Summary
👤
Senior🎓
Top SchoolCosimo Nigro is a postdoctoral researcher and software-focused gamma-ray astronomer based in Barcelona with nine years of experience building open-source tools for astrophysical data analysis. Trained as a particle physicist with a PhD from Humboldt-Universität zu Berlin, he combines rigorous instrumentation and spectral-analysis expertise with hands-on backend development for community projects like Gammapy and ROOT. His contributions include improving FITS variable-length array handling in ROOT and refining spectral and IRF functionality in Gammapy, demonstrating skill at turning complex scientific formats into reliable, test-covered code. As a part-time lecturer at Universitat Autònoma de Barcelona, he translates research-grade software into teachable methods and reproducible workflows. Colleagues know him for meticulous data-modeling work and a penchant for clear nomenclature and practical tutorials that lower the barrier to advanced gamma-ray analysis.

Contributions summary:Cosimo focused on enhancing the TFITS library, specifically handling variable-length arrays within FITS files. They made changes to accommodate reading and writing these arrays, including modifying the code to correctly handle offsets and sizes. The user also added a tutorial example demonstrating the use of variable-length arrays in FITS files, showing their ability to apply the core functionalities. Furthermore, they improved the nomenclature in TFITS.cxx.
