Abstract: The eye was the first astronomical instrument, and we still rely heavily on information from the visible light part of the electromagnetic spectrum to understand the universe. In this talk, I’ll discuss how we use radio waves to study the universe and what unique and unexpected information we can learn from radio waves and how we can make pictures of the universe using radio waves. I will also briefly discuss my own research into the first galaxies using radio emission.
