Formation of Supermassive Black Holes. One of the most remarkable discoveries in astronomy is the observation that supermassive black holes, weighing as much as a billion suns, are found in the centers of galaxies, including our own Milky Way. Astronomers do not understand how these black holes came to be, or their role in the evolution of galaxies. This Discovery Project will address these issues by analysing data on supermassive black holes from the local and early universes. Black holes fasci ....Formation of Supermassive Black Holes.

This Discovery Project will address these issues by analysing data on supermassive black holes from the local and early universes. Black holes fascinate students both young and old. This Discovery Project will train a new generation of young Australian astronomers at the leading edge of astrophysics.

Quantum enhancement of long baseline gravitational wave detectors. This project will design and construct a quantum optical system which when used in future long baseline gravitational wave detectors will enhance sensitivity across their detection frequency band, from 10 Hz to 10 kHz. This project will use this system on small scale optical sensors to prove the concept. In so doing, it will use squeezing to reduce quantum radiation pressure noise for the first time. This system will then be read ....Quantum enhancement of long baseline gravitational wave detectors. This project will design and construct a quantum optical system which when used in future long baseline gravitational wave detectors will enhance sensitivity across their detection frequency band, from 10 Hz to 10 kHz. This project will use this system on small scale optical sensors to prove the concept. In so doing, it will use squeezing to reduce quantum radiation pressure noise for the first time. This system will then be ready for deployment on an early upgrade of Advanced LIGO increasing the science output of this detector, turning gravitational wave detection into gravitational wave astronomy.Read moreRead less
“Beacons in the Night” unveiling how galaxies light up dark matter. 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 EA ....“Beacons in the Night” unveiling how galaxies light up dark matter. 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
Collaboration with The NANTEN2 International Star Formation Consortium. Through this collaboration Australia, for a very modest sum, will gain its first direct access to the astronomical facilities of the Atacama plateau, one of the best sites for investigating star formation on the Earth. The project fosters international collaboration, and raises the profile of Australian science and facilities by bringing together astronomers from Australia, Japan, Germany, Korea, Chile and Switzerland.The co ....Collaboration with The NANTEN2 International Star Formation Consortium.

Before Planets: The Mineralogy and Chemistry of Pre-Planetary Disks. Planets form within the circumstellar disks around young stars. Samples of the solid material composing our own primitive disk are found in meteorites and interplanetary dust particles. Using the powerful technique of astronomical mid-infrared spectropolarimetry, we will ascertain the composition of the material existing within the disks around young stars.

Planets form within the circumstellar disks around young stars. Samples of the solid material composing our own primitive disk are found in meteorites and interplanetary dust particles. Using the powerful technique of astronomical mid-infrared spectropolarimetry, we will ascertain the composition of the material existing within the disks around young stars. By studying a range of disk ages we will determine how the composition evolves with time, and what physical processes affect it, in order to better understand how our own solar system formed. Further, we will image these disks in mm-wave molecular emission and constrain their chemistry and rotational properties.Read moreRead less
Feeding the faintest black holes: the nature of low-luminosity accretion. The overwhelming majority of black holes are found in an extremely faint quiescent state. This project aims to improve understandings of this large population of black holes, determining the geometry of the inflowing gas, the source of the faint X-ray emission, and the fraction of energy pumped outwards in fast-moving jets. Building on recent ground-breaking results, this project aims to conduct a survey to detect a new po ....Feeding the faintest black holes: the nature of low-luminosity accretion. The overwhelming majority of black holes are found in an extremely faint quiescent state. This project aims to improve understandings of this large population of black holes, determining the geometry of the inflowing gas, the source of the faint X-ray emission, and the fraction of energy pumped outwards in fast-moving jets. Building on recent ground-breaking results, this project aims to conduct a survey to detect a new population of black holes in dense star clusters, providing new laboratories to explore accretion physics. It aims to measure the distances of the black holes and their motion through space, test evidence for the existence of event horizons, and provide new insights into how black holes form and how they affect their surroundings.Read moreRead less

Ever since their discovery Australia has played a prominent role in the discovery and monitoring of these enigmatic sources. The timing and discovery of millisecond pulsars is an area where Australia is a world leader. This programme will use a powerful new instrument on the Parkes radio telescope to search for the minute influence of gravitational waves from supermassive black hole binaries on the millisecond pulsars.Read moreRead less

Summary
Gas in the Cosmic Web: feeding and feedback of galaxies. This project aims to understand the complete cycle of gas in galaxies: from the process of feeding galaxies, going through star formation, to the process of outflowing gas from galaxies. This requires a full physical description of the inflow of gas from filaments going through the halo until reaching galaxies, the process of star formation in a multi-phase gas medium, and the effect energetic events have on the gas content of galaxies.

This project aims to understand the complete cycle of gas in galaxies: from the process of feeding galaxies, going through star formation, to the process of outflowing gas from galaxies. This requires a full physical description of the inflow of gas from filaments going through the halo until reaching galaxies, the process of star formation in a multi-phase gas medium, and the effect energetic events have on the gas content of galaxies. This project in the field of extragalactic astrophysics is designed to complement major observational efforts in Australia, such as the Square Kilometre Array and its Pathfinder, as it will provide simulations with full physical descriptions of the neutral gas in the Universe.Read moreRead less

The first direct detection of Einstein's gravitational waves from two merging black holes by the Laser Interferometer Gravitational Wave Observatory in 2015 began a new era of human discovery. This project is expected to progress gravitational wave science and Australia's role in it, and generate insights about the origin of neutron stars and the physics of bulk nuclear matter under extremes of gravity, density and magnetisation which cannot be replicated on Earth.Read moreRead less
