We steered a laser beam through atmospheric turbulence to show how this technology could benefit fundamental science and spacecraft communications. Light can carry a lot more information than radio waves can. The bandwidth (data rate) of a transmission is limited by the frequency of that transmission. This is the main difference between 4G and 5G … Continue reading Shake it off: taking the twinkle out of a laser beam

With thousands of radio dishes spread over thousands of kilometres, the Square Kilometre Array will be the largest and most powerful radio telescope in the world and able to explore the deepest regions of the cosmos. But only if these thousands of radio dishes, some hundreds of kilometres apart, can be synchronized to within a … Continue reading Getting in Sync with the SKA
There is an old adage in the performing arts that you should never work with animals or children, though as a rule of thumb it seems to apply equally well to just about any profession. As an experimental physicist, I thought I had managed to steer clear of the troubles that working with animals and … Continue reading Natural anomalies: when animals get in the way of science
Last week I was interviewed for the always interesting and entertaining Astrophiz podcast. I had a great time talking about my work, astrophysics, and science in general. Check it out: Astrophiz 51: Dr David Gozzard ~ Telescope pilot taking the pulse of the Universe
We Australians excel at remembering and celebrating our sporting heroes, from cricketers to particularly successful race horses, but are not so good at celebrating the great people who helped build our civilization, particularly when those builders are Australian. Today, I want to celebrate the birthday of an Australian aviation pioneer, Lawrence Hargrave. Aviation Pioneer Lawrence … Continue reading Great Australians — Lawrence Hargrave
This post was originally published by Australia's Science Channel on 29th July 2016 but was removed when the website was updated. David Gozzard is a PhD student who has found himself on an interesting journey to remote Australia. In this blog, he shares some of the fun work he's been up to! When I started my PhD in … Continue reading Radio Telescope on Track
We Australians excel at remembering and celebrating our sporting heroes, from cricketers to particularly successful race horses, but are not so good at celebrating the great people who helped build our civilization, particularly when those builders are Australian. Today, I want to celebrate the birthday of a revolutionary Australian engineer, A. G. M. Michell. … Continue reading Great Australians — Anthony Michell
Unless you live under a rock, the announcement in February of this year of the detection of Gravitational Waves by LIGO cannot have escaped your attention. Scientists around the world celebrated the achievement, and public curiosity about what all the scientists were yelling about was high enough that the world’s media ran the story for … Continue reading What the Detection of Gravitational Waves Means
We Australians excel at remembering and celebrating our sporting heroes, from cricketers to particularly successful race horses, but are not so good at celebrating the great people who helped build our civilization, particularly when those builders are Australian. Today, I want to celebrate the birthday of a brilliant Australian scientist, Ruby Payne-Scott. Southern Star … Continue reading Great Australians — Ruby Payne-Scott
Australia needs a space program. As 2015 drew to a close, Prime Minister Malcom Turnbull unveiled the government’s Innovation Statement with a plan to invest $1.1 billion to drive an Australian “ideas boom”. Before this announcement, the government had already commenced its Review of the Space Activities Act 1998 stating that Australia is in a transition … Continue reading Space for Innovation
