The Radio Window on the Universe from Western Australia

20190405

Abstract. The radio regime is our largest ground based window on the Universe. Two new radio telescopes are exploiting the Western Australia’s remote location to survey the southern sky in unprecedented detail. Both of these telescope are scientific and technological precursor to the international Square Kilometre Array (SKA), an iconic science instrument for 21st century. These two telescopes, the Murchison Widefield Array (MWA) and the Australian SKA Pathfinder (ASKAP), are studying physical processes from the Earth’s magnetic field to the first black holes and galaxies. I will focus this talk on the wide range of exciting results from the MWA which is operated by Curtin University on behalf of an international consortium. In particular, I will focus on my study of radio galaxies: galaxies with luminous extended lobes of radio emission powered by super-massive black holes. My research has revolved around using radio galaxies to trace the evolution of galaxies and black holes across cosmic time.

Bio. After post-doctorial positions at Institut d’Astrophysics de Paris, (IPAC/JPL) and UCL, Dr. Nick Seymour was awarded an Australian Reseach Council Future Fellowship for work at the Australian Telescope National Facility in Sydney in 2011. Dr. Nick Seymour has a wide expertise in multi-wavelength extra-galactic astronomy and studies evolution of galaxies and how that interplays with their central black holes. He also has considerable experience in deep radio surveys and studies high redshift radio sources. Currently, he is Senior Lecturer at Curtin Institut of Radio Astronomy (Curtin University), working on MWA, ASKAP and planning for the SKA.
