Cosmologists have now come to a detailed understanding of what our Universe was like as a
child (400,000 years after the Big Bang) and what it is like as an
adult (13.8 billion years later). But what was our Universe like as a

Dr. Adrian Liu, will describe current efforts to use radio telescopes to make pictures of the teenage Universe. He will present a “sneak preview†of breakthrough results that will enlighten and excite us in the next few years.
