A Digital Auto Correlation Spectrometer For Solar Burst Obsevations At Decameter Wavelengths
(Indian Institute of Science, 2006-02-27)
This thesis reports the design, construction, and the initial results obtained from a digital spectrograph for observations of radio burst emission from the Sun. One of the distinct advantages of radio spectral studies of ...
On the Nature Of Propagating MHD Waves In The Solar Atmosphere
One of the most persistent problem in solar physics is the identification of the mechanism that heats the solar corona and accelerates the fast solar wind. Magneto-hydrodynamic (MHD)waves play a crucial role in heating of ...
A Radio Study Of Gas Loss Processes In Nearby Galaxies
The work in this thesis involves detailed multi-frequency radio continuum (from 325 MHz to 15 GHz) and Hi spectroscopic studies of a few represent tative nearby galaxies which are experiencing gas-loss from their disks ...
Prolate Shaped Dark Matter Halo And The Galactic Warp
The physical explanation for the existence of the galactic warp is one of the major research areas in Astronomy. People have proposed various theories but nobody has yet given a convincing explanation. Most of the spiral ...
