In an exciting leap forward for astronomy, researchers at the Breakthrough Listen initiative, in partnership with NVIDIA, have achieved a groundbreaking advancement in the search for Fast Radio Bursts (FRBs), developing an artificial intelligence system that dramatically outperforms existing detection methods while operating at unprecedented speeds. The new technology promises to revolutionize not only FRB astronomy but also the search for technosignatures – potential signals from extraterrestrial civilizations.
The system, detailed in the peer-reviewed journal Astronomy & Astrophysics (A deployed real-time end-to-end deep learning algorithm for fast radio burst detection, Astronomy & Astrophysics – open access), has been deployed on the Allen Telescope Array in California. It uses the NVIDIA Holoscan platform, developed for processing massive streaming datasets in diverse formats, leveraging the platform to process data in real-time without requiring traditional “dedispersion” techniques that search through thousands of possible signal parameters.
The performance improvements are staggering. The current state-of-the-art pipeline at the Allen Telescope Array requires approximately 59 seconds to process 16.3 seconds of observational data – running almost four times slower than real-time. The new end-to-end AI system processes the same data 600 times faster, enabling it to operate over 160 times faster than real-time constraints.
