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

Phillip Lah, speaking on "The Cosmic Evolution of Neutral Atomic Hydrogen Gas", to be held in the AAO Meeting Room (Room 7, 1st Floor, Building 2) at 11:00AM on Thursday 5th March, 2015.
Abstract:
In order to understand the evolution of star formation in galaxies one needs to understand the evolution of neutral atomic hydrogen gas (HI), an important supply of fuel for star formation.

In this talk I will outline how neutral atomic hydrogen gas can be measured at a variety of redshifts and present the current status of measurements of the cosmic neutral atomic hydrogen gas density. I will also examine how the neutral atomic hydrogen gas density may vary in different density environments in a way different from the overall cosmic density pattern.

Finally I will discuss the likely effect on this area of science of current and future radio telescopes along with future planed surveys.
