Linking dynamics and chemistry in barred galaxies through action-space mapping

This repository contains the data used in the paper "Linking dynamics and chemistry in barred galaxies through action-space mapping" by Asano, Debattista & Fujii (2026). Contents Data (target_MWa_01024.h5, target_model2.h5, donor_clumpy.h5, donor_m1cb.h5)Processed HDF5 files containing particlel positions, velocities, actions, donor assignment indices, and assigned chemical abundances ([Fe/H], [O/Fe]) for each target–donor pair. Code (example.ipynb)A Jupyter notebook demonstrating how to read the data files and reproduce bar side-on maps colour-coded by mean [Fe/H].
