AI-enhanced Image of Black Hole Released by Scientists.

Scientists have used a machine learning technique called PRIMO to enhance the first-ever image of a supermassive black hole captured by the Event Horizon Telescope collaboration. PRIMO maximizes the resolving possibilities of the existing array of telescopes by using dictionary learning to teach computers specific rules. The technique was used to analyze over 30,000 high-fidelity simulated images of “gas accreting onto a black hole” to find common patterns among the tens of thousands of simulated images. The new image is consistent with the EHT data and with theoretical expectations, including the bright ring of emission expected to be produced by hot gas falling into the black hole.
