Prof. Bryan Gaensler

Patron of Macarthur Astronomical Society

Professor Bryan Gaensler is currently Director of the Dunlap Institute for Astronomy and Astrophysics, The University of Toronto (Canada) and was appointed as Patron of Macarthur Astronomical Society in November 2009. He is seen (above) addressing MAS members at UWS in November 2010.


Professor Gaensler was the 1999 Young Australian of the Year and gave the 2001 Australia Day Address to the Nation. He was born and raised in Sydney. He graduated from the University of Sydney in 1995 with First Class Honours in Physics. His final mark of 100%, the highest ever awarded in the Faculty of Science, saw him awarded the University Medal in Physics

As part of his PhD research in radio astronomy, he set out to understand why the remnants from exploding stars form particular patterns rather than just scatter off in random directions. He surprised the astronomical world by showing that these remnants all line up with the Galaxy's magnetic field like giant compasses. For this and other work, Bryan received his doctorate from The University of Sydney in 1999.


Professor Gaensler took up a Hubble Fellowship at the Massachusetts Institute of Technology (MIT) in Boston, was a Clay Fellow at the Smithsonian Institution and taught astronomy at Harvard University. As an Associate Professor at Harvard, he built the world's leading research group for studying neutron stars and supernova remnants.

Professor Gaensler returned to The University of Sydney as Professor of Physics in 2006 and is pictured above addressing the General Meeting of MAS  in May 2009: . His research group at Sydney focused it's work on the origin of magnetism in the Universe; and on the demography of neutron stars and black holes in our Milky Way.

He played a leading role in developing the Square Kilometre Array and in 2011 he became inaugural Director of the ARC Centre of Excellence for All-sky Astrophysics (CAASTRO), a post he held until 2014.

In 2010 Bryan won the Pawsey Medal for his pioneering studies of cosmic magnetism which have opened a new window on the Universe.


Bryan relocated to Canada in December 2014 to commence a five-year term as director of the Dunlap Institute for Astronomy and Astrophysics at The University of Toronto. He agreed to remain as Patron of Macarthur Astronomical Society.
