  • EXOSAT observations of the broad-line radio galaxy 3C 382 
    Ghosh, K. K; Soundararajaperumal, S (University of Chicago Press, 1992-04)
    Results are presented of numerous X-ray observations of the broad-line radio galaxy 3C 382 carried out with Exosat between 1983 and 1985, with emphasis on a major outburst of this galaxy in 1985. During the outburst, both ...
  • EXOSAT observations of the Seyfert 1 galaxy NGC 3516 
    Ghosh, K. K; Soundararajaperumal, S (University of Chicago press, 1991-12)
    This study presents results of the X-ray spectra (0.1-10 keV) of the Seyfert galaxy NGC 3516 on the basis of Exosat observations obtained on four epochs between 1985/308 and 1985/340. The soft X-ray (0.2-2 keV) flux of ...
  • X-ray spectrum (0.1-10 keV) of the broad line radio galaxy - 3C 390.3 
    Ghosh, K. K; Sondararajaperumal, S (The American Astronomical Society, 1991-10)
    Results are presented of observations of the broad-line radio galaxy, 3C 390.3 that were made with Exosat on several occasions between 1984 and 1986 using low- (LE) and medium-energy (ME) detectors. Detailed findings of ...
  • X-ray spectrum of NGC 3783 - Detection of soft excess and an emission line 
    Ghosh, K. K; Soundararajaperumal, S; Kalai Selvi, M; Sivarani, T (EDP Sciences, 1992-02)
    Results of the X-ray (0.1-10 keV) spectral analysis of the Seyfert I galaxy, NGC 3783, which was observed with EXOSAT on three epochs between 1983 and 1985, are presented here. No low energy absorption, intrinsic to the ...
  • X-ray spectrum of the radio-loud quasar PKS 1217 + 023 
    Ghosh, K. K; Soundararajaperumal, S (EDP Sciences, 1991-12)
    A study of the X-ray (0.1-10 keV) spectrum from the radio-loud quasar, PKS 1217 + 023 is presented. This quasar was observed with Exosat on two epochs in January 29 and May 14, 1984. The data were obtained from the Exosat ...
