About the research project
Accretion of matter onto supermassive black holes at the centres of galaxies releases the most energetic outbursts in the Universe. Resultant jets of synchrotron-emitting plasma, visible to radio telescopes, burrow through the surrounding gas in the host galaxy and larger-scale galaxy cluster. This gas is the raw fuel from which stars are made, and by imparting some of their energy to it the black hole jets are known to regulate the star formation history of the most massive galaxies.
Much is unknown about the processes responsible for triggering and propagation of black hole jets. On the other hand, current and upcoming surveys with leading international telescopes (Square Kilometre Array pathfinder instruments, including ASKAP and MWA in Australia – and eventually the SKA itself) will study these objects in unprecedented detail across a wide range of radio frequencies. The aim of this project is to construct an equally sophisticated theoretical framework to interpret these data.
This project will use highly parallel High Performance Computing (HPC) magnetohydrodynamic (MHD) numerical simulations of relativistic jets, together with a state-of-the-art model for calculating the resultant synchrotron emission, to predict detailed radio synchrotron emission and polarization signatures of these jets as they interact with the surrounding galactic and intergalactic gas. Comparison of simulation predictions with data from SKA pathfinders will constrain the mechanisms responsible for the onset and cessation of jet activity, and help to guide development of future observing strategies.
This project will be performed in collaboration with colleagues from the University of Hertfordshire, International Centre for Radio Astronomy Research (ICRAR), CSIRO, and the Netherlands Institute for Radio Astronomy (ASTRON).
