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 ...
  • AstroSat view of GRS 1915+105 during the soft state: detection of HFQPOs and estimation of mass and spin 
    Sreehari, H; Nandi, Anuj; Das, Santabrata; Agrawal, V. K; Mandal, Samir; Ramadevi, M. C; Katoch, Tilak (Oxford University Press on behalf of the Royal Astronomical Society, 2020-12)
    We report the results of AstroSat observations of GRS 1915+105 obtained using 100 ks Guaranteed Time during the soft state. The colour–colour diagram indicates a variability class of δ with the detection of high-frequency ...
  • Multiwavelength study of radio galaxy Pictor A: detection of western hotspot in far-UV and possible origin of high energy emissions 
    Gulati, Sanna; Bhattacharya, Debbijoy; Ramadevi, M. C; Stalin, C. S; Sreekumar, P (Oxford University Press on behalf of Royal Astronomical Society, 2023-05)
    A comprehensive study of the nucleus and western hotspot of Pictor A is carried out using AstroSat observations, 13 yr of Fermi, and archival Swift observations along with other published data. We report the first detection ...
  • SoLEXS - A low energy X-ray spectrometer for solar coronal studies 
    Sankarasubramanian, K; Ramadevi, M. C; Bug, M; Umapath, C. N; Seetha, S; Sreekumar, P; Kumar (Astronomical Society of India, 2011)
    A Solar Low-energy X-ray Spectrometer (SoLEXS), a high spectral resolution (≤ 250 eV at 5.9 keV) instrument with soft X-ray energy coverage (≤ 1.5 keV), is being proposed as an additional payload on-board Aditya-1. The ...
