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.


Because they are so bright, the black hole jets are visible across most of the Universe to radio telescopes. The Square Kilometre Array will discover tens of millions of jets, in their active ("on") and remnant (recently "switched off") phases. The aim of this PhD project is to construct a theoretical framework to interpret these data.


This project will use analytical modelling and highly parallel High Performance Computing (HPC) magnetohydrodynamic (MHD) numerical simulations of relativistic jets, to predict detailed radio synchrotron emission of these jets as they interact with the dynamic surrounding gas, throughout the jet lifecycle. Comparison of model predictions with data from SKA pathfinders will constrain the mechanisms responsible for the switching on and off of black hole jets.
This project will be performed in collaboration with colleagues from the University of Hertfordshire, International Centre for Radio Astronomy Research (ICRAR), the Netherlands Institute for Radio Astronomy (ASTRON), and CSIRO.
