Curtin University is ranked in the top 1% universities worldwide (ARWU 2018 and QS World University Rankings 2019), and is placed 20th in the world for universities less than 50 years old (QS Top 50 Under 50 2019). Curtin is WA’s most preferred university, with highly engaged industry-facing partners. A major global player, with well-integrated campuses in Singapore, Malaysia, Mauritius and Dubai.
International Centre for Radio Astronomy Research (ICRAR)
A four-year Research Fellow position is available at the Curtin University node of the International Centre for Radio Astronomy Research (ICRAR) in Perth, Australia. The Research Fellow will work with the Epoch of Reionisation (EoR) project to design, build and undertake science observations and analysis of the global neutral hydrogen signal from the Cosmic Dawn and Epoch of Reionisation with a prototype array of low radio frequency short-spaced dipoles. The project requires a good knowledge of, and experience with astronomical instrumentation and engineering, and scientific observations and data analysis. The Fellow will work with the Murchison Widefield Array EoR team, Curtin Institute of Radio Astronomy (CIRA) engineering staff and existing Global Signal programs to deliver the prototype array, as a science-quality test instrument for larger Global Signal projects. The position is available from January 2019 for a duration of four years.
This Fellow position is supported through an Australian Research Council Future Fellowship program, which aims to unveil signals from the Cosmic Dawn and Epoch of Reionisation through innovative instrumentation and algorithms.
Your new role
The Research Fellow will work with project leader Assoc. Prof. Cathryn Trott and other global signal and instrumentation expertise at CIRA, to perform a global EoR signal experiment using short-spacing leaked total power signal. The Fellow will lead the development of a prototype array of 15-20 closely-space dipoles, with full signal digitisation, including design of the array layout, signal chain and power requirements. Aspects of this instrumentation development will be supported by existing instrumentation and antenna-design expertise at CIRA. The Fellow will then undertake science observations and analysis of data from the array, with the aim to detect global signal power from the first billion years of the Universe. The prototype array will be co-located with the Murchison Widefield Array (MWA) at the Murchison Radioastronomy Observatory, a radio-quiet zone in the Western Australian desert. Cross-correlation measurements with the MWA will allow for system calibration and benchmarking.
The incumbent of this position is expected to have good knowledge of radio astronomy instrumentation and data analysis. Experience with low-frequency radio interferometers, dipole arrays, and/or global signal experiments would be advantageous.
Design and build a prototype dipole array for conducting short-spacing cross-correlation observations of the low-frequency sky, including array layout, signal chain and power requirements
Design and conduct science observations with the prototype array to calibrate the instrument and extract total power signal
Analyse data to extract a global neutral hydrogen signal, or constraints on such, from the Cosmic Dawn and Epoch of Reionisation
Develop and maintain effective relationships with key internal and external stakeholders
Present results in high-quality journals and at relevant workshops and conferences
Supervise undergraduate and HDR students, and contribute to the general EoR Research Group and ICRAR science programs
As a member of the University community, demonstrate the highest possible standards of professional and personal conduct, modelling the University’s Values and Signature Behaviours.
