Dear colleagues,

I would like to draw your attention to a CSIRO Early Research Career (CERC) postdoctoral fellowship for which we are accepting applications. Please forward it to those interested.

The CERC Fellow will develop new and independent image reconstruction methods based on deep learning methods and the theory of interferometry to determine the spacetime warping and morphology around the event horizons of black holes. A planet-sized network of telescope arrays using Very Long Baseline Interferometry (VLBI) is needed to image close in on the event horizons of supermassive black holes, which is extremely challenging because the telescopes must be accurately calibrated for delays and attenuations in the signal paths, and the spatial information sampled by the telescopes contains only sparse and incomplete information. The independent end-to-end image reconstruction technique addressing these challenges will be applied to real data obtained from VLBI networks, including primarily the recent and famous example of the supermassive black holes at the centres of our Milky Way and M87 galaxies by the Event Horizon Telescope (EHT). This independent approach to interferometric imaging will provide a powerful constraint on the structure of spacetime warping near black holes. It will be instrumental in testing fundamental physics such as the theory of General Relativity and will also reveal the relativistic astrophysics at the black hole site. In parallel, this project will benefit both radio astronomy and deep learning, computational astrophysics in general, as well as interferometric imaging problems in other domains such as medical imaging and seismology. The CERC Fellow will work in close collaboration with the principal investigator Dr. Nithyanandan Thyagarajan (CSIRO Space & Astronomy), and co-principal investigators Dr. Ivy Wong (CSIRO Space & Astronomy) and Dr. Foivos Diakogiannis (CSIRO Data61) and have the opportunity to utilise state-of-the-art GPU infrastructure both at CSIRO and National facilities like Pawsey Supercomputing Centre's High Performance Computing facility, Setonix, for this project, giving a competitive advantage.

CSIRO Early Research Career (CERC) Postdoctoral Fellowships provide opportunities to scientists and engineers who have completed their doctorate and have less than three years of relevant postdoctoral work experience. These fellowships aim to develop the next generation of innovative future leaders.

Applications close 31 August 2023 (11 PM AEST).
