He is the Project Scientist and founder of the Sydney Astrophotonic Instrumentation Lab (SAIL) and the Director of the Sydney Institute for Astronomy, both at the University of Sydney.[22][23] He was elected an International Honorary Member of the American Academy of Arts and Sciences in 2023.[24] Bland-Hawthorn sits on several boards, including: Astronomy Australia Limited, The Australis Board, and the Annual Review of Astronomy and Astrophysics.[15]
Researchedit
Bland-Hawthorn first coined the term "near-field cosmology," which looks at the early physical histories of stars and galaxies, in his Nature article Clues to galaxy formation and in 2002 co-wrote an Annual Review article with Ken Freeman giving a more detailed description of this topic.[25][26][27][28] The Annual Review paper additionally introduces galactic archaeology, chemical tagging, and the use of high spectroscopic resolution to conduct mass star surveys.[25][29][30][9] This technology has been in use since 1993 and still plays a large part in surveys such as the APO Galactic Evolution Experiment (APOGEE), the Radial Velocity Experiment (RAVE), Gaia-ESO (GES), Large Sky Area Multi-Object Fibre Spectroscopic Telescope (LAMOST), the William Herschel Telescope Enhanced Area Velocity Explorer (WEAVE), and 4MOST, as well as the Galactic Archaeology with HERMES (GALAH) with which he is involved.[31][32][33][34][35][36] In 2011, Bland-Hawthorn, Sanjib Sharma, Kathryn Johnston, and James Binney developed Galaxia, a galaxy model simulation code.[37] In 2016, he and Ortwin Gerhard were able to identify properties of the Milky Way that could act as a fossil record.[38][39][40]
Bland-Hawthorn is particularly interested in the Milky Way.[41] In 2003, he and Martin Cohen wrote about the galaxy's bipolar x-ray wind, which they spotted using the ROSAT satellite; this theory was not proven until 2010.[42][43] Bland-Hawthorn continues to write about simulated galactic winds[44] and Smith's Cloud.[45] He wrote several articles showing that high-velocity HI clouds are within the Galactic halo rather than at megaparsec distances as originally thought.[46][47][48] He was also the first to show that the HI disc in the outer parts of spiral galaxies undergoes a phase change and becomes ionized.[49]
In 2000, he established the field of astrophotonics.[citation needed] Among the many technologies and instruments he has worked on and developed over his career are the photonic lantern, OH-suppression fibres, hexabundles, and the photonic integrated multimode microspectrograph; all of these also have applications in other fields.[50][51][52][53] Bland-Hawthorn's experimental work in 2021 focuses on exploratory use of quantum technologies in the field of astronomy.[54][55][56] He and colleagues John Bartholomew and Matt Sellars proposed that quantum memories at different telescopes can be combined to perform very-long-baseline interferometry at infrared wavelengths.[54]
Bland-Hawthorn has more than 1,000 publications and has been cited upwards of 65,000 times according to ResearchGate.[57]
