Welcome to the repository for Dubay et al. (2024), "Galactic Chemical Evolution Models Favor an Extended Type Ia Supernova Delay-Time Distribution", arXiv:2404.08059.

To re-build the article yourself, simply run the following from the repository directory:

$ showyourwork build

The data and model outputs will automatically be downloaded from the Zenodo deposit.

To re-create the APOGEE sample with Leung et al. (2023) age estimates, run the following:

$ python generate_sample.py

This will replace everything in the src/data/APOGEE directory.

To re-run all models yourself, run the following:

$ python run_all_models.py

This will replace everything in the src/data/multizone directory, including the output files from Zenodo.

Source code for the models is located within the src/scripts/multizone/ directory. To run a single multi-zone model with custom parameters, run the following:

$ cd src/scripts
$ python -m multizone [OPTIONS...]

In particular, code for the stellar migration prescription is contained within the gaussian_migration class located at src/scripts/multizone/src/migration.py.
