Here [EMRI_Waveforms_in_a_nuthsell.ipynb] you can find a pedagogical tutorial on creating Extreme Mass Ratio Inspiral (EMRI) waveforms. We will make an extensive use of the Fast EMRI Waveform (FEW) package arxiv.org/2104.04582 arxiv.org/2008.06071. Install the FEW package before running the notebook. The installation instructions can be found on Github here. The waveforms in this package combine a variety of separately accessible modules to form EMRI waveforms on both CPUs and GPUs. Generally, the modules fall into four categories: trajectory, amplitudes, summation, and utilities. Please see the documentation for further information on these modules.

If you use all or any parts of this code, please cite arxiv.org/2104.04582 and arxiv.org/2008.06071. See the documentation to properly cite specific modules.

[BeyondVacuum-EMRIs.ipynb] is a tutorial based on the previous notebook and it shows how to modify an EMRI trajectory in order to include additional effects beyond vacuum.
