Major milestone for key radio-astronomy project

…lestone in its ongoing development, with the building and deployment of equipment for its Phase Two expansion now complete. In an operation that has taken nearly 16 months, 128 new antenna stations have been assembled on the MWA site by a team of MWA operations staff, students from Curtin University and international project partners, as well as Geraldton contractors GCo Electrical. This latest addition to the Curtin University-led MWA, brings…

Curtin researcher named WA Young Tall Poppy Scientist of the Year 2017

…he is a great advocate for science, and has visited many schools to introduce primary school children to astronomy, as well as giving high school students advice about pursuing a career in science.” Dr Hurley-Walker used the MWA to survey the entire southern sky for the GaLactic and Extragalactic All-sky MWA (GLEAM) survey, offering astronomers the first ‘radio colour’ view of the low-frequency sky. She has also given keynote talks at Astrofest,…

Curtin University plays important role in worldwide cosmic event

…sive stars explode in supernovas. They are the smallest, densest stars known to exist with one teaspoon of neutron star material weighing more than a billion tonnes. Also part of the search was the Murchison Widefield Array (MWA) radio telescope international consortium, led by MWA Director and Curtin University Associate Professor, Randall Wayth. “Once we received notification of the event, the widefield nature of the MWA allowed us to search…

2017 Research and Engagement Award winners

…the Faculty of Health Sciences Associate Professor Suzanne Robinson from the Faculty of Health Sciences, and; MWA GLEAM team from the Faculty of Science & Engineering The winner of the award, valued at $ 10,000, was the MWA GLEAM team: Natasha Hurley-Walker, Paul Hancock, John Morgan, Steven Tingay, Andrew Williams, Carol Jackson, Cathryn Trott, David Emrich, Ron Ekers, Steve Ord and Tom Franzen. The GaLactic and Extragalactic All-sky MWA

Leading radio astronomer back in Perth’s orbit

…chison Widefield Array SKA precursor and our astrophysics and engineering capabilities at Curtin, we are in a very strong position for the future, with a world renowned reputation.” Professor Tingay was Director of CIRA from 2007-2015, Deputy Director of the International Centre for Radio Astronomy Research (ICRAR) from 2009-2015, and Director of the Murchison Widefield Array (MWA) project from 2011-2015. He represented Italy on the SKA Board in…

Astronomers hazard a ride in a ‘drifting carousel’ to understand pulsating stars

…rticles, arranged in a rotating ring around magnetic field lines, or a carousel. “As each patch releases radiation, the rotation generates a small drift in the observed signal of these sub-pulses that we can detect using the MWA,” Mr McSweeney said. “Occasionally, we find that this sub-pulse carousel gets faster and then slower again, which can be our best window into the plasma physics underlying the pulsar emission.” One possibility the…

Flash of invisible light helps astronomers map the cosmic web

…Bs remain one of the most mysterious processes in the Universe and likely one of the most energetic ones. To catch more FRBs, astronomers use new technology, such as Parkes’ multibeam receiver, the Murchison Widefield Array (MWA) in Western Australia, and the upgraded Molonglo Observatory Synthesis Telescope near Canberra. This particular FRB was found and analysed by a system developed by the supercomputing group led by Professor Matthew Bailes…

Australian desert telescope views sky in radio technicolour

…are extremely valuable to scientists and they’re used across many areas of astrophysics, often in ways the original researchers could never have imagined,” Associate Professor Wayth said. Completing the GLEAM survey with the MWA is a big step on the path to SKA-low, the low frequency part of the international Square Kilometre Array (SKA) radio telescope to be built in Australia in the coming years. “It’s a significant achievement for the MWA

Curtin’s out of this world efforts in Eureka moment

…perfect demonstration of Curtin’s strong contributions to building fundamental knowledge about our solar system and beyond, but also how Curtin engages with the broader community to achieve innovative research outcomes.” The MWA is a low frequency radio telescope built and operated by an international consortium of universities and research institutions. Designed to pursue the highest priority goals in cosmology, the MWA is a versatile…

High tech partnership paying off

…(ICRAR), explained that the AARnet-Cisco 100Gb/s data link would allow data to be shipped to the Cisco IoE Innovation Centre over optical fibres without ‘regeneration’, meaning that once signals are converted to light at the MWA, they then travel as light all the way to Perth. Many such links would be used in parallel for the SKA, using already-installed optical fibre. “In addition to incurring lower maintenance costs and using easily available,…
