Predicting Atmospheric Turbulence: The Key to Imaging Habitable Planets with Large Telescopes
Abstract:
Come and learn how GPUs help identify biological activity on nearby exoplanets. Deployed on on the Japanese Subaru telescope at 4,200m elevation atop Maunakea, Hawaii, the GPU hardware technology constitutes the backbone of the adaptive optics, which drives the real-time correction of the optical aberrations introduced by Earth's atmosphere. Using machine learning technique and advanced linear algebra algorithms accelerated by GPUs, a predictive control problem can now be solved at the multi-kHz frame rate required to keep up with turbulence changes. This represents the first successful on-sky result of this approach for exoplanet imaging.
