  • Investigating the in-flight performance of the UVIT payload on AstroSat 
    Rahna, P. T; Murthy, J; Safonova, M; Sutaria, F. K; Gudennavar, S. B; Bubbly, S. G (Oxford University Press on behalf of the Royal Astronomical Society, 2017-11)
    We have studied the performance of the Ultraviolet Imaging Telescope payload on AstroSat and derived a calibration of the far-ultraviolet (FUV) and near-ultraviolet (NUV) instruments on board. We find that the sensitivity ...
  • JUDE: an ultraviolet imaging telescope pipelineâ 
    Murthy, J; Rahna, P. T; Sutaria, F. K; Safonova, M; Gudennavar, S. B; Bubbly, S. G (Elsevier B.V, 2017-07)
    The Ultraviolet Imaging Telescope (UVIT) was launched as part of the multi-wavelength Indian AstroSat mission on 28 September, 2015 into a low Earth orbit. A 6-month performance verification (PV) phase ended in March ...
  • Photometric identification of objects from Galaxy Evolution Explorer Survey and Sloan Digital Sky Survey 
    Preethi, K; Gudennavar, S. B; Bubbly, S. G; Murthy, J; Brosch, N (Oxford University Press on behalf of the Royal Astronomical Society, 2014-01-01)
    We have used Galaxy Evolution Explorer (GALEX) and Sloan Digital Sky Survey (SDSS) observations to extract seven band photometric magnitudes for over 80 000 objects in the vicinity of the North Galactic Pole. Although these ...
  • Silicon depletion in the interstellar medium 
    Haris, U; Parvathi, V. S; Gudennavar, S. B; Bubbly, S. G; Murthy, J; Sofia, U. J (IOP Publishing, 2016-07)
    We report interstellar silicon ( Si ) depletion and dust-phase column densities of Si along 131 Galactic sight lines using archival observations. The data were corrected for differences in the assumed oscillator ...
  • The Solar Ultraviolet Imaging Telescope on-board Aditya-L1 
    Murthy, J; Rahna, P. T; Sutaria, F. K; Safonova, M; Gudennavar, S. B; Bubbly, S. G (Current Science Association, 2017-08)
    The Solar Ultraviolet Imaging Telescope (SUIT) is an instrument onboard the Aditya-L1 spacecraft, the first dedicated solar mission of the Indian Space Research Organization (ISRO), which will be put in a halo orbit at the ...
  • A study of the star-forming regions in the spiral galaxy NGC 2336 using the Ultraviolet Imaging Telescope (UVIT) 
    Rahna, P. T; Mousumi Das; Murthy, J; Gudennavar, S. B; Bubbly, S. G (Oxford University Press on behalf of the Royal Astronomical Society, 2018-11)
    We present a far-ultraviolet (FUV) and near-ultraviolet (NUV) imaging study at 1.2 arcsec resolution of recent star formation in the nearby spiral galaxy NGC 2336 using the Ultraviolet Imaging Telescope (UVIT) on-board ...
  • Template-based classification of SDSS-GALEX point sources 
    Anjum, A; Mousumi Das; Murthy, J; Gudennavar, S. B; Rajesh, G; Bubbly, S. G (Indian Academy of Sciences, 2018-10)
    We have classified a sample of 37,492 objects from SDSS into QSOs, galaxies and stars using photometric data over five wave bands (u, g, r, i and z) and UV GALEX data over two wave bands (near-UV and far-UV) based on a ...
