  • JUDE (Jayant’s UVIT Data Explorer) pipeline user manual 
    Rahna, P. T; Murthy, J; Safonova, M (Indian Academy of Sciences, 2021-10)
    We have written a reference manual to use JUDE (Jayant’s UVIT Data Explorer) data pipeline software for processing and reducing the Ultraviolet Imaging Telescope (UVIT) Level 1 data into event lists and images—Level 2 ...
  • 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 ...
  • Proposed UV - optical payload for the Indian astronomy satellite 
    Pati, A. K (Astronomical Society of India, 1999)
    The Ultraviolet Imaging Telescope is a part of the proposed Indian Multiwavelength Astronomy Satellite mission. The primary objective of the UV Imaging Telescope is an all-sky survey in two bands in the wavelength region ...
  • Relative velocities and linewidths in a coronal hole and outside 
    Raju, K. P (Springer Netherlands, 2009-03)
    Relative Doppler velocities and spectral linewidths in a coronal hole and in the quiet Sun region outside have been obtained from Solar and Heliospheric Observatory (SOHO)/Coronal Diagnostic Spectrometer (CDS) observations. ...
  • Solar UV variability 
    Subbaraya, B. H (Astronomical Society of India, 1998)
    The ultraviolet part of the solar spectrum is unique. Sandwiched between the relatively stable visible radiation and the highly variable energetic radiation short of 1000Ǻ, the EUV and the X-rays, it exhibits a small but ...
  • Spectral Lines in FUV and EUV for Diagnosing Coronal Magnetic Field 
    Raveena, Khan; Nagaraju, K (Springer Nature, 2022-07)
    The diagnostic capabilities of spectral lines in the far-ultraviolet (FUV) and extremeultraviolet (EUV) wavelength ranges are explored in terms of their Hanle and Zeeman sensitivity to probe the vector magnetic fields in ...
  • Spectroscopic study of amethyst quartz in the ultraviolet and infrared regions 
    Bappu, M. K. V (Indian Association for the Cultivation of Science, 1953)
    In this paper a study is made of the absorption of light in the ultravia!rt end infrared regions in amethyst quartz. In the ultraviolet the presence of the V-band is masked by the presence of iron impurity and it is ...
  • Ultraviolet astronomy with small space telescopes 
    Brosch, N; Gomez De Castro, Ana; Murthy, J; Ribak, E; Behar, E; Balabanov, V (Astronomical Institute of the Slovak Academy of Sciences, 2017-08)
    After describing the present situation with astronomy in the ultraviolet (UV), reviewing a few past and proposed future missions, we present options to develop space missions that have been realized for modest costs. In ...
