Abstract

Giri et al., (2020). Tools21cm: A python package to analyse the large-scale 21-cm signal from the Epoch of Reionization and Cosmic Dawn. Journal of Open Source Software, 5(52), 2363, https://doi.org/10.21105/joss.02363

Highlights

  • The Cosmic Dawn (CD) and Epoch of Reionization (EoR) are among the least understood epochs from the history of our Universe

  • Much of the functionality of Tools21cm is focused on the construction and analysis of mock 21-cm observations in the context of current and upcoming radio telescopes, such as the Low Frequency Array (LOFAR; Haarlem et al, 2013), the Murchison Widefield Array (MWA; Tingay et al, 2013; Wayth et al, 2018), Hydrogen Epoch of Reionization Array (HERA; DeBoer et al, 2017) and the Square Kilometre Array (SKA; Mellema et al, 2013)

  • A sequence of such images from different redshifts is known as a tomographic data set and is three dimensional

Summary

Introduction

The Cosmic Dawn (CD) and Epoch of Reionization (EoR) are among the least understood epochs from the history of our Universe. Large-scale cosmological simulations are useful to understand this era and help prepare for future observations. Tools21cm is a data manipulation and analysis package for studying such cosmological simulations.
