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.

Next Scheduled AAO Colloquium

Luca Casagrande, speaking on "Investigating the age structure of the Milky Way disc", to be held in the AAO Meeting Room (Room 7, 1st Floor, Building 2) at 11:00AM on Thursday 19th January, 2017.
Abstract:
Setting the timeline of the events which shaped the Milky Way disc through its 13 billion year old history is one of the major challenges in the theory of galaxy formation. It is possible to achieve this goal using late-type stars, which in virtue of their long lifetimes can be regarded as fossil remnants from various epochs of the formation of the Galaxy. I present recent attempts in this direction, using both seismic and isochrone ages, and discuss how the age distribution of stars suggests a mostly quiescent evolution for the Milky Way disc since a redshift of about two. I stress the importance of dealing with survey selection functions, and target selection effects to derive unbiased inferences in stellar population studies, and show how photometric surveys can help in such a quest.
