Epoch of Reionisation
Project lead: Dr Cathryn Trott
Project members: Assoc. Prof. Randall Wayth, Dr Steven Murray, Dr Chris Jordan, Dr Ben McKinley, Ronniy Joseph, Bella Nasirudin
The Epoch of Reionisation project explores the first billion years of the Universe, as probed through the redshifted emission line of neutral hydrogen gas. Studying the spatial and temperature distribution of the neutral hydrogen gas between the first galaxies provides key insights into the growth of structure at the Cosmic Dawn, and the first sources of ionising radiation in the Universe. We are exploring this signal with the Murchison Widefield Array (MWA), and future Square Kilometre Array (SKA).
Two different possible evolutionary paths of neutral gas in the Universe. These paths are being probed by low-frequency radio telescopes, such as the Murchison Widefield Array. Image courtesy of Andrei Mesinger (SNS, Italy).
Student projects are available in the following areas: data processing, statistical algorithm development, foreground modelling, instrument design.
CIRA comprises one half of the International Centre for Radio Astronomy Research (ICRAR) Joint Venture with The University of Western Australia, as well as being a node of the ARC Centre of Excellence for All-sky Astrophysics (CAASTRO) and ARC Centre of Excellence for All-sky Astrophysics in 3 Dimensions (ASTRO 3D). CIRA researchers maintain excellent linkages with these and other national and international groups, and, in addition CIRA has excellent access to the new $80M Pawsey Supercomputing Centre.
