Ordinary Meeting - 'Large Scale Galactic Surveys'

Friday 14th June 2013 - 8:00pm
Topic:  Large Scale Galaxy Surveys
Speaker:  Dr James Allan, University of Sydney
Venue: Epping Creative Centre - 26 Stanley Road, EppingAbstract: In recent decades, technological advances have allowed telescopes to be fitted with more and more sensitive instruments, allowing observations of large numbers of faint objects. Simultaneously, computing power and storage capacity has increased exponentially. Taken together, these advances have allowed astronomical surveys to expand massively in size and scope. Modern surveys can produce terabytes of data every night, and some run uninterrupted for many years. I will introduce a number of surveys - past, present and future - that have had, or will have, major impacts on our understanding of the universe. The main focus will be on optical (visible-light) surveys that study galaxies in order to understand how they have evolved over the history of the universe. In particular, I'll describe my own work using SAMI, the Sydney-AAO Multi-object Integral field spectrograph, which allows detailed studies of the internal structure of an unprecedented number of galaxies.
Biography: James grew up in England and studied at the Institute of Astronomy in the University of Cambridge. In 2011, after completing his PhD, he moved to Australia to work at the University of Sydney as a Super Science Fellow.
