A special lecture for public on the topic Radio Waves from the Early Universe” by Prof. Ravi Subrahmanya, Director, Raman Research Institute, Bengaluru, on May 10 at 5.30 pm at Jawaharlal Nehru Planetarium.
Astronomers see the history of the Universe in light from the distant past.
The wavelength of that light is stretched by the expanding Universe and arrives at our telescopes at long wavelengths. At the longest wavelengths, Radio Astronomers see the Universe to greater distances and hence earlier times and hence closer to the Big Bang. Well before the formation of the first stars and galaxies, when the matter we see in the present day Universe was just gas, and there was no light, the structure of the Universe and the evolutionary history of the Universe of gas is even so visible to Radio Astronomers. We at the Raman Research Institute build imaginative Radio
Telescopes that continue the quest of understanding the precise history of the transformation of gas in the early Universe to the present day galaxies and stars.
