Hidden Star Systems in Milky Way May Hold Clues to Dark Matter

quick Summary

• researchers from the University of Surrey adn collaborators have uncovered the origins of globular clusters,dense stellar systems containing hundreds of thousands to millions of stars,using ultra-high-resolution EDGE simulations.
• Globular clusters lack dark matter and consist of stars uniform in age and chemical composition, features debated since their revelation in the 17th century.
• The simulations revealed two pathways for cluster formation and identified a new class of objects called “globular cluster-like dwarfs,” which may exist within our Milky Way.
• These newly identified star systems resemble regular globular clusters but contain dark matter, creating unique opportunities to study dark matter theories and early Universe formations.
• Satellites like Reticulum II could serve as prime locations for further exploration into metal-free stars and models surrounding dark matter.
• The team relied on advanced computational resources, DiRAC National Supercomputer facility included, to run EDGE simulations over several years at an unprecedented resolution (10 light years).
• Observations wiht telescopes such as James webb are planned to confirm these findings.
