      Raccanelli, Alvise; Zhao, Gong-Bo; Bacon, David J.; Jarvis, M.J.; Percival, Will J.; Norris, Ray P.; Rottgering, Huub; Abdalla, Filipe B.; Cress, Catherine M.; Kubwimana, Jean-Claude; Lindsay, Sam; Nichol, Robert C.; Santos, Mario G.; Schwarz, Dominik J. (2012-08)
      We present forecasts for constraints on cosmological models that can be obtained using the forthcoming radio continuum surveys: the wide surveys with the Low Frequency Array (LOFAR) for radio astronomy, the Australian ...

(2011)
      EMU is a wide-field radio continuum survey planned for the new Australian Square Kilometre Array Pathfinder (ASKAP) telescope. The primary goal of EMU is to make a deep (rms ~ 10 microJy/beam) radio continuum survey of the ...

    • Radio galaxy zoo EMU: towards a semantic radio galaxy morphology taxonomy 

      Bowles, Micah; Tang, Hongming; Vardoulaki, Eleni; Alexander, Emma L.; Luo, Yan; Rudnick, Lawrence; Walmsley, Mike; Porter, Fiona; Scaife, Anna M.~M.; Slijepcevic, Inigo Val; Adams, Elizabeth A.~K.; Drabent, Alexander; Dugdale, Thomas; Gürkan, Gülay; Hopkins, Andrew M.; Jimenez-Andrade, Eric F.; Leahy, Denis A.; Norris, Ray P.; Rahman, Syed Faisal ur; Ouyang, Xichang; Segal, Gary; Shabala, Stanislav S.; Wong, O. Ivy (2023-04-11)
      We present a novel natural language processing (NLP) approach to deriving plain English descriptors for science cases otherwise restricted by obfuscating technical terminology. We address the limitations of common radio ...

    • The Spectral Energy Distribution of Powerful Starburst Galaxies I : Modelling the Radio Continuum 

      Galvin, T J; Seymour, N.; Marvil, J.; Filipovic, M D; Tothill, N.F.H.; McDermid, Richard M.; Hurley-Walker, N.; Hancock, P. J.; Callingham, J.

R.; Procopio, P.; Staveley-Smith, L.; Wayth, R. B.; Wu, C.; Zheng, Q. (2018-02-01)
      We have acquired radio-continuum data between 70MHz and 48 GHz for a sample of 19 southern starburst galaxies at moderate redshifts (0.067 < z < 0.227) with the aim of separating synchrotron and free-free emission components. ...
