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

Dr. T. J. Brandt, speaking on "Galactic Cosmic Rays: From Earth to Sources", to be held in the AAO Meeting Room (Room 7, 1st Floor, Building 2) at 11:00AM on Wednesday 10th February, 2016.
Abstract:
For over 100 years we have known that cosmic rays come from outer space,yet proof of their origin, as well as a comprehensive understanding oftheir acceleration, remains elusive. Direct detection of high energy(up to 10^15eV), charged nuclei with experiments such as the balloon-born,antarctic Trans-Iron Galactic Element Recorder (TIGER) and the recentlyflown SuperTIGER have provided insight into these mysteries throughmeasurements of cosmic ray abundances. The abundance of rare heavy elementswith respect to certain intrinsic properties suggests that cosmic rays includea component of massive star ejecta.Supernovae and their remnants (SNe & SNRs), often occurring at the end of amassive star's life or in an environment including massive star material,are one of the most likely candidates for sourcesaccelerating galactic comic ray nuclei up to the requisite high energies.The Fermi Gamma-ray Space Telescope Large Area Detector (Fermi LAT) hasimproved our understanding of such sources by widening the window ofobservable energies and thus our view into potential sources' energeticprocesses. Since Fermi LAT surveys the whole sky, we have created the firstsystematic study of GeV emission in all regions containing known SNRs. Notonly does this catalog, in combination with the wealth of multiwavelengthdata available, allow us to constrain SNRs' ability to accelerate cosmicrays, but it also provides statistically-motivated insight into the innerworkings of GeV-emitting SNRs.
