Exploring the evolution of Reionisation using a wavelet transform and the light cone effect
Cathryn M. Trott
The Cosmic Dawn and Epoch of Reionisation, during which collapsed structures produce the first ionising photons and proceed to reionise the intergalactic medium, span a large range…
First Limits on the 21 cm Power Spectrum during the Epoch of X-ray heating
A. Ewall-Wice, Joshua S. Dillon, J. N. Hewitt +62
We present first results from radio observations with the Murchison Widefield Array seeking to constrain the power spectrum of 21 cm brightness temperature fluctuations between the…
The 154 MHz radio sky observed by the Murchison Widefield Array: noise, confusion and first source count analyses
T. M. O. Franzen, C. A. Jackson, A. R. Offringa +30
We analyse a 154 MHz image made from a 12 h observation with the Murchison Widefield Array (MWA) to determine the noise contribution and behaviour of the source counts down to 30 m…
Spectral calibration requirements of radio interferometers for Epoch of Reionisation science with the SKA
Cathryn M. Trott, Randall B. Wayth
Spectral features introduced by instrumental chromaticity of radio interferometers have the potential to negatively impact the ability to perform Epoch of Reionisation (EoR) and Co…
Limits on Fast Radio Bursts and other transient sources at 182 MHz using the Murchison Widefield Array
A. Rowlinson, M. E. Bell, T. Murphy +33
We present a survey for transient and variable sources, on timescales from 28 seconds to 1 year, using the Murchison Widefield Array (MWA) at 182 MHz. Down to a detection thr…
