Astronomers have found rocky, earth-like exoplanets; now we need powerful spectrometers to search for biomarkers in their atmospheres, detecting the faint imprints from molecules associated with life in the colour spectrum of stars. This project will develop the instruments and technologies required to enable spectroscopy with massively multiplexed telescopes. A spectrometer design with large spectral bandwidth and high resolution, optimised for a facility consisting of thousands of small telescopes, and novel optical fibres to link them, will open the door for breakthrough science requiring an entirely new class of telescope.Read moreRead less

Planetary nebulae, the extended shrouds of dying stars, are a fascinating, brief period in the life of most stars. Our Sun will eventually go through this phase engulfing the earth. Planetary nebulae are unique celestial laboratories thanks to their rich emission line spectra. They are amongst the most beautiful and mysterious of objects, whose startling images act as a photogenic magnet for public interest. Behind their beauty hides the mystery of how stars return carbon, one of life's essential building blocks - to interstellar space. This project will constitute the next major breakthrough in understanding these processes and addresses several significant astrophysical problems in the field via unique Australian data and instrumentation.Read moreRead less

The powerful and sensitive CRACO system will also search for transients that last for hundreds of milliseconds, exploring new types of astrophysical phenomena that give insight into the Universe's extremes. These discoveries will have a significant impact on science, establishing Australia as a key player in the international FRB community.

This project aims to develop a robust, ultra-precise calibration system that improves the precision of Doppler spectrographs by a factor of ten –sufficient to discover rocky planets. The holy grail of exoplanet research is the discovery of an Earth-like planet in the habitable zone of a Sun-like star. The planet’s tug on its host star causes a periodic Doppler shift of the star’s spectrum which precision astronomical spectrographs record. Detecting minute shifts from rocky planets needs better precision than the best spectrographs provide. This project expects to help to discover Earth twins, habitable worlds outside the Solar system.Read moreRead less
Pinpointing the hosts of Fast Radio Bursts with UTMOST-2D. This project proposes to localise a sample of detected ‘fast radio bursts’ to their host galaxies (or local progenitors) for the first time. ‘Fast radio bursts’ are impulsive bursts of radio energy, with characteristics consistent with an origin billions of light-years from Earth. If the source of the bursts can be pinpointed, they would offer a unique tool to study the tenuous, otherwise nearly invisible plasma that permeates the interg ....Pinpointing the hosts of Fast Radio Bursts with UTMOST-2D. This project proposes to localise a sample of detected ‘fast radio bursts’ to their host galaxies (or local progenitors) for the first time. ‘Fast radio bursts’ are impulsive bursts of radio energy, with characteristics consistent with an origin billions of light-years from Earth. If the source of the bursts can be pinpointed, they would offer a unique tool to study the tenuous, otherwise nearly invisible plasma that permeates the intergalactic medium. They could also be used as cosmic rulers to measure the expansion history of the Universe. To date, no burst has been associated with a host galaxy at a known distance, and some researchers maintain that fast radio bursts originate from more nearby sources, potentially even within our own Galaxy. The project plans to explore this hypothesis.Read moreRead less

This project expects to localise 100s of bursts using novel infrastructure deployed on Australia's largest radio telescopes. Expected outcomes include an understanding of the processes that shape both the large-scale structures of the Universe, and the extreme conditions that exist at the sites of Fast Radio Bursts. This should provide significant benefits to our fundamental knowledge of the Universe, inspire students into careers in science, technology, engineering and mathematics, and develop signal processing techniques of application to both the Square Kilometre Array and industry.Read moreRead less

This project aims to improve spectrographic design in order to increase precision in astronomical research. The discovery of Earth's twin, a habitable world in another stellar system, is one of the most remarkable scientific endeavours of our time. The gravitational tug of the planet on its host star causes a periodic Doppler shift of the star’s spectrum which is recorded using spectrographs. The instrumental precision required to detect an Earth-like planet is a few centimetres per second, significantly better than the best current spectrographs can provide. This project plans to combine novel technologies from adaptive optics and astrophotonics into an innovative spectrograph design that will improve Doppler precision by a factor of ten, sufficient to find planets.Read moreRead less

This project aims to deploy a cryogenic camera system to improve the outputs of astronomical telescopes. The system is equipped with an emerging detector technology, a near-infrared Avalanche Photo-Diode array, capable of high cadence imaging with frame rates of 10 - 1,000 Hz at a wavelength of around 2.2 microns. This new technology is a key component to the future of adaptive optics systems for astronomical telescopes as it allows the rapid measurements necessary to correct the image blurring introduced by the Earth's atmosphere. No expertise currently exists in Australia with this new technology. Capitalising on previous investment, the camera system is intended to fill a capability gap in local expertise and to ensure the potential of the next generation of telescopes is realised and strengthen our competitive edge for frontier instrumentation across the wider Australian imaging community.Read moreRead less
