Stanislav.Shabala@utas.edu.au

Stas Shabala is a Lecturer in Physics and ARC Early Career Fellow at the University of Tasmania. His primary area of research is extragalactic astrophysics, with a focus on the formation and evolution of galaxies, and the physics of active supermassive black holes (Active Galactic Nuclei; AGN). He is particularly interested in developing the theoretical tools required for interpretation of next-generation large sky surveys, including by the Square Kilometre Array and its pathfinders. Stas also develops new observing and analysis techniques for geodetic and astrometric Very Long Baseline Interferometry, including detailed consideration of AGN physics. Stas is passionate about science participation and outreach. He is the current Chair of the Tasmanian Branch of the Australian Institute of Physics, and the project manager of the Radio Galaxy Zoo citizen science project.

Biography

Stas completed a PhD in astrophysics and cosmology at the University of Cambridge in 2008. He held an Astro Junior Research Fellowship at Oxford University and New College (2008-2010), before returning to Tasmania to commence an ARC Super Science Fellowship in early 2011. Most recently he has held an ARC DECRA Fellowship (2013-2016). 

Stas has authored more than 30 peer-reviewed publications in astronomy and geodesy, and has won over $1M in research funding, including >$0.5 M as a first-named investigator.   His current research interests are at the interface of astrophysics and geodesy. Stas is particularly interested in: (i) the co-evolution of supermassive black holes and their host galaxies; (ii) the physics of Active Galactic Nuclei, particularly at radio wavelengths; (iii) theoretical models required for interpretation of large astronomical radio surveys; (iv) the effects of AGN structure and evolution in astrometric and geodetic VLBI measurements; (v) development of new VLBI observing and analysis strategies.

Research Themes

Stas's main research interests are concerned with Active Galactic Nuclei, galaxy evolution, astrometry and space geodesy. In astronomy, he is primarily interested in the formation and evolution of galaxies. A major focus of his research is the interaction between galaxies and supermassive black holes (or Active Galactic Nuclei, abbreviated to AGN). He studies both how AGN regulate the star formation history and gas content of the Universe, and also the reverse: how the processes that shape galaxies affect AGN activity. To address these questions, Stas develops analytical and numerical models that capture AGN physics, in particular the dynamics and synchrotron emission from plasma jets ejected by the black hole accretion disk. He also uses radio and optical observations from a number of Australian and overseas telescopes.

In geodesy and astrometry, Active Galactic Nuclei essentially serve as beacons that can be used to measure positions on Earth and the orientation of Earth is space. The Very Large Baseline Interferometry (VLBI) technique used for these measurements is incredibly accurate: distances between radio telescopes separated by thousands of kilometres (for example, in Tasmania and Hawaii) can be routinely measured to within a couple of centimetres! Even this might not be good enough for some geophysical and environmental questions, however. To achieve even higher accuracy, AGN physics as well as other effects such as antenna deformation and light distortion by the Earth's atmosphere must be understood. Stas develops geodetic simulations, observing strategies and analysis techniques that incorporate the physics of AGN jets. Yes, you read that right – Stas uses black hole physics to improve the accuracy with which we can measure Earth-based processes.

Eternal struggle: star formation and black hole activity in galaxies (2013 - 2015)$370,799
Description
Star formation and black hole activity in galaxies are triggered by similar processes, and are tightly coupled throughout cosmic history. Despite this, they affect galaxies in very different, often competing ways. Thus, understanding of the processes governing the onset of star formation and black hole activity, and their interaction, are central to our comprehension of galaxy formation. This project will study the link between these processes by combining state-of-the-art models with observations of galaxies with the youngest, most compact active black holes. The project will shed light on fundamental processes governing the formation and evolution of galaxies throughout cosmic time.

Research Supervision

Please get in touch with Stas if you are interested in a PhD in astrophysics or geodesy, particularly relating to the physics of galaxies and / or Active Galactic Nuclei. Available projects span a broad range of science and techniques, including analytical modelling, numerical simulations, statistical analysis of large data sets, and hands-on observations using our very own AuScope VLBI array. Prospective candidates are expected to have a strong track record (1stclass Honours for Australian / New Zealand applicants; Masters or equivalent plus good English for overseas candidates).
