Tools21cm: A python package to analyse the large-scale 21-cm signal from the Epoch of Reionization and Cosmic Dawn


Giri, Sambit; Mellema, Garrelt; Jensen, Hannes (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.

Abstract

The Cosmic Dawn (CD) and Epoch of Reionization (EoR) are among the least understoodepochs from the history of our Universe. Large-scale cosmological simulations are useful tounderstand this era and help prepare for future observations.Tools21cmis a data manipu-lation and analysis package for studying such cosmological simulations. It is written in thepython programming language and designed to be very user-friendly.The 21-cm signal, produced by the spin-flip transition of neutral hydrogen, is a unique tracerof matter in large-scale structures present during the EoR and CD (e.g. Furlanetto, Oh, &Briggs, 2006; Pritchard & Loeb, 2012). This signal will be cosmologically redshifted andthus found at low radio frequencies. Much of the functionality ofTools21cmis focusedon the construction and analysis of mock 21-cm observations in the context of current andupcoming 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), HydrogenEpoch of Reionization Array (HERA; DeBoer et al., 2017) and the Square Kilometre Array(SKA; Mellema et al., 2013).Tools21cmpost-processes cosmological simulation data tocreate mock 21-cm observations
