Relativistic jets and radio-mode feedback in massive galaxies

Australia is a world leader in the development of new technologies for radio astronomy. We will use a new wide-band correlator on the Australia Telescope to map the high-frequency radio sky with unprecedented speed and sensitivity. This allows us to detect and measure the radio emission from black holes at the centre of massive galaxies. Our aim is to test current theories of galaxy formation and improve our understanding of the symbiotic relationship between a galaxy and its central black hole. Our work will provide a powerful complement to existing and future low-frequency radio surveys, and will pave the way for future exploration of the high-frequency radio Universe with the Square Kilometre Array.
