At cosmic noon, puffy galaxies make stars for longer

Galaxies with extended disks maintain productivity, research reveals

Massive galaxies with extra-large extended “puffy” disks produced stars for longer than their more compact cousins, new modelling reveals.

In a paper published in the Astrophysical Journal, researchers led by Dr Anshu Gupta and Associate Professor Kim-Vy Tran from Australia’s ARC Centre of Excellence in All Sky Astrophysics in 3 Dimensions (ASTRO 3D), show that the sheer size of a galaxy influences when it stops making new stars.

Background information on hot qubits and a timeline of Professor Dzurak’s work.

A proof-of-concept published today in Nature promises warmer, cheaper and more robust quantum computing. And it can be manufactured using conventional silicon chip foundries.

Most quantum computers being developed around the world will only work at fractions of a degree above absolute zero. That requires multi-million-dollar refrigeration and as soon as you plug them into conventional electronic circuits they’ll instantly overheat.

But now researchers led by Professor Andrew Dzurak at UNSW Sydney have addressed this problem.

Nobel laureate presents school science project

It’s not every day that school students get to present their science project to a major scientific conference, and rarer still to receive a prize for it from a Nobel Laureate.

That’s the happy experience today for a team of four Year 11 students from Gosford High School, who have won a national competition conducted by UNSW and the Australian Institute of Physics.

Accurate time with light and designing the NBN

Operations on 11 December, 2012

A new, cheaper way to deliver accurate time across Australia: instead of using hydrogen maser clocks costing hundreds of thousands of dollars we can bounce signals through the national’s optical fibre network according to physics leaders speaking today and tomorrow.

Also today at the national physics congress in Sydney, meet the man whose job it is to figure out how to build the NBN.

And hear about the magic of thermal plasmas, from safer arc welding to saving the ozone layer.

Can Australian researchers help maintain the technological superiority of the US Air Force?

Operations on 30 April, 2012

And what are the benefits for Australian research?

Today in Washington DC, the Australian Ambassador Kim Beazley will open a four day workshop with more than 60 US defence researchers and 33 Australian nanotechnology scientists.

The meeting, organised by the US Air Force Office of Scientific Research and the Australian National Fabrication Facility (ANFF), will explore opportunities for collaboration in nanotechnology and nano-manufacturing.
