Limits on Unintended Radio Emission from Geostationary and Geosynchronous Satellites in the SKA-Low Frequency Range
S. J. Tingay, N. Hurley-Walker, K. Ross +3
We search data from the GLEAM-X survey, obtained with the Murchison Widefield Array (MWA) in 2020, for the presence of radio frequency interference from distant Earth-orbiting sate…
A long period transient search method for the Murchison Widefield Array
Csanád Horváth, Natasha Hurley-Walker, Samuel J. McSweeney +2
We present an automated search method for radio transients on the minute timescale focused on the emerging long period transients (LPTs) in image-plane radio data. The method is tu…
A new long period radio transient: Discovery of pulses repeating every 1.16 hours from ASKAP J175534.9-252749.1
Samuel J. McSweeney, Natasha Hurley-Walker, Csanád Horváth +7
We report the discovery of several new pulses from the source ASKAP J175534.9-252749.1 (J1755-2527), originally identified from a single 2-min long pulse, confirming it as a long p…
A nanosecond-duration radio pulse originating from the defunct Relay 2 satellite
C. W. James, A. T. Deller, T. Dial +14
We report the detection of a burst of emission over a 695.5 MHz-1031.5 MHz bandwidth by the Australian Square Kilometre Array Pathfinder, ASKAP. The burst was localised through ana…
