CSIRO Early Research Career (CERC) Postdoctoral Fellowships provide opportunities to scientists and engineers who have completed their doctorate and have no more than three years of relevant postdoctoral work experience. These fellowships aim to develop the next generation of future science leaders.
The Postdoctoral Fellow will build and deploy a sensitive spectral radiometer to detect the redshifted 21 cm radio signal from neutral hydrogen during the Cosmic Dawn. They will commission and observe with the new radiometer at the Square Kilometre Array (SKA) site in Western Australia before deploying to more remote sites at land and sea. Advanced mathematical statistical analysis will be required to detect and measure weak 21 cm signals in the recorded spectra. The challenge is in the necessary precision calibration of the instrument and the development of algorithms to detect weak spectral signatures predicted by cosmology. The cosmic signatures must be carefully separated from the much brighter radio emissions of our Galaxy and our built environment.
Discovering the physics of the emergence of first stars and ultra-faint galaxies from primordial gas is a key goal of modern astrophysics and the Square Kilometre Array. Single-antenna radiometer detection of cosmic dawn is a complementary effort. It is a first step that will pave the way for more detailed studies with the SKA-Low that is being built in Western Australia. At the project’s conclusion, the Postdoctoral Fellow will be empowered with the theoretical understanding and the experimental experience necessary to lead key science with SKA-Low.
