The identification of the strong f-gravity metric with Dirac's atomic metric and the large value of its coupling constant, i.e. Gf 10/sup39 GN (GN being Newtonian constant) provides the physical basis for the large numbers ...

Measurements of changes in phase path/Doppler of HF signals on 5.5 MHz from F-region of the ionosphere are carried-out using coherent pulsed Doppler radar. Preliminary analysis of the data show large deviations in phase ...

We have recently developed a narrow band imager (NBI) using a n air gap based Fabry-P ́erot (FP) interferometer at the Indian Institute of Astrophysic s, Bangalore. Narrow band imaging is achieved by using an FP ...

An imaging Fabry-Perot interferometer was designed and used for coronal observations in the green line (FeXIV) 5303 Armstrong. The observations were carried our at Nim Ka Thana, Rajasthan, India during the total solar ...

The Indian Institute of Astrophysics is a premier national institute of India for the study of and research into topics pertaining to astronomy, astrophysics and related subjects. The Institute’s main campus in Bangalore ...

The results from work done to extend the Johnson-Cousins BVRI photometric standard sequence to faint levels of V~21 mag in compact fields is presented. Such calibration and extension of sequences is necessary to fill a ...

Three Galactic star forming regions in the northern sky, viz., associated with W3(OH), S209 and S187 have been simultaneously mapped in two trans-IRAS far infrared (FIR) bands centered at ~ 140 and 200 μm using the TIFR ...
