  Title:  Recent Results from the Australian SKA Site

  Speaker:  Prof Lister Staveley-Smith (University of Western Australia)

  Time:   May 6,3:30pm,Tuesday

  ABSTRACT: 

  The Australian SKA Pathfinder (ASKAP) and the Murchison Widefield Array (MWA) are the two precursor telescopes of the Square Kilometre Array (SKA) on the Western Australian site. The CSIRO ASKAP telescope is testing new phased array feed technology and will be the most powerful survey interferometer until the SKA. I will show some early results, summarise the science goals of the telescope and its relation to phase 1 of the SKA. MWA has already begun scheduled operations. I will summarise the science goals of the telescope, including the EOR and the GaLactic and Extragalactic All-sky MWA (GLEAM) survey for which I am principal investigator. GLEAM will investigate low-frequency emission from clusters, the cosmic web, relic radio galaxies, diffuse Galactic polarised emission, the Magellanic Clouds, nearby galaxies and Supernova Remnants. The ongoing execution of the GLEAM survey allows an interesting glimpse into the algorithmic and and dataflow challenges that await us when other sensitive widefield instruments such as FAST and Phase 1 of the SKA come on-line.
