Software

This page highlights the software and numerical tools I’ve developed or contributed to while researching galaxy-scale simulations, dust physics, and multiphase feedback processes.

🧩 Developed Software

Osaka-Gadget4

A modified version of Gadget-4 tailored for high-resolution simulations of galactic environments, developed in collaboration with Y. Oku and K. Matsumoto.

Key features include:

• A dust grain-size evolution model
• Self-interacting dark matter (SIDM) physics module
• State-of-the-art stellar feedback models
• Numerous upgrades and patches to core SPH routines in Gadget-4

🔒 Repository access is currently restricted due to data sharing policies. Available to collaborators upon request.

🔧 Contributions to Open-Source Projects

Grackle-3 (v3.2)
