The MWA Interestingly Deep AStrophysical (MIDAS) Survey: Survey Description and First Data Release
S. Paterson, N. Seymour, N. Hurley-Walker +4
We present the deepest MWA survey to date, targeting the GAMA9 and GAMA23 survey fields at 215.68 MHz. With a bandwidth of 30.72 MHz, the two images cover …
GaLactic and Extragalactic All-sky Murchison Widefield Array survey eXtended (GLEAM-X) III: Galactic Plane
S. Mantovanini, N. Hurley-Walker, K. Ross +3
We present the third data release for the Galactic and Extragalactic All-Sky Murchison Widefield Array eXtended (GLEAM-X) survey, covering = 3800 deg2 of the southern Galactic Plan…
GLEAM-300: The GaLactic and Extragalactic All-sky Murchison Widefield Array (GLEAM) survey at 300 MHz
S. W. Duchesne, J. H. Cook, N. Hurley-Walker +11
In this paper we present a wide-field radio survey at 300 MHz covering the sky from using the Murchison Widefield Array (MWA). Th…
Low radio frequency detections of known pulsars and identification of new candidates with GLEAM-X: GP
Silvia Mantovanini, N. Hurley-Walker, G. Anderson +3
Image-based searches have become a complementary approach for identifying pulsars, particularly at MHz frequencies where scattering and high dispersion measures affect high-time re…
Supernova remnant candidates identified using MWA Galactic Plane Monitoring over 285deg < l < 70deg and |b| < 16deg
S. Mantovanini, N. Hurley-Walker, G. E. Anderson
Observations of Galactic supernova remnants (SNRs) are crucial to understanding supernova explosion mechanisms and their impact on our Galaxy's evolution. SNRs are usually identifi…
GaLactic and Extragalactic All-sky Murchison Widefield Array eXtended (GLEAM-X) survey II: Second Data Release
K. Ross, N. Hurley-Walker, T. J. Galvin +9
We present the second data release for the GaLactic and Extragalactic All-sky Murchison Widefield Array eXtended (GLEAM-X) survey. This data release is an area of 12,892-deg^2 arou…
Low-frequency absorption and radio recombination line features of the Galactic Center Lobe
Natasha Hurley-Walker, L. D. Anderson, M. Luisi +6
The Galactic center lobe (GCL) is a object located north of the Galactic center. In the mid-infrared (MIR), the GCL appears as two 8.0-micron filaments that roughly…
The Galactic Center Lobe as an HII Region
L. D. Anderson, Matteo Luisi, B. Liu +5
The Galactic center lobe (GCL) is an object ~1° across that is located north of the Galactic center. In the mid-infrared (MIR) the GCL appears as two 8.0m filaments between whic…
AGN energetics and lifetimes from remnant radio galaxies
Benjamin Quici, Ross J. Turner, Nicholas Seymour +1
The energy coupling efficiency of active galactic nucleus (AGN) outbursts is known to {vary} significantly with factors including the jet kinetic power, duration of the outburst, a…
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…
A Molecular Line Survey around Orion at Low Frequencies with the MWA
Chenoa D. Tremblay, Paul A. Jones, Maria Cunningham +3
The low-frequency sky may reveal some of the secrets yet to be discovered and until recently, molecules had never been detected within interstellar clouds at frequencies below 700M…
Broadband Spectral Modeling of the Extreme Gigahertz-Peaked Spectrum Radio Source PKS B0008-421
J. R. Callingham, B. M. Gaensler, R. D. Ekers +40
We present broadband observations and spectral modeling of PKS B0008-421, and identify it as an extreme gigahertz-peaked spectrum (GPS) source. PKS B0008-421 is characterized by th…
