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…
New candidate radio supernova remnants detected in the GLEAM survey over ,
Natasha Hurley-Walker, Miroslav D. Filipovic, Bryan M. Gaensler +18
We have detected 27 new supernova remnants (SNRs) using a new data release of the GLEAM survey from the Murchison Widefield Array (MWA) telescope, including the lowest surface-brig…
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…
The Murchison Widefield Array Commissioning Survey: A Low-Frequency Catalogue of 14,110 Compact Radio Sources over 6,100 Square Degrees
Natasha Hurley-Walker, John Morgan, Randall B. Wayth +49
We present the results of an approximately 6,100 square degree 104--196MHz radio sky survey performed with the Murchison Widefield Array during instrument commissioning between 201…
GaLactic and Extragalactic All-sky Murchison Widefield Array (GLEAM) survey II: Galactic Plane ,
Natasha Hurley-Walker, Paul J. Hancock, Thomas M. O. Franzen +16
This work makes available a further 2,860deg of the GLEAM survey, covering half of the accessible Galactic Plane, across twenty frequency bands sampling MHz, with resol…
Searching for Dark Matter Signals from Local Dwarf Spheroidal Galaxies at Low Radio Frequencies in the GLEAM Survey
Robin H. W. Cook, Nick Seymour, Kristine Spekkens +18
The search for emission from weakly interacting massive particle (WIMP) dark matter annihilation and decay has become a multi-pronged area of research not only targeting a diverse…
CHIPS: The Cosmological HI Power Spectrum Estimator
Cathryn M. Trott, Bart Pindor, Pietro Procopio +49
Detection of the cosmological neutral hydrogen signal from the Epoch of Reionization, and estimation of its basic physical parameters, is the principal scientific aim of many curre…

Natasha Hurley-Walker, Bryan M. Gaensler, Denis A. Leahy +18
We examined the latest data release from the GaLactic and Extragalactic All-sky Murchison Widefield Array (GLEAM) survey covering , $180^\circ < l < 240^\…
A numerical code for the solution of the Kompaneets equation in cosmological context
Pietro Procopio, Carlo Burigana
Context: The cosmic microwave background (CMB) spectrum probes physical processes and astrophysical phenomena occurring at various epochs of the Universe evolution. Current and fut…
