Prof Brough is leading Australia into a new astronomical survey of the southern sky, recently securing ARC LIEF funding for 235 Australian astronomers to access the Vera C. Rubin Observatory's Legacy Survey of Space and Time (LSST). She has been a key member of three major Australian-led surveys of galaxies, and has published over 240 research papers examining how galaxies have changed over time. Prof Brough is particularly interested in the most massive galaxies in the Universe, which represent the most extreme result of galaxy formation. LSST will open up novel avenues of investigation across all astronomical research areas, including very faint signatures of galaxy formation. Prof Brough leads an LSST working group on this subject.
