Summary
👤
Senior🎓
Top SchoolAlexandre Beelen is an observational cosmologist and assistant astronomer with 10+ years leading instrument-driven data analysis for (sub)mm and radio observations of high-redshift galaxies, quasars and reionization-era star formation. He has steered development of key map-making and bolometer analysis software (SANEPIC, BOA-related tools) for projects on APEX and Herschel and has deep practical experience applying these pipelines to large surveys like H-ATLAS and HerMES/GOODS-H. His work bridges hands-on instrument stewardship, code development in Python/C/C++ and scientific analysis, and includes a notable open-source contribution to Astropy implementing thermodynamic temperature equivalencies for Jy/beam conversions. Trained through research positions at MPIfR, IAP, and IAS and educated in top French institutions, he pairs strong observational skills with teaching experience from IRAM schools to university classes. Colleagues value him for turning complex radiometric calibration and map-making challenges into reproducible software and validated science products. Based in Marseille, he continues to push methods that link galaxy clustering, environment and dust/gas physics at high redshift.

Contributions summary:Alexandre primarily contributed to the `astropy` repository by implementing and refining a thermodynamic temperature equivalency within the unit conversion functionalities. They focused on converting between Jy/beam and thermodynamic temperature, including necessary calculations and references. Their work involved modifying existing code, including adjusting parameters based on feedback, and adding tests to ensure the accuracy of these unit conversions. This work directly supports astronomical data analysis within the Astropy library.
