Ordinary Meeting: "Radio Cosmology: Observing the Invisible Universe"

Friday 16 November 2012 - 8:00pm
Topic: Radio Cosmology: Observing the Invisible Universe
Speaker: Dr James Allison, University of Sydney
Venue: Epping Creative Centre - 26 Stanley Road, Epping
Abstract: Through observations at radio and mm wavelengths, experimental cosmologists use primordial radiation to study the very earliest moments of our Universe. I will discuss the history of radio cosmology, from early theoretical predictions of the Cosmic Microwave Background, through to present day observations using state-of-the-art ground-based and satellite radio telescopes. I will include a description of current research, which use these radio observations as a tool for probing the largest structures in the Universe (massive clusters of galaxies), seen as giant silhouettes against the Cosmic Microwave Background.
Biography: I am an ARC Super Science Fellow at the Sydney Institute for Astronomy in the University of Sydney. I am a member of the science team for the Australian Square Kilometer Array Pathfinder, working on the distribution of neutral hydrogen gas in the Universe. My doctorate involved using a radio telescope to observe microwave radiation from the earliest moments of the Universe.
