Publicly available: 21cmGEM

Code 21cmGEM can be found here (Cohen, Fialkov, Barkana, Monsalve, 2019, submitted to MNRAS).

The code generates global 21-cm signal from Cosmic Dawn and Epoch of Reionization for an input set of 7 astrophysical parameters including star formation efficiency, minimum mass of star forming halos, X-ray efficiency, slope and minimum energy of the X-rays spectral energy distribution, CMB optical depth, ionizing efficiency of sources.

See Readme on how to run the code. The code is written in MATLAB and requires version 2014b or later with enabled Deep Learning Toolbox.
