21cmFAST v3: A Python-integrated C code forgenerating 3D realizations of the cosmic 21cm signal
Steven G. Murray, Bradley Greig, Andrei Mesinger +4
This brief code paper presents a new Python-wrapped version of the popular 21cm cosmology simulator, 21cmFAST. The new version, v3+, maintains the same core functionality of previo…
The bispectrum and 21cm foregrounds during the Epoch of Reionization
Catherine A Watkinson, Cathryn M Trott, Ian Hothi
Numerous studies have established the theoretical potential of the 21cm bispectrum to boost our understanding of the Epoch of Reionization (EoR), and therefore early generation of…
The 21cm bispectrum during reionization: a tracer of the ionization topology
Anne Hutter, Catherine A. Watkinson, Jacob Seiler +3
We compute the bispectra of the 21cm signal during the Epoch of Reionization for three different reionization scenarios that are based on a dark matter N-body simulation combined w…
Gridded and direct Epoch of Reionisation bispectrum estimates using the Murchison Widefield Array
Cathryn M. Trott, Catherine A. Watkinson, Christopher H. Jordan +42
We apply two methods to estimate the 21~cm bispectrum from data taken within the Epoch of Reionisation (EoR) project of the Murchison Widefield Array (MWA). Using data acquired wit…
Evaluating machine learning techniques for predicting power spectra from reionization simulations
William D. Jennings, Catherine A. Watkinson, Filipe B. Abdalla +1
Upcoming experiments such as the SKA will provide huge quantities of data. Fast modelling of the high-redshift 21cm signal will be crucial for efficiently comparing these data sets…
The 21cm bispectrum as a probe of non-Gaussianities due to X-ray heating
Catherine A. Watkinson, Sambit K. Giri, Hannah E. Ross +4
We present analysis of the normalised 21-cm bispectrum from fully-numerical simulations of intergalactic-medium heating by stellar sources and high-mass X-ray binaries (HMXB) durin…
