Unlocking Cosmic Mysteries with the Invisible Radio Universe

By Hamsa Padmanabhan on 05 March, 2020

The epoch of 'Cosmic Dawn', when the first stars and galaxies were born, about a hundred million years after the Big Bang --- is considered the 'final frontier' of research in cosmology today. Observations at radio frequencies have opened up very exciting prospects for studying the evolution of the universe from its earliest stages to the present time. Unprecedented amount of data from the biggest radio facilities around the world will soon help to answer fundamental questions about our cosmos: from a deeper understanding of Einstein's theory of gravity, to whether we are alone in this vast expanse of universe. I will discuss the groundbreaking progress being made in this fascinating field in Canada and elsewhere.
