AI Summary

Scientists have used gamma‑ray observations of the Milky Way’s center to set new limits on the rate at which dark matter particles might annihilate each other. The study examined data from the inner galaxy, where dark matter density is expected to be highest, and found no excess gamma‑ray signal above background expectations. These results tighten constraints on theoretical models that predict dark matter annihilation, but do not identify the particle composition of dark matter.
