FlexKnot as a Generalised Model of the Sky-averaged 21-cm Signal at z ~ 6-30 in the Presence of Systematics

Emma Shen, Dominic Anstey, Eloy de Lera Acedo +1

Global 21-cm experiments are built to study the evolution of the Universe between the cosmic dawn and the epoch of reionisation. FlexKnot is a function parameterised by freely movi…

A Bayesian Method to Mitigate the Effects of Unmodelled Time-Varying Systematics for 21-cm Cosmology Experiments

Christian J. Kirkham, Dominic J. Anstey, Eloy de Lera Acedo

Radio observations of the neutral hydrogen signal from the Cosmic Dawn and Epoch of Reionisation have helped to provide constraints on the properties of the first stars and galaxie…

Enhanced Bayesian RFI Mitigation and Transient Flagging Using Likelihood Reweighting

Dominic Anstey, Samuel A. K. Leeney

Contamination by Radio Frequency Interference (RFI) is a ubiquitous challenge for radio astronomy. In particular, transient RFI is difficult to detect and avoid, especially in larg…

Modelling a Hot Horizon in Global 21 cm Experimental Foregrounds

Joe H. N. Pattison, Dominic J. Anstey, Eloy de Lera Acedo

The 21 cm signal from cosmic hydrogen is one of the most propitious probes of the early Universe. The detection of this signal would reveal key information about the first stars, t…

Receiver design for the REACH global 21-cm signal experiment

Ian L. V. Roque, Nima Razavi-Ghods, Steven H. Carey +35

We detail the the REACH radiometric system designed to enable measurements of the 21-cm neutral hydrogen line. Included is the radiometer architecture and end-to-end system simulat…
