Ross Turner is a Lecturer in Physics and ARC Research Fellow at the University of Tasmania. His primary area of research is computational physics with applications in theoretical astrophysics and Antarctic Sciences. He is particularly interested in modelling the physics of jet-inflated lobes emanating from active supermassive black holes (Active Galactic Nuclei; AGN) both to understand the formation history of distant galaxies and as standard rulers in cosmology. He interests in Antarctic Sciences relate to the clustering seismic signals from active glaciers using unsupervised machine learning and developing techniques to explain correlations between climate indicators in the age of big data. Ross is the Tasmanian Chair and Head of Digital Transformation for QueersInScience.

Biography

Ross received his PhD from the University of Tasmania in 2018. He was appointed as an ARC Research Fellow in Mathematical and Computational Geophysics in 2018, and as a Lecturer in 2019. Ross had previously lectured and tutored mathematics and physics units whilst completing his PhD commencing in 2014. Ross has contributed more than ten first-author peer-reviewed publications in astrophysics and computational Earth Sciences, and has won over $2 million in competitive research funding.

Research Themes

Ross’ primary research interest is computational physics with applications in theoretical astrophysics and Antarctic Sciences. This research aligns to the University’s themes of Data, Knowledge and Decisions, and Marine, Antarctic and Maritime. Ross created the RAiSE (Radio AGN in Semi-Analytic Environments) software package to simulate the physics of jet-inflated lobes emanating from active supermassive black holes (Active Galactic Nuclei; AGN), and the RAiSERed (RAiSE Redshift) package to constrain the expansion rate of the universe at the cosmological distances of these objects. He is particularly interested in applying these and other theoretical tools to interpret next-generation large sky surveys such as the Square Kilometre Array and its pathfinders. In Antarctic Sciences, Ross is interested in clustering seismic signals from active glaciers using unsupervised machine learning and developing techniques to explain correlations between climate indicators in the age of big data.

Collaboration

Ross’ external research collaborations include those with colleagues at the Australian Antarctic Division, Curtin University, University of Hertfordshire, University of Western Australia, and CSIRO Astronomy and Space Science.

Ross has successfully led or co-led numerous competitive research proposals including a Legacy Project on the Australia Telescope Compact Array (2016-2020), an ambitious project to observe redshift z=10 galaxies with the Hubble Telescope (2020-2021), and more targeted proposals using uGMRT (2019) and eRosita (2020).

Research Supervision

Ross has been an active supervisor of research students since 2015 on topics with a focus on theoretical astrophysics and computational Earth Sciences. These projects generally require a decent knowledge of programming in high-level languages such as python and some familiarity with lower-level languages including C++. A limited number of research projects may be available for prospective students wishing to study astrophysics in the fields of active galactic nuclei or cosmology. Students wishing to join the Computational Geophysics and Earth Informatics Group are encouraged to contact Professor Anya Reading to discuss potential projects.
