Explore the evolution of galaxies through this comprehensive lecture focusing on the detection of neutral atomic hydrogen in ancient galaxies. Learn how galaxies convert interstellar gas into stars and discover the critical role of atomic hydrogen as the primary fuel for star formation. Follow the 30-year scientific journey that led to the groundbreaking detection of 21 cm line emission from galaxies approximately 9 billion years ago using the Giant Metrewave Radio Telescope (GMRT). Understand the significance of this discovery for modern radio telescopes, including the upcoming Square Kilometre Array, and gain insights into how measuring atomic hydrogen content in early universe galaxies advances our understanding of galactic evolution. Prof. Nissim Kanekar from NCRA, Pune, delivers this fascinating talk as part of the Vignyana Kathegalu science series, bridging decades of astronomical research with cutting-edge discoveries in radio astronomy.
