Verifying the Australian MWA EoR pipeline I: 21-cm sky model and correlated measurement density
J. L. B. Line, C. M. Trott, J. H. Cook +3
We present the first of two papers dedicated to verifying the Australian Epoch of Reionisation pipeline (AusEoRPipe) through simulation. The AusEoRPipe aims to disentangle 21-cm ra…
The Impact of ionization Morphology and X-ray Heating on the Cosmological 21cm Skew Spectrum
J. H. Cook, S. Balu, B. Greig +4
The cosmological 21cm signal offers a potential probe of the early Universe and the first ionizing sources. Current experiments probe the spatially-dependent variance (Gaussianity)…
Multi-frequency angular power spectrum of the 21~cm signal from the Epoch of Reionisation using the Murchison Widefield Array
Cathryn M. Trott, Rajesh Mondal, Garrelt Mellema +5
The Multi-frequency Angular Power Spectrum (MAPS) is an alternative to spherically-averaged power spectra, and computes local fluctuations in the angular power spectrum without nee…
Murchison Widefield Array detection of steep-spectrum, diffuse, non-thermal radio emission within Abell 1127
Stefan W. Duchesne, Melanie Johnston-Hollitt, Zhenghao Zhu +2
Diffuse, non-thermal emission in galaxy clusters is increasingly being detected in low-frequency radio surveys and images. We present a new diffuse, steep-spectrum, non-thermal rad…
A search for long-timescale, low-frequency radio transients
Tara Murphy, David L. Kaplan, Steve Croft +30
We present a search for transient and highly variable sources at low radio frequencies (150-200 MHz) that explores long timescales of 1-3 years. We conducted this search by compari…
PUMA: The Positional Update and Matching Algorithm
J. L. B. Line, R. L. Webster, B. Pindor +2
We present new software to cross-match low-frequency radio catalogues: the Positional Update and Matching Algorithm (PUMA). PUMA combines a positional Bayesian probabilistic approa…
