The Murchison Widefield Array Transients Survey (MWATS). A search for low frequency variability in a bright Southern hemisphere sample
M. E. Bell, Tara Murphy, P. J. Hancock +38
We report on a search for low-frequency radio variability in 944 bright (> 4Jy at 154 MHz) unresolved, extragalactic radio sources monitored monthly for several years with the Murc…
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…
A pilot survey for transients and variables with the Australian Square Kilometre Array Pathfinder
S. Bhandari, K. W. Bannister, T. Murphy +20
We present a pilot search for variable and transient sources at 1.4 GHz with the Australian Square Kilometre Array Pathfinder (ASKAP). The search was performed in a 30 deg ar…
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…
