Is That Dark Matter or Cosmic Noise? A New Algorithm Can Spot the Real Deal

A new deep-learning algorithm has been developed to differentiate dark matter interactions from cosmic noise. This algorithm, named Inception, can identify subtle signals of dark matter amidst the overwhelming feedback from cosmic sources like active galactic nuclei. The research, published in Nature Astronomy, highlights the potential of AI in advancing our understanding of dark matter, which constitutes about 27% of the universe yet remains invisible to traditional telescopes.

The algorithm was trained using images from the BAHAMAS-SIDM project, which models galaxy clusters under various scenarios. Inception achieved an impressive accuracy of 80% even when faced with observational noise, a common challenge in astronomical data. This innovative approach could significantly enhance data analysis from future telescopes, such as ESA's Euclid, enabling researchers to explore dark matter properties more efficiently.

• A deep-learning algorithm distinguishes dark matter from cosmic noise.
