  • Advancements in space-based NUV spectrography: Precision fabrication and evaluation of an optical slit using optical lithography and deep reactive ion etching 
    Binukumar, G; Bharat Chandra, P; Safonova, M; Sultana, Sabiha; Yadhukrishnan, S. V; Nawaz, N; Shubham Jankiram, Ghatul; Jain, Shubhangi; Mahesh Babu, S; Mohan, Rekhesh; Murthy, J (SPIE - Society of Photo-Optical Instrumentation Engineers, 2024-08)
    This article describes the development of a space-based near-Ultraviolet (NUV) spectrograph, focusing on the intricate fabrication and meticulous evaluation of an optical slit employing advanced techniques such as optical ...
  • 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 ...
  • 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. ...
  • 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 ...
