  • 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 (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 ...
  • A multiwavelength study of the dual nuclei in Mrk 212 
    Rubinur, K; Kharb, P; Das, M; Rahna, P. T; Honey, M; Paswan, A; Vaddi, S; Murthy, J (Oxford University Press on behalf of the Royal Astronomical Society, 2021-01)
    We present radio observations of the galaxy merger remnant Mrk 212 with the Karl G. Jansky Very Large Array (VLA) and the upgraded Giant Meter Radio Telescope (uGMRT). Mrk 212 has two previously known radio sources associated ...
  • Simultaneous X-ray/UV Observations of Ultraluminous X-ray Source Holmberg II X-1 with Indian Space Mission Astrosat 
    Vinokurov, A; Atapin, K; Bordoloi, O. P; Sarkisyan, A; Kashyap, U; Chakraborty, M; Rahna, P. T; Kostenkov, A; Solovyeva, Y; Fabrika, S; Safonova, M; Gogoi, R; Sutaria, F. K; Murthy, J (Springer, 2022-09)
    We present the results of eight epochs of simultaneous UV and X-ray observations of the highly variable ultraluminous X-ray source (ULX) Holmberg II X-1 with AstroSat—Indian multiwavelength space satellite. During the ...
  • 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 ...
  • Study of star formation in dual nuclei galaxies using UVIT observations 
    Rubinur, K; Das, M; Kharb, P; Yadav, J; Mondal, C; Rahna, P. T (Oxford University Press on behalf of Royal Astronomical Society., 2024-03)
    We have used the Ultraviolet Imaging Telescope (UVIT) aboard AstroSat to study star formation in a sample of nine dual nuclei galaxies with separations <≈ 11 kpc, which is an expected outcome of galaxy mergers. To minimize ...
  • 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 ...
