Title: Unlocking Black Hole Physics With Computational Astronomy
Abstract: By utilizing a network of global radio telescopes in April 2019, the Event Horizon Telescope (EHT) took the first picture of a black hole. Unlike other areas of astronomy, every step of the observation process, including the formation of the telescope, calibration, and imaging, depends on software and high-performance computation. In this talk, I will review the computational aspects of the first-ever image of a black hole and how computational and algorithmic improvements can significantly accelerate radio science. Furthermore, I will review how we can combine machine learning with physically informed models to sharpen our images and extract information about black hole spacetimes.
