Strong ionospheric activity at the MWA site associated with plasma bubble measured by GNSS
Shintaro Yoshiura, Yuichi Otsuka, Cathryn M. Trott +6
The Earth's ionosphere refracts radio signals, shifting the apparent position of radio sources. Wide-field measurements with a radio interferometer can measure the ionospheric dist…

Verifying the Australian MWA EoR pipeline II: fundamental limits of the AusEoRPipe and the impact of instrumental effects
J. L. B. Line, C. M. Trott, N. Barry +2
Detection of the weak cosmological signal from high-redshift hydrogen demands careful data analysis and an understanding of the full instrument signal chain. Here we use the WODEN…
