Sydney Institute for Astronomy (SIfA)

The Sydney Institute for Astronomy (SIfA) is a national and international leader in Astronomy and Physics, through cutting edge theoretical and observational research and the application of new technology for the next generation of instruments and telescopes. As well as being a research leader, SIfA is committed to excellence in postgraduate training and research-led undergraduate training.

SIfA astronomers obtain observational data from major facilities in Australia, overseas, and in space. We also operate our own radio telescope, the Square Kilometre Array Molonglo Prototype (SKAMP), while the Sydney University Stellar Interferometer (SUSI) is the major element in our broad program of high resolution optical imaging. We also frequently receive observing time on the national facilities in Australia - the Anglo-Australian Telescope (AAT - optical) and the Australia Telescope National Facility (ATNF - radio).

SIfA is also the home of CAASTRO - the ARC Centre of Excellence for All-sky Astrophysics.

What do we do?

SIfA scientists conduct research in many exciting frontline areas including stellar astrophysics, plasma astrophysics, cataclysmic variables, black-hole binaries, masers, pulsars, supernovae and their remnants, the interstellar medium and the Galactic Centre. Beyond our Galaxy, we study normal galaxies, the Magellanic Clouds, clusters of galaxies, active galaxies & quasars, gravitational lensing and cosmology. Find out more about SIfA's exciting work on our Research and Surveys pages.

SIfA builds on a long tradition of astrophysical research at The University of Sydney, as described on our page on SIfA history.

Where is SIfA?

SIfA staff and students can be found at 44 Rosehill Street, Redfern (see map).

What's new at SIfA?

The SIfA Director, Professor Joss Bland-Hawthorn, has recently been awarded an Australian Research Council (ARC) Laureate Fellowship that includes funding for 6 Postdoctoral Fellowships (3-5 yrs) and 6 PhD scholarships over the next two years. We are particularly interested in the following science fields:

  • near-field cosmology & galactic archaeology (GALAH, RAVE, Kepler, Gaia surveys)
  • The Local Group, chemical evolution, first stars and dwarf galaxies
  • galaxy evolution, accretion and feedback (SAMI, GAMA, ASKAP surveys)
  • next-generation astronomical instrumentation (astrophotonics)
  • software development (advanced linear programming, statistical methods)

Expressions of interest should be sent to .
