PROFILE
Tuomo Salmi
Worked on the xpsi-group/xpsi repository, delivering features and improvements for astrophysics simulation and scientific computing workflows. Over five months, contributed new tutorials, enhanced documentation, and implemented features such as ray-blocking for accretion disk modeling and stricter bounds in Gaussian model examples. Used Python, Jupyter Notebook, and Matplotlib to develop and document numerical models, improve code robustness, and expand learning resources. Addressed bugs related to geometry fidelity and syntax warnings, while refining release management and onboarding materials. Focused on maintainability, testing infrastructure, and clarity, resulting in more reliable simulations and streamlined developer experience for the xpsi scientific software platform.

Nov 1, 2025November 2025 performance summary for xpsi-group/xpsi: Delivered enhanced physical realism in accretion disk simulations by adding a ray-blocking feature that accounts for oblate star geometry and Schwarzschild-radius-based blocking, improving accuracy of accreting atmosphere modeling. Fixed a blocking-related bug by using cell-dependent b and r_g values for oblate-star geometry, increasing geometry fidelity. Updated documentation, changelog, and release notes, and expanded the accretion disk tutorial with new examples to support adoption. Overall impact includes higher fidelity simulations, more reliable results for researchers, clearer release communication, and reduced maintenance overhead through improved comments and versioning. Technologies/skills demonstrated include ray tracing algorithms, oblate geometry handling, Schwarzschild-radius concepts, codebase maintenance, documentation tooling, and release management.

Jan 1, 2025January 2025 — Focused on documentation quality and release-notes accuracy for the xpsi project. Delivered targeted documentation improvements and changelog editorial work to improve maintainability, onboarding, and release transparency. No runtime feature work or bug fixes were completed this month; the primary business value comes from clearer docs and release notes that reduce support costs and accelerate developer productivity. Key deliverables include release version bump in configuration, clarification of Everywhere class documentation, and editorial corrections to the CHANGELOG, plus a docstring comment addition.
