I'm Freek Roelofs, an astrophysicist at Radboud University in Nijmegen, the Netherlands. I work on imaging black holes with radio telescopes in the Event Horizon Telescope Colloboration, using the technique of Very Long Baseline Interferometry (VLBI).
🛰️🌍🛰️ I develop the svlbisim toolkit to simulate Space VLBI observations.
🦁 I developed the SYMBA synthetic data generation pipeline, simulating the end-to-end VLBI observation and calibration process from physical principles.
📡🌍📡 I coordinate the ngEHT Analysis Challenges, investigating black hole imaging, movie making, and parameter inference algorithms for the Next-Generation EHT.
