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

Jacinta Delhaize, speaking on "The VLA-COSMOS 3GHz Large Project: A new radio continuum survey for advancing galaxy evolution studies", to be held in the AAO Meeting Room (Room 7, 1st Floor, Building 2) at 11:00AM on Tuesday 29th August, 2017.
Abstract:
I will present the first suite of results, published in a recent special edition of Astronomy & Astrophysics, from the VLA-COSMOS 3GHz Large Project. This is a 400 hour radio continuum survey of the two-square-degree COSMOS field using the recently upgraded Very Large Array telescope. With nearly 11,000 radio sources detected, it is the most sensitive radio continuum survey currently available over a cosmologically-significant sky area. It also acts as one of the pathfinders for the upcoming ASKAP EMU survey, and for other large-scale continuum surveys with next-generation radio telescopes such as the SKA.

In combination with the plethora of superb multiwavelength data available in the COSMOS field, this is in an excellent resource for studies of galaxy evolution out to z~6. I will summarise some of the first key results. This includes a sophisticated method for decomposing radio source populations into star-forming galaxies and AGN, examining the redshift-dependent behaviour of the infrared-radio correlation of galaxies, and using the radio continuum as a dust-unbiased star formation rate tracer.
