  • An Astronomical Polarimeter 
    Deshpande, M. R; Joshi, U. C; Kulshrestha, A. K; Banshidar; Vadher, N. M; Mazumdar, H. S; Pradhan, S. N; Shah, C. R (Astronomical Society of India, 1985-06)
    A polarimeter for the study of astronomical objects has been developed and calibrated. Observations of several objects have been made. The polarimeter covers the spectral range from 3150 A to 8500 A in standard N, U, B, ...
  • PRLNIC3 observations of star forming cloud L1340 
    Ganesh, S; Joshi, U. C; Baliyan, K. S; Shah, C. R; Jain, J. K; Rajpurohit, G. S; Sanchawala, K; Saha, A. B (Astronomical Society of India, 2001)
    Due mainly to high extinction in optical, the structure of our galaxy, Milky Way, is not very well understood. The Galactic disk and bulge contain a host of heavily reddened open clusters which are deeply embedded within ...
  • Radio emission as a diagnostic for solar coronal rotation 
    Vats, H. O; Deshpande, M. R; Mehta, M; Shah, C. R; Shah, K. J (Astronomical Society of India, 1999)
    The time series of solar radio emission at 2.8 GHz is analysed using correlation methods. The analysis showed that this type of time series can be used to infer the rotation period of the source (in this case solar corona). ...
  • Study of variability in BL Lac objects 
    Baliyan, K. S; Ganesh, S; Joshi, U. C; Shah, C. R; Vadher, N. M; Deshpande, M. R (Astronomical Society of India, 2001)
    We have monitored some of the BL Lac objects, such as OJ287, Mrk 421, Mrk 501 etc from Mt Abu Infrared Observatory, using optical photopolarimeter, CCD and NICMOS-3 IR array mounted at the Cassegrain focus of the 1.2 m ...
