2017 Colloquia

Friday Mar 24, 10:30
Tyler Bourke (SKA)
Colloquium: The Square Kilometre Array - Science and Status Update
The Square Kilometre Array (SKA) will be the world's largest radio telescope when Phase 1 is completed in the next decade. The past few years have seen great progress toward this goal, with construction to start in 2019 and science operations anticipated to begin in 2024. In this presentation I will provide a status update on SKA activities, with a focus on the science it will enable.

Caroline Foster (AAO)
Colloquium: The true shape of galaxies
The intrinsic or true three-dimensional shape of galaxies is one of their most fundamental characteristic. Yet, due to projection effects, the true shape of galaxies is a difficult property to measure accurately. The most reliable method for inferring intrinsic shapes require large samples of spatially resolved stellar kinematic maps. Large IFU surveys are now enabling this type of science to be done accurately on carefully selected samples of galaxies. I am using the SAMI Galaxy Survey to uncover the intrinsic shape of various carefully selected galaxy samples. Preliminary results will be presented.

Steven Janowiecki (University of Western Australia)
Colloquium: Gas and star formation in galaxies: the role of environment and (almost) dark galaxies
I will talk about recent work studying gas and star-formation in samples of galaxies. In particular, using the new xGASS survey, we have found unusually gas-rich and star-forming central galaxies in small groups, which we interpret as evidence of feeding from the cosmic web. At the other extreme, the ALFALFA HI survey is finding gas-rich galaxies with almost invisible stellar populations. These (almost) dark galaxies are exceptionally inefficient at forming stars and may be related to the recently re-discovered class of "ultra-diffuse" galaxies.

Tara Murphy (University of Sydney)
Colloquium: Making the leap: from academic to start-up founder
My research is in radio astronomy, in particular in the dynamic radio sky, using intelligent algorithms to find rare objects in large datasets. In 2013, along with a colleague and two PhD students I took a leap into the unknown and started a company "Grok Learning" that provides online computing education for school students, teachers and universities. We now have thousands of users from around the world, and a team of 10 staff including the founders.
In this talk I'll discuss how our academic training (as astronomers and computer scientists) was helpful in the business world, but also the challenges you might face. How does running your own business compare to a job in academia? What astronomy skills are useful in the business world? What should you do if you're interested in starting a business?
I'm happy to leave plenty of time for discussion, so bring your questions!

Tanya Hill (Melbourne Planetarium, Scienceworks)
Colloquium: Melbourne Planetarium - tapping into the public appeal of astronomy
Astronomers well recognise the appeal of their subject among the wider public. Astronomy has beautiful, eye-catching imagery, its discoveries are attention grabbing and evoke the world of science fiction, and at its most basic level, everyone has the potential to explore and be captivated by the night sky. Our understanding of the universe has changed greatly since the world's first demonstration of a planetarium projector in Munich, Germany, 1923. Here's my review of how Melbourne has continued to tap into the public's curiosity for astronomy and evolved with the times to keep the public informed about the universe we live in.
