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

Ho Seong Hwang, speaking on "Mapping the Distribution of Galaxies at Intermediate Redshifts: Galaxy Clusters and Large-scale Structure of the Universe", to be held in the AAO Large Meeting Room (Room 1, Ground Floor, Building 3) at 11:00AM on Thursday 28th July, 2016.
Abstract:
Measurement of the matter distribution in the universe is one of the key components in observational cosmology. This provides an important test of structure formation scenarios and cosmological models. I discuss two aspects of this test: (1) comparing the matter distribution around galaxy clusters from galaxy redshift surveys with that from weak-lensing surveys and (2) statistical comparison of large-scale structure between observations and cosmological simulations. These tests underscore the importance of mapping the large-scale structure of the universe for exploring and understanding cosmology and structure formation. I emphasize the power of combining observations including redshift and weak-lensing surveys with cosmological simulations.
