Ancient stars: the origin of elements. The story of the origin of the elements fascinates mankind and touches many branches of science. This project combines new stellar population models of the oldest stars with new data from the Australian million-star GALactic Archaeology with HERMES (GALAH) survey to address basic astrophysical problems: mixing in stars, mass transfer in binary stars and measurement of the masses of the first stars. Knowing how these ancient stars behave is crucial to unders ....Ancient stars: the origin of elements. The story of the origin of the elements fascinates mankind and touches many branches of science. This project combines new stellar population models of the oldest stars with new data from the Australian million-star GALactic Archaeology with HERMES (GALAH) survey to address basic astrophysical problems: mixing in stars, mass transfer in binary stars and measurement of the masses of the first stars. Knowing how these ancient stars behave is crucial to understanding element production in the early Universe, both in our Milky Way and distant galaxies. By statistically comparing new models to the GALAH data, this project aims to measure the masses of the oldest galactic stars directly impacting branches of astrophysics from planets to galaxies.Read moreRead less
Gravitational-wave astronomy: detection and beyond. This project aims to detect ripples in the fabric of spacetime known as gravitational waves by using new data analysis techniques while developing technology to enable the next generation of gravitational-wave detectors. Detection of gravitational waves would constitute a revolution in astronomy, allowing us to probe the most dramatic events in the Universe with a new form of radiation. During the next five years, it is probable that gravitatio ....Gravitational-wave astronomy: detection and beyond. This project aims to detect ripples in the fabric of spacetime known as gravitational waves by using new data analysis techniques while developing technology to enable the next generation of gravitational-wave detectors. Detection of gravitational waves would constitute a revolution in astronomy, allowing us to probe the most dramatic events in the Universe with a new form of radiation. During the next five years, it is probable that gravitational waves will be detected. Terrestrial detectors, operating in the audio band, and pulsar timing arrays, operating in the nanohertz band, are both rapidly approaching the required sensitivity. This project is designed to make important contributions to gravitational-wave astronomy at a crucial time.Read moreRead less
