The Effect of Gravitational Lensing on Fast Transient Event Rates
Mawson W. Sammons, Clancy W. James, Cathryn M. Trott +1
Fast cosmological transients such as fast radio bursts (FRBs) and gamma-ray bursts (GRBs) represent a class of sources more compact than any other cosmological object. As such they…
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…
Optimising MWA EoR data processing for improved 21 cm power spectrum measurements -- fine-tuning ionospheric corrections
J. Kariuki Chege, C. H. Jordan, C. Lynch +4
The redshifted cosmological 21 cm signal emitted by neutral hydrogen during the first billion years of the universe is much fainter relative to other galactic and extragalactic rad…
Generating extremely large-volume reionisation simulations
Bradley Greig, J. Stuart B. Wyithe, Steven G. Murray +2
Preparing for the first detection of the cosmic 21-cm signal from large-scale interferometer experiments requires rigorous testing of the data analysis and reduction pipelines. To…
Investigating the Contribution of Extended Radio Sources to the Epoch of Reionisation Power Spectrum
J H. Cook, C. M. Trott, J. L. B. Line
We investigate the contribution of extended radio sources such as Centaurus A, and Galactic supernova remnants (SNRs) to our ability to detect the statistical signal…
System design and calibration of SITARA -- a global 21 cm short spacing interferometer prototype
Jishnu N. Thekkeppattu, Benjamin McKinley, Cathryn M. Trott +2
Global 21-cm experiments require exquisitely precise calibration of the measurement systems in order to separate the weak 21-cm signal from Galactic and extragalactic foregrounds a…
Imaging the Southern Sky at 159MHz using Spherical Harmonics with the Engineering Development Array 2
Michael A. Kriele, Randall B. Wayth, Mark J. Bentum +2
One of the major priorities of international radio astronomy is to study the early universe through the detection of the 21 cm HI line from the epoch of reionisation (EoR). Due to…
