Australia surveys the galaxies: The central role of environment

Australia's premier astronomical facilities will survey the galaxies in the coming decade, with the primary goal of understanding how galaxies (like the milky way) grow and evolve. Galaxies respond to the environments in which they reside. the Super Science Fellows will explore this connection, developing and using surveys with the Australian square kilometre array pathfinder and anglo-australian telescope. they will determine how hydrogen gas, the fuel for forming new stars, populates galaxies within the largest structures in the universe. the Super Science Fellows will determine when powerful active galactic nuclei prevent the formation of new stars within galaxies. this will lead to physically motivated models of galaxy evolution.
