A Roadmap for Astrophysics and Cosmology with High-Redshift 21 cm Intensity Mapping
The Hydrogen Epoch of Reionization Array, Collaboration, James E. Aguirre +29
In this white paper, we lay out a US roadmap for high-redshift 21 cm cosmology (30 < z < 6) in the 2020s. Beginning with the currently-funded HERA and MWA Phase II projects and adv…
hankel: A Python library for performing simple and accurate Hankel transformations
Steven G. Murray, Francis J. Poulin
This paper presents \textsc{hankel}, a pure-python code for solving Hankel-type integrals and transforms. Such transforms are common in the physical sciences, especially appearing…
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…
Robust statistics toward detection of the 21 cm signal from the Epoch of Reionisation
Cathryn M. Trott, Shih Ching Fu, Steven Murray +26
We explore methods for robust estimation of the 21 cm signal from the Epoch of Reionisation (EoR). A Kernel Density Estimator (KDE) is introduced for measuring the spatial temperat…
Eddington's Demon: Inferring Galaxy Mass Functions and other Distributions from Uncertain Data
Danail Obreschkow, Steven G. Murray, Aaron S. G. Robotham +1
We present a general modified maximum likelihood (MML) method for inferring generative distribution functions from uncertain and biased data. The MML estimator is identical to, but…
Characterisation of the ionosphere above the Murchison Radio Observatory using the Murchison Widefield Array
C. H. Jordan, S. Murray, C. M. Trott +6
We detail new techniques for analysing ionospheric activity, using Epoch of Reionisation (EoR) datasets obtained with the Murchison Widefield Array (MWA), calibrated by the `Real-T…
