astronomer Sydney van den Bergh predicted a decade ago that "The
astronomy of the 21st century will be dominated by computer-based
manipulation of huge homogeneous surveys of various types of
astronomical objects." In many ways this has come true, and
I hope to share with you some of the excitement of the large,
wide-field astronomical surveys in which I and my colleagues have been
involved. I will talk about some of the challenges of this kind
of work, as well as showing how wide-field astronomy can provide unique
insights into the evolution of galaxies and their central black holes
over timescales of billions of years. Finally, I will give a
glimpse of future developments in wide-field radio astronomy.
Elaine Sadler completed an undergraduate physics
degree at the University of Queensland, followed by a PhD in astronomy
from the Australian National University. She held postdoctoral
fellowships at the European Southern Observatory in Germany and Kitt
Peak National Observatory in the United States before returning to
Australia in 1988 to take up a research position at the
One of her main research interests is galaxy evolution, using large observational data sets to study how galaxies form and change on timescales of billions of years.
Elaine is currently an ARC Australian Professorial Fellow in the School of Physics at the University of Sydney. She is also president of Division VIII (galaxies and the universe) of the International Astronomical Union, and chair of the National Committee for Astronomy.
