  • Multi-wavelength study of blazars using variability as a tool 
    Kaur, Navpreet; Baliyan, Kiran S.; Chandra, Sunil; Sameer; Ganesh, Shashikiran (The Korean Space Science Society, 2016)
    Active galactic nuclei (AGN) are too compact to be resolved by any existing optical telescope facility, making it difficult to understand their structure and the emission processes responsible for their huge energy output. ...
  • Multi-wavelength view of the galactic black-hole binary GRS 1716-249 
    Rout, Sandeep K.; Vadawale, Santosh V.; Aarthy, E.; Ganesh, Shashikiran; Joshi, Vishal; Roy, Jayashree; Misra, Ranjeev; Yadav, J. S. (Springer, 2021-10)
    The origins of X-ray and radio emissions during an X-ray binary outburst are comparatively better understood than those of ultraviolet, optical and infrared radiation. This is because multiple competing mechanisms - emission ...
  • A multiwavelength study of flaring activity in the high-energy peaked BL lac object 1ES 1959+650 during 2015-2016 
    Kaur, Navpreet; Chandra, Sunil; Baliyan, Kiran S.; Sameer; Ganesh, Shashikiran (American Astronomical Society, 2017-09)
    We present the results from a multiwavelength study of the flaring activity in the high-energy peaked BL Lac object 1ES 1959+650 during 2015 January–2016 June. The source underwent two major outbursts, during 2015 March ...
  • NICSPol: a near-infrared polarimeter for the 1.2-m telescope at Mount Abu infrared observatory 
    Aarthy, Esakkiappan; Rai, Archita; Ganesh, Shashikiran; Vadawale, Santosh V. (Society of Photo-optical Instrumentation Engineers, 2019-08)
    Near infrared camera spectrograph and polarimeter (NICSPol) is a near-infrared (NIR) imaging polarimeter developed for the Near-Infrared Camera and Spectrograph (NICS), one of the backend instruments of the 1.2-m Cassegrain ...
  • Optical intra-day variability in 3C 66A: a decade of observations 
    Kaur, Navpreet; Sameer; Kiran, S. Baliyan; Ganesh, Shashikiran (Oxford University Press Journals, 2017-05)
    We present results based on the observations of the blazar 3C 66A from 2005 November 06 to 2016 February 14 in the BVR and I broad-bands using the 1.2-m telescope of the Mt Abu InfraRed Observatory (MIRO). The source was ...
  • Optical observations and dust modelling of comet 156P/Russell-LINEAR 
    Aravind, K.; Halder, Prithish; Ganesh, Shashikiran; Sahu, Devendra; Serra-Ricart, Miquel; Chambo, Jose J.; Angchuk, Dorje; Sivarani, Thirupathi (Elsevier, 2022-09)
    Comet 156P/Russell-LINEAR is a short period Jupiter family comet with an orbital period of 6.44 years. The results from spectroscopic, photometric, polarimetric observations, and dust modeling studies are presented here. ...
  • Optical variability in IBL S5 0716+714 during the 2013-2015 outbursts 
    Kaur, Navpreet; Baliyan, Kiran S.; Chandra, S.; Sameer; Ganesh, Shashikiran (American Astronomical Society, 2018-07)
    With an aim to explore optical variability at diverse timescales in BL Lac source S5 0716+714, it was observed for 46 nights during 2013 January 14 to 2015 June 01 when it underwent two major outbursts. The observations ...
  • Solar system astronomy with the 3.6-m DOT and the 4-m ILMT 
    Ganesh, Shashikiran; Venkataramani, Kumar; Baliyan, Kiran S.; Joshi, U. C. (Societe Royale des Sciences de Liege, 2018-04)
    Solar system astronomy would be an important field of study with the 3.6-m Devasthal Optical Telescope (DOT) and the 4-m International Liquid Mirror Telescope (ILMT). In this contribution, we highlight the work that could ...
  • Time and phase resolved optical spectra of potentially hazardous asteroid 2014 JO25 
    Venkataramani, Kumar; Ganesh, Shashikiran; Rai, Archita; Hus�rik, Marek; Baliyan, K. S.; Joshi, U. C. (Institute of Physics, 2019-06)
    The asteroid 2014 JO25, considered to be potentially hazardous by the Minor Planet Center, was spectroscopically followed during its close-Earth encounter on 2017 April 19 and 20. The spectra of the asteroid were taken ...
