Sample Variance Denoising in Cylindrical 21-cm Power Spectra
Daniela Breitman, Andrei Mesinger, Steven G. Murray +1
State-of-the-art simulations of reionisation-era 21-cm signal have limited volumes, generally orders of magnitude smaller than observations. Consequently, the Fourier modes in comm…

Efficient simulation of discrete galaxy populations and associated radiation fields during the first billion years
James E. Davies, Andrei Mesinger, Steven Murray
Understanding the epochs of cosmic dawn and reionisation requires us to leverage multi-wavelength and multi-tracer observations, with each dataset providing a complimentary piece o…

The EDGES measurement disfavors an excess radio background during the cosmic dawn
Junsong Cang, Andrei Mesinger, Steven G. Murray +3
In 2018 the EDGES experiment claimed the first detection of the global cosmic 21cm signal, which featured an absorption trough centered around with a depth of approxima…
