Astrophysical Plasma by Professor G Srinivasan
Explore the fascinating world of astrophysical plasma in this comprehensive 2-hour lecture by Professor G Srinivasan from the Raman Research Institute. Delve into key concepts such as dielectric screening, dispersion relations, and Faraday rotation. Examine the Earth's ionosphere, pulsar signal dispersion, and de-dispersion techniques. Investigate Cerenkov radiation, its Nobel Prize-winning discovery, and its applications in modern neutrino detectors. Learn about the Milky Way Magnetic Field Mapping Mission and plasma effects on synchrotron intensity. Gain insights into the vast range of densities, temperatures, and magnetic fields found in the universe, from interstellar hydrogen clouds to neutron stars and active galactic nuclei. This lecture, part of the "Random Walk in Astrophysics" summer course, offers a rich exploration of basic physics principles applied to contemporary astronomy.
