Joss Hawthorn, University of Sydney @jossblandhawthorn

Joss Bland-Hawthorn is an ARC Laureate Fellow Professor of Physics and Director of the Sydney Institute for Astronomy (SIFA). He was born in England before moving overseas in 1985. After receiving his PhD from the Royal Greenwich Observatory and the University of Sussex, he took a 3-year postdoc in astrophysics at the Institute for Astronomy, University of Hawaii. In 1988-1993, he was a tenured professor at the Space Physics & Astronomy Department, Rice University, Texas. In 1993, he joined the Australian Astronomical Observatory, Sydney. In 2000, he was appointed Head of Instrument Science, a new division that was created to reflect the increasing need for complex novel solutions to astronomical instrumentation.

In 2007, Joss was awarded the prestigious Federation Fellowship with a tenured professorship in the Sydney Institute for Astronomy (SIFA), School of Physics, University of Sydney. In 2009, he co-founded the Institute of Photonics and Optical Science (IPOS). In 2010, he was Leverhulme Professor at Oxford and held a Visiting Senior Fellowship at Merton College, Oxford. In 2011, he was the Brittingham Scholar at the University of Wisconsin, USA. He has won numerous awards including the Jackson Gwilt medal from the Royal Astronomical Society (2012) and the W.H. Steel medal from the Australian Optical Society (2015). In 2012, he was elected Fellow of the Australian Academy of Science and the Optical Society of America.

In 2014, Joss was awarded the Australian Laureate Fellowship. He serves on several boards including Section H (IAU) and the Annual Reviews of Astronomy and Astrophysics (USA). He has delivered... ...more...

Near field cosmology

You may wish to see a review I wrote with Ken Freeman on "The Baryon Halo of the Milky Way" (Science, Jan 2000) or a related article in "Clues to Galaxy Formation" (Nature, July 1999). Both of these articles attempt to show that the time is ripe for a general convergence of far-field cosmology and near-field cosmology (cosmogony). This is a topic Ken Freeman and I explore in our 2002 Annual Reviews article and in our 2007 Saas Fee lectures. An updated and extended version of these lectures was published in 2013; we provide download details below. ...more...

A new generation of astronomical instruments

SAIL has completed or is developing a range of novel astronomical instruments: SAMI, Hector, HERMES, GNOSIS, PRAXIS, MOHSIS, Pandora, Dragonfly, i-INSPIRE, PIMMS. SAMI is a major dark-time facility awarded 180 nights at the AAT to observe 3400 galaxies using integral field spectroscopy. This is to be extended to 100,000 galaxies with the automated Hector instrument in 2018. HERMES is a major bright-time facility at the AAT with the primary goal to observe a million stars using high-resolution spectroscopy over five years.

Astrophotonics and Space photonics

My interest in photonics started in 1999 when talking to Martin Harwit about the prospects of improved space communications. We were struck by how only a fraction of the potential data from space missions were getting back to Earth, even allowing for data compression. In 2002, I wrote two papers on "Laser Telemetry from Space" with father and son team, Martin & Alex Harwit (Science, July 2002). The papers were adopted as a NASA white paper in that same year and a workshop was held at JPL to discuss the work. My team at the AAO formed the Australian Centre for Space Photonics to pursue funding avenues. This led to a second NASA visit to Australia to attend the IAU 2003 where a special session was held on laser communications. In early 2006, and sooner than I had anticipated, a NASA Goddard team achieved the first interplanetary laser communications over a distance of 24 million km (Science, Jan 2006). With reference to our work, their paper describes how they used the MESSENGER satellite which is on a 6.6 year voyage to Mercury and due to arrive in early 2011. For more information, see our laser comms website. ...more...
