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

Darshan Kakkad, speaking on "Title Unveiling the impact of AGN feedback using ALMA and SINFONI at z~1.5", to be held in the AAO Meeting Room (Room 7, 1st Floor, Building 2) at 11:00AM on Wednesday 5th October, 2016.
Abstract:
Galaxies at redshift 1-3 have become the prime focus of many observations. This is the peak epoch for both star formation and black hole growth in the cosmological history, and therefore it is an ideal laboratory to test the impact that AGN radiative feedback may have on their host galaxies. We will present two independent approaches to test AGN feedback: a) CO(2-1) observations from ALMA in a sample of “main sequence” AGNs to compare the star formation efficiency and gas fractions in active and inactive galaxies. b) SINFONI-IFU observations of a representative sample of high redshift quasars for which weobserve intermediate to high velocity kiloparsec-scale outflows using [OIII]5007 line diagnostics. We will discuss the constraints on the source of such detected outflows (AGN or star-formation) using simple outflows models. The combination of these SINFONI and ALMA observations allows us to test the impact of AGN feedback on both ionised and molecular gas content of their host galaxies.
