The Event Horizon Telescope (EHT) achieved the first horizon-scale image of a black hole by linking radio telescopes worldwide, forming a high-resolution, virtual telescope. This global collaboration of about 300 members uses advanced computational workflows, relying on Pegasus and the OSG OSPool to process vast data from EHT observations. Synthetic data generated in this pipeline aids in validating image reconstruction methods, analyzing black hole accretion flow effects, and aligning simulations with observations. EHT’s work involves substantial computational resources, processing petabytes of data, containerization, and cloud resources, with ongoing improvements to optimize workflows further.
