During October 2025, JT Umlins expanded the hydrogen H2 numerical root track data infrastructure within the foggie-sims/foggie repository. They developed new root track files to capture H2 simulation data across multiple halo tracks and redshift outputs, enhancing the project’s data collection and tracking capabilities. This work involved advanced data management and scientific simulation techniques, leveraging Python and domain-specific data processing tools to ensure robust integration with existing analytics workflows. The feature addressed the need for more comprehensive H2 tracking, enabling downstream analysis and research. The depth of the implementation reflects careful attention to simulation data structure and scientific reproducibility.
