The GLEAM 4-Jy (G4Jy) Sample: III. Further host-galaxy identification, and redshift assessment
Sarah V. White, Precious K. Sejake, Kshitij Thorat +17
In this paper we present 127 new host-galaxy identifications for G4Jy sources (S_151MHz > 4 Jy), based on radio images from MeerKAT, the Very Large Array Sky Survey (VLASS), and th…
The GLEAM 4-Jy (G4Jy) Sample: IV. Multiwavelength data and analysis
Sarah V. White, Precious K. Sejake, Kshitij Thorat +17
We provide an updated 'multiwavelength' version of the G4Jy catalogue (available at https://github.com/svw26/G4Jy, https://zenodo.org/communities/g4jy/records, and through VizieR),…
Spectral Variability of Radio Sources at Low Frequencies
K. Ross, J. R. Callingham, N. Hurley-Walker +7
Spectral variability of radio sources encodes information about the conditions of intervening media, source structure, and emission processes. With new low-frequency radio interfer…
A Low Frequency Blind Survey of the Low Earth Orbit Environment using Non-Coherent Passive Radar with the Murchison Widefield Array
Steve Prabu, Paul J Hancock, Zhang Xiang +1
We have extended our previous work to use the Murchison Widefield Array (MWA) as a non-coherent passive radar system in the FM frequency band, using terrestrial FM transmitters to…
SMSS J130522.47-293113.0: a high-latitude stellar X-ray source with pc-scale outflow relics?
G. S. Da Costa, R. Soria, S. A. Farrell +17
We report the discovery of an unusual stellar system, SMSS J130522.47-293113.0. The optical spectrum is dominated by a blue continuum together with emission lines of hydrogen, neut…
Follow up of GW170817 and its electromagnetic counterpart by Australian-led observing programs
I. Andreoni, K. Ackley, J. Cooke +122
The discovery of the first electromagnetic counterpart to a gravitational wave signal has generated follow-up observations by over 50 facilities world-wide, ushering in the new era…
Extragalactic Peaked-Spectrum Radio Sources at Low Frequencies
J. R. Callingham, R. D. Ekers, B. M. Gaensler +21
We present a sample of 1,483 sources that display spectral peaks between 72 MHz and 1.4 GHz, selected from the GaLactic and Extragalactic All-sky Murchison Widefield Array (GLEAM)…
Galactic synchrotron emissivity measurements between 250° < l < 355° from the GLEAM survey with the MWA
H. Su, N. Hurley-Walker, C. A. Jackson +20
Synchrotron emission pervades the Galactic plane at low radio frequencies, originating from cosmic ray electrons interacting with the Galactic magnetic field. Using a low-frequency…
GaLactic and Extragalactic All-sky Murchison Widefield Array (GLEAM) survey I: A low-frequency extragalactic catalogue
Natasha Hurley-Walker, Joseph R. Callingham, Paul J. Hancock +40
Using the Murchison Widefield Array (MWA), the low-frequency Square Kilometre Array (SKA1 LOW) precursor located in Western Australia, we have completed the GaLactic and Extragalac…
Ionospheric Modelling using GPS to Calibrate the MWA. II: Regional ionospheric modelling using GPS and GLONASS to estimate ionospheric gradients
B. S. Arora, J. Morgan, S. M. Ord +18
We estimate spatial gradients in the ionosphere using the Global Positioning System (GPS) and GLONASS (Russian global navigation system) observations, utilising data from multiple…
Low Radio Frequency Observations and Spectral Modelling of the Remnant of Supernova 1987A
J. R. Callingham, B. M. Gaensler, G. Zanardo +17
We present Murchison Widefield Array observations of the supernova remnant (SNR) 1987A between 72 and 230 MHz, representing the lowest frequency observations of the source to date.…
