The simplest way to get your a copy of the workbook is to click the above Open in Colab link.
You can also manually navigate to the link https://colab.research.google.com/github/ThomasGesseyJones/DARA_21cm_Signal_Simulation/blob/main/DARA_21cm_Signal_Simulation.ipynb
Open Google Colab, and when presented with the workbook selection pop-up window pick the GitHub tab. Then type into the search box ThomasGesseyJones/DARA it should automatically find the workbook and list it underneath 'Path'. Simply click on the workbook name and it will open a copy of the workbook.
Note for the DARA workshop it is recommended you use Google Colab since that way we don't have to worry about hardware requirements or any potential OS/version incompatibilities.
If you do not wish to use Google Colab, the workbook can be directly downloaded from this repository using git clone
or as a zip file by selecting the latest release. The .ipyb notebook file can then be opened in an interactive Jupyter
notebook environment of your choice.
For more information on how to get Jupyter running on your machine see https://jupyter.org/
I would like to thank the organizers of the 2023 DARA Global 21-cm Astronomy Workshop for giving me the opportunity to present, and finally giving me the motivation to make this workbook, something I have wanted to do for some time.
The structure of this code is inspired by the private 21-cm signal simulation code developed over many years by Anastasia Fialkov, Rennan Barkana, Itamar Reis and others who have my sincerest thanks for giving me access to said code and teaching me how to use and extend it. Several of the equations that are used have been modified from the original 21-cm FAST paper, which remains an excellent more technical introduction to 21-cm signal simulations.
Finally, I would like to thank Christian Kirkham for his extensive testing of this workbook, and Shikhar Mittal for identifying a bug in an earlier version.
If you have any feedback on the workbook or would like to contribute to it feel free to contact me at tg400@cam.ac.uk or open an issue or pull request on this here repository.
