The SKA Mid-frequency All-sky Continuum Survey: Discovering the unexpected and transforming radio-astronomy
Ray P. Norris, Kaustuv Basu, Michael Brown +5
We show that, in addition to specific science goals, there is a strong case for conducting an all-sky (i.e. the visible 3-pi steradians) SKA continuum survey which does not fit nea…
The Spectral Variability of the GHz-Peaked Spectrum Radio Source PKS 1718-649 and a Comparison of Absorption Models
S. J. Tingay, J. -P. Macquart, J. D. Collier +42
Using the new wideband capabilities of the Australia Telescope Compact Array (ATCA), we obtain spectra for PKS 1718-649, a well-known gigahertz-peaked spectrum radio source. The ob…
A Unified Model of the Fermi Bubbles, Microwave Haze, and Polarized Radio Lobes: Reverse Shocks in the Galactic Center's Giant Outflows
Roland M. Crocker, Geoffrey V. Bicknell, Andrew M. Taylor +1
The Galactic Center's giant outflows are manifest in three different, non-thermal phenomena: i) the hard-spectrum, γ-ray `Fermi Bubbles' emanating from the nucleus and extending to…
First Look Murchison Widefield Array observations of Abell 3667
L. Hindson, M. Johnston-Hollitt, N. Hurley-Walker +51
The Murchison Widefield Array (MWA) is a new low frequency interferometric radio telescope, operating in the remote Murchison Radio Observatory in Western Australia. In this paper…
The first Murchison Widefield Array low frequency radio observations of cluster scale non-thermal emission: the case of Abell 3667
L. Hindson, M. Johnston-Hollitt, N. Hurley-Walker +51
We present the first Murchison Widefield Array observations of the well-known cluster of galaxies Abell 3667 (A3667) between 105 and 241 MHz. A3667 is one of the best known example…
Galactic interstellar turbulence in the southern sky seen through spatial gradients of the polarization vector
M. Iacobelli, B. Burkhart, M. Haverkorn +7
Radio synchrotron polarization maps of the Galaxy can be used to infer the properties of interstellar turbulence in the diffuse warm ionized medium (WIM). In this paper, we investi…
