Limited travel funding.
The Australian Research Council (ARC) Centre of Excellence for All Sky Astrophysics in 3 Dimensions (ASTRO 3D) spans six (6) Australian universities, three (3) national infrastructure facilities, and seven (7) international partner institutions. ASTRO 3D combines Australia's leading optical, infrared and radio telescope technologies with sophisticated theoretical simulations and ambitious new data intensive science techniques to build a comprehensive picture of the evolution of matter, the chemical elements, and ionizing radiation in the Universe from the Epoch of Reionization (EoR) to the present day.
Curtin University is part of the International Centre for Radio Astronomy Research (ICRAR), a Joint Venture partnership with the University of Western Australia, which is also an ASTRO 3D node. This PhD position is offered at the Curtin University node, where the primary science program is The Epoch of Reionization, led by Assoc. Professor Cathryn Trott.
PhD projects on offer include:
Understanding ionospheric conditions in MWA EoR data (contact: Dr Chris Jordan, email@example.com)
Variations in the ionosphere are poorly understood, yet have a profound impact on most radio transmissions between Earth and space, and radio astronomy. MWA EoR is in a unique position to further study and understand how and why the ionosphere changes and behaves, which has huge implications for making radio transmissions more reliable into the future.
Measuring the global EoR signal using the MWA and the Moon (contact: Dr Ben McKinley, firstname.lastname@example.org)
Tiny variations in the mean temperature of the sky across the low-frequency radio spectrum provide a means to test our theories describing the evolution of the early Universe. Traditionally, single-dipole antennas have been used to try to detect this weak signal in the presence of bright astronomical foregrounds. In this project, you will develop, test and improve techniques to measure this global temperature using a novel, alternative method, which aims to measure the signal with an interferometer, using the Moon as a thermal reference source.
Eliminating the effect of the ionosphere in MWA EoR data (contact: Dr Chris Jordan, email@example.com)
The detection of the signature from the EoR is an ambitious project, and only by fully characterising our instrument and all intervening signals between us and the EoR do we have a hope to reach it. The ionosphere, despite being in extreme proximity relative to traditional impediments to the EoR detection, affects us in both powerful and subtle ways. Detection and removal of ionospheric effects is thus critical to our detection of the EoR.
The Epoch of Reionization program uses the Murchison Widefield Array and future Square Kilometre Array in Western Australia to detect the sources at the Epoch of Reionization using rest-frame 21cm emission and to compare with the predictions of detailed theoretical simulations. Other ASTRO 3D Science Programs include First Stars, First Galaxies, Galaxy Evolution, ASKAP Surveys, SAMI, GALAH, Data Intensive Science.
