How dark matter influences the formation and evolution of galaxies is to this day an outstanding question in astrophysics. To answer it, world-class facilities and a unique combination of observations and theory are required. This DP team, a world-class team of observers and theorists, will tackle this question by leveraging on two multi-million dollar projects: the MAGPI galaxy survey and the hydrodynamical simulations suite EAGLE-XL. MAGPI will deliver exquisite kinematics for hundreds of galaxies in the middle ages of the Universe, providing a view to the effect of dark matter on galaxies at this critical time, while EAGLE-XL represents the technological frontier in simulations and provides the best interpretative framework for MAGPI.Read moreRead less
Building galaxies in our backyard: satellites and stellar streams in the Local Group. By finding and studying faint satellites and stellar streams in the Local Group, this project will address basic questions about the formation and evolution of galaxies like our Milky Way. The project will also probe the conditions of star formation in the early universe, and the properties of the dark matter which constitutes most of the mass in our universe.
The evolution of mass and energy over the past 13 billion years. The universe has slowly transformed atomic material into a range of structures from planets, stars, galaxies, clusters and filaments. In the process the universe has generated energy at almost all wavelengths. This project will build a model to explain the evolution of mass, energy and structure in the universe and will test the model using the latest data.

Summary
How galaxies lose their gas: jet-driven outflows in the distant universe. This project aims to make measurements of the impact that powerful radio jets, launched from supermassive black holes at the heart of galaxies, have on their host galaxy. Understanding how galaxies evolve remains a key unanswered question in astronomy. The project will map the interaction between radio jets and the cold gas in galaxies to further distances than ever before, shedding light on how jets impact their environme ....How galaxies lose their gas: jet-driven outflows in the distant universe. This project aims to make measurements of the impact that powerful radio jets, launched from supermassive black holes at the heart of galaxies, have on their host galaxy. Understanding how galaxies evolve remains a key unanswered question in astronomy. The project will map the interaction between radio jets and the cold gas in galaxies to further distances than ever before, shedding light on how jets impact their environment at a crucial point in the lifecycle of radio galaxies. These results will challenge our understanding of how galaxies have evolved over the past 8 billion years and provide a much-needed observational basis to inform future simulations of galaxy evolution.Read moreRead less
The Taipan Survey - Cosmology in the Nearby Universe. This project aims to support the Taipan (Transforming Astronomical Imaging-surveys through Polychromatic Analysis of Nebulae) survey, which is designed to measure redshifts for 500 000 galaxies and peculiar velocities for 50 000 galaxies in the nearby universe. The survey aims to yield the most precise direct measurement of the present-day expansion rate of the universe, the largest maps of the density and velocity fields of local structures, ....The Taipan Survey - Cosmology in the Nearby Universe. This project aims to support the Taipan (Transforming Astronomical Imaging-surveys through Polychromatic Analysis of Nebulae) survey, which is designed to measure redshifts for 500 000 galaxies and peculiar velocities for 50 000 galaxies in the nearby universe. The survey aims to yield the most precise direct measurement of the present-day expansion rate of the universe, the largest maps of the density and velocity fields of local structures, and new and stringent tests of large-scale gravitational physics using galaxy motions, probing Einstein’s theory of gravity and alternatives. It is expected that the Taipan database will add substantial value to research with the SkyMapper telescope and the Australian SKA Pathfinder. The project also aims to demonstrate an innovative Australian robotic technology ('starbugs') that will be used in the next-generation Giant Magellan Telescope.Read moreRead less
Low mass galaxies and the growth of galaxy halos. This project aims to understand the evolutionary processes that shape low-mass galaxies and test current theories for the growth of galaxy halos from the continued accretion of low mass galaxies. Using new instrumentation on the world's largest telescope, the project intends to conduct the first survey to directly link galaxy halos with their expected origin. The project plans to compare the properties of low-mass galaxies with the substructures ....Low mass galaxies and the growth of galaxy halos. This project aims to understand the evolutionary processes that shape low-mass galaxies and test current theories for the growth of galaxy halos from the continued accretion of low mass galaxies. Using new instrumentation on the world's largest telescope, the project intends to conduct the first survey to directly link galaxy halos with their expected origin. The project plans to compare the properties of low-mass galaxies with the substructures seen in galaxy halos, which are predicted to arise from such low-mass galaxies.Read moreRead less
Cosmic origins: How do galaxies build chemical complexity over cosmic time? This project aims to answer questions of how the chemical complexity required to form stars, planets and life arose through cosmic history. Galaxies are the chemical factories of the Universe. Over the life of the cosmos, they have built reservoirs of the elements required to make stars and planets. Yet we have no complete theory of how this process unfolds or how different galaxy types form. By using advanced instrument ....Cosmic origins: How do galaxies build chemical complexity over cosmic time? This project aims to answer questions of how the chemical complexity required to form stars, planets and life arose through cosmic history. Galaxies are the chemical factories of the Universe. Over the life of the cosmos, they have built reservoirs of the elements required to make stars and planets. Yet we have no complete theory of how this process unfolds or how different galaxy types form. By using advanced instrumentation and developing innovative computational techniques, this project aims to use the motions and chemistry of stars to map the history of galaxies in a new way. This would establish where and when stars formed in different galaxies, revealing the importance of black holes, dark matter, galaxy collisions and local environment in the build-up of chemical complexity in our Universe.Read moreRead less
The birth and rebirth of radio galaxies. When gas falls onto a massive black hole at the centre of a galaxy, it can generate powerful radio emitting jets. By using radio telescopes to make new multi-frequency observations of distant galaxies, the project will map out these accretion events and measure how the birth rate of radio galaxies changes with cosmic time and environment.
The impact of impact: what stops star formation in cluster galaxies? This project aims to explain the fundamental differences observed in the star forming properties of galaxies in high and low density environments. This will be achieved by using innovative technology to observe the spatially resolved star forming properties of galaxies in clusters of galaxies, the densest and most extreme environments. These observations will be coupled with a new method for defining galaxy environments, which ....The impact of impact: what stops star formation in cluster galaxies? This project aims to explain the fundamental differences observed in the star forming properties of galaxies in high and low density environments. This will be achieved by using innovative technology to observe the spatially resolved star forming properties of galaxies in clusters of galaxies, the densest and most extreme environments. These observations will be coupled with a new method for defining galaxy environments, which is based on physical properties. The combination of these techniques will be used to establish the degree to which the physical mechanisms acting in clusters impact the star forming properties of infalling galaxies. This will significantly advance understandings of the impact of environment on galaxy evolution.Read moreRead less
