  • 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, ...
  • Instrumentation of "Solar X-Ray Spectrometer" Low Energy Detector (SLD) - Proposed payload onboard Indian satellite 
    Vadher, N. M; Shah, A. B; Rajmal, J; Vats, H. O; Deshpande, M. R; Seetha, S; Murthy; Sharma, R. K; Umapathy (Astronomical Society of India, 2000)
    It is proposed to fly a high spectral and temporal resolution - "Solar X-Ray Spectrometer (SOXS)" onboard Indian satellite. The SOXS will provide the disk integrated flux in the energy range 2 keV-10 MeV. It is composed ...
  • Processing electronics instrumentation for the low energy detector of Solar X-ray Spectrometer (SOXS) experiment 
    Umapathy, C. N; Sharma, M. R; Solanky, C; Kulkarni, R; Shah, A. B; Vadher, N. M; Jain, R; Jain, A. K; Sreekumar, P (Astronomical Society of India, 2001)
  • Simultaneous imaging in optical and near-IR bands 
    Vadher, N. M; Shah, A. B; Shroff, A. J; Joshi, U. C (Astronomical Society of India, 2000)
    It is very important to have simultaneous observations in optical and near IR bands to understand several astrophysical phenomena. One problem is to know the nature of the central engine in blazars, which are in general ...
  • 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 ...
