# DARA 21-cm Signal Simulation



## Overview



| DARA 21-cm Sim | A simple semi-numerical 21-cm signal simulation in a Jupyter notebook                                                                                                                                                   |

| Colab                 | [![Open in Google Colab](https://colab.research.google.com/assets/colab-badge.svg)](https://colab.research.google.com/github/ThomasGesseyJones/DARA_21cm_Signal_Simulation/blob/main/DARA_21cm_Signal_Simulation.ipynb) 



## Installation/Access Methods 



### Option 1

The simplest way to get your a copy of the workbook is to click the above *Open in Colab* link. 



### Option 2

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



### Option 3



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. 



### Option Avoiding Google Colab



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

## Acknowledgments



I would like to thank the organizers of the [2023 DARA Global 21-cm Astronomy Workshop](https://www.sarao.ac.za/news/student-workshop-on-global-21cm-astronomy-experiments-and-technology-to-be-held-in-february-2023/)

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](https://www.ast.cam.ac.uk/people/Anastasia.Fialkov), 

[Rennan Barkana](http://wise-obs.tau.ac.il/~barkana/), 

[Itamar Reis](https://github.com/ireis) 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](https://arxiv.org/abs/1003.3878), which remains an excellent more technical introduction to 21-cm signal 

simulations. 



Finally, I would like to thank [Christian Kirkham](https://beta-decay.github.io/) for his extensive testing of this workbook, and [Shikhar Mittal](https://sites.google.com/view/shikharmittal/home) for identifying a bug in an earlier version.
