Ray bands 
    Chitnis, V. R; Pendharkar, J. K; Bose, D; Agrawal, V. K; Rao, A. R; Misra, R (Institute of Physics, 2009-06)
    We investigate the X-ray variability characteristics of hard X-ray-selected active galactic nuclei (AGNs)—based on Swift/Burst Alert Telescope—in the soft X-ray band using the Rossi X-ray Timing Explorer/All-Sky Monitor ...
