The POlarised GLEAM Survey (POGS) I: First Results from a Low-Frequency Radio Linear Polarisation Survey of the Southern Sky
C. J. Riseley, E. Lenc, C. L. Van Eck +7
The low-frequency polarisation properties of radio sources are poorly studied, particularly in statistical samples. However, the new generation of low-frequency telescopes, such as…
Galactic synchrotron distribution derived from 152 HII region absorption features in the full GLEAM survey
H. Su, J. P. Macquart, N. Hurley-Walker +22
We derive the synchrotron distribution in the Milky Way disk from HII region absorption observations over -40° < l < 40° at six frequencies of 76.2, 83.8, 91.5, 99.2, 106.9, and 11…
An all-sky survey of circular polarisation at 200 MHz
Emil Lenc, Tara Murphy, Christene R. Lynch +2
We present results from the first all-sky radio survey in circular polarisation. The survey uses the Murchison Widefield Array (MWA) to cover 30900 sq. deg., over declinations sout…
High-resolution Observations of Low-luminosity Gigahertz-Peaked Spectrum and Compact Steep Spectrum Sources
Jordan D. Collier, Steven J. Tingay, Joseph R. Callingham +27
We present Very Long Baseline Interferometry observations of a faint and low-luminosity ($L_{\rm 1.4 GHz} < 10^{27}~\mbox{W Hz}^{-1}$) Gigahertz-Peaked Spectrum (GPS) and Compact S…
Faraday rotation at low frequencies: magnetoionic material of the large FRII radio galaxy PKS J0636-2036
Shane P. O'Sullivan, Emil Lenc, Craig S. Anderson +2
We present a low-frequency, broadband polarization study of the FRII radio galaxy PKS J0636-2036 (z = 0.0551), using the Murchison Widefield Array (MWA) from 70 to 230 MHz. The nor…
