Willis Room Meeting Friday 6th March 2015. Modern Radio Astronomy and Short Duration Cosmic Bursts – Emily Petroff, Swinburne Uni.
Australian scientists have witnessed the bright flashes of radio waves caused by a cosmic radio burst live for the first time.
Emily Petroff, a PhD student at the Swinburne University of Technology, was lucky enough to see what no astronomer has ever seen before. “It was really exciting, it was something we had been waiting for for a while,” Ms Petroff said.
“We set up a real time system in March last year, and we had been hoping for a while that we would find one. So to have one pop up while we were observing was just really exciting.” A fast radio burst is a quick flash of radio waves that lasts just milliseconds. Even though it was just observed here on Earth, it happened a long time ago in space.
“The universe is 13 billion years old and we are looking from present day. But the further and further away from us we look, we are looking at light that was emitted longer and longer ago,” Ms Petroff explained.”So when we’re seeing these fast radio bursts, we think that they’re coming from very far away, so billions of light years away.
“The light we’re seeing from them is from a time when the universe was much younger.”
