AAO Colloquia

The AAO organises frequent colloquia at our North Ryde headquarters. These are usually held Thursday morning at 11:00 am, though other dates are occasionally scheduled. We welcome talks from visiting astronomers - if you are passing through Sydney and would like to tell us about your work, please fill out the AAO Visitor Form. The ATNF (Australia Telescope National Facility) also organises colloquia at their Epping offices. A schedule for these talks can be found on the ATNF Colloquia webpage. The AAO and ATNF occasionally organise Joint Colloquia when the speaker is likely to be of interest to both radio and optical communities. These talks will be found in both the list below, and the ATNF schedule. A list of past speakers can also be found below.

Samuel Nathan Richards, speaking on "Advancements in multi-object integral-field spectroscopy | PhD exit talk", to be held in the AAO Meeting Room (Room 7, 1st Floor, Building 2) at 03:00PM on Wednesday 25th May, 2016.
Abstract:
The Sydney-AAO Multi-object Integral-field spectrograph (SAMI) on the 3.9m Anglo-Australian Telescope has pioneered a new mode of observing galaxies that obtains spatially resolved spectroscopy on a dozen galaxies in one snapshot. Over 1500 galaxies have observed to date, with the survey still underway. These data have been used to test the assumptions in the popular Hopkins et al. 2003 and Brinchmann et al. 2004 aperture corrections (GAMA and SDSS respectively), that reveal significant biases in star formation rates dependant one’s target selection. A clear example of this is presented in the discovery of an off-centred star forming region in the dwarf galaxy GAMA 567676 that contributes ~70% of the galaxy’s total star formation rate, and is ~0.2 dex lower in metallicity compared with the rest of the galaxy. SAMI’s success has been built on technological developments. One of these developments is the introduction of polymer imaging fibre bundles (PIBs) as multi-object field acquisition and guide probes. These PIBs have the ability to transmit a spatially coherent image short lengths (
