The fossil record of galaxy formation. This Australian-led team recently used the Anglo-Australian Telescope to discover large numbers of a new type of very small galaxy in the centres of two galaxy clusters. This project will maintain Australian leadership in this new area of astrophysics research, whilst using the best international expertise and facilities.
The formation and structure of distant galaxies. (i) The proposed galaxy evolution science involves the study of one of the most fundamental processes within the universe, thereby contributing to the Priority Goal of 'Breakthrough Science' under National Research Priority 3. (ii) It will bring national benefit through international collaborations with prestigious US, UK, and Canadian institutions. (iii) These collaborations will lead to new research capacity being built within Australia, with co ....The formation and structure of distant galaxies.

(ii) It will bring national benefit through international collaborations with prestigious US, UK, and Canadian institutions. (iii) These collaborations will lead to new research capacity being built within Australia, with considerable knowledge and expertise being vested in young postgraduate and postdoctoral researchers.Read moreRead less
Galaxy recycling in clusters of galaxies. Large galaxies are thought to form by merging smaller dwarf galaxies, but recent discoveries reveal a more violent picture: some dwarf galaxies are torn apart by the gravity of their companions, their contents strewn across inter-galactic space.
We will investigate how much this debris is recycled into other galaxies. We will examine Hubble Space Telescope images of dwarf galaxies to test if they are broken up to form the ultra-compact dwarf galaxies we ....Galaxy recycling in clusters of galaxies.

We will investigate how much this debris is recycled into other galaxies. We will examine Hubble Space Telescope images of dwarf galaxies to test if they are broken up to form the ultra-compact dwarf galaxies we recently discovered. We will model the rate at which dwarf galaxies are disrupted to determine how the dark matter is distributed in such galaxies.Read moreRead less
