Epoch of Reionisation

Project lead: Dr Cathryn Trott

Project members: Assoc. Prof. Randall Wayth, Dr Steven Murray, Dr Chris Jordan, Ronniy Joseph

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.
