  • Speckle interferometric observations of close binary stars 
    Saha, S. K; Chinnappan, V; Yeshwanth, L; Anbazhagan, P (Astronomical Society of India, 2002-09)
    Speckle interferometric technique is employed to record a series of hundreds of short-exposure images of several close binary stars with sub-arc second separation through a narrow band filter at the Cassegrain focus of ...
  • Speckle interferometric observations of the collision of comet Shoemaker-Levy 9 with Jupiter 
    Saha, S. K; Rajamohan, R; Vivekananda Rao, P; Sunder, G. S; Swaminathan, R; Lokanandham, B (Astronomical Society of India, 1997)
    Speckle interferometric technique has been used to obtain a series of short exposure images of the collision of comet Shoemaker-Levy 9 with Jupiter during the period of July 17-24, 1994 using the Nasmyth focus of 1.2 meter ...
  • Speckle interferometry at IIA and elsewhere: An overview 
    Venkatakrishnan, P; Saha, S. K; Shevgaonkar, R. K (Tata Institute of Fundamental Reserach, 1988)
    The technique of speckle interferometry, used for compensating the blurring effects of the earth's atmosphere, is briefly outlined. The achievements of this technique by different groups in the world are listed. We then ...
  • Speckle interferometry technique for astronomical observations 
    Saha, S. K (The Optical Society of India, 2003)
  • SS 433: results of a recent multiwavelength campaign 
    Chakrabarti, S. K; Anandarao, B. G; Pal, S; Mondal, S; Nandi, A; Bhattacharyya, A; Mandal, S; Sagar, R; Pandey, J. C; Pati, A. K; Saha, S. K (Royal Astronomical Society, 2005-09)
    We conducted a multiwavelength campaign in 2002 September-October, to observe SS 433. We used the Giant Meter Radio Telescope for radio observations, the Physical Research Laboratory Infrared Telescope at Mt Abu for infrared ...
  • Toward a revival of stellar intensity interferometry 
    LeBohec, S; Barbieri, C; Willem-Jan, de W; Dravins, D; Feautrier, P; Foellmi, C dric; Glindemann, A; Hall, J; Holder, J; Holmes, R; Kervella, P; Kieda, D; Le Coarer, E; Lipson, S; Malbet, F; More, S. B; Nu ez, P; Ofir, A; Ribak, E; Saha, S. K; Schoeller, M; Zhilyaev, B; Zinnecker, H (SPIE The International Society for Optical Engineering, 2008)
    Building on technological developments over the last 35 years, intensity interferometry now appears a feasible option by which to achieve diffraction-limited imaging over a square-kilometer synthetic aperture. Upcoming ...
  • Waves and oscillations in nature: an introduction 
    Satya Narayanan, A; Saha, S. K (CRC Press, 2015)
    Waves and oscillations are found in large scales (galactic) and microscopic scales (neutrino) in nature. Their dynamics and behavior heavily depend on the type of medium through which they propagate.Waves and Oscillations ...
