"Revolutionary Telescope Unveils Secrets of Decaying Dark Matter in Ancient Cosmos"

A new study suggests that the Hydrogen Epoch of Reionization Array (HERA), a radio telescope in South Africa, could potentially detect evidence of decaying dark matter particles in the early universe. By observing the 21-centimeter line emitted by neutral hydrogen, HERA could detect the interaction of energetic decay particles from WIMPs (Weakly Interacting Massive Particles) with the hydrogen light. Even if no evidence of dark matter decay is found, HERA's observations would still provide valuable constraints on dark matter half-life and help narrow down the range of dark matter models.
