Story summary
- New simulations show the Milky Way's core gamma ray glow may align with a dark matter signal, challenging prior theories.
- Johns Hopkins University researchers find that the inner dark matter halo is likely squashed rather than spherical, which could explain the gamma rays.
- Cherenkov Telescope Array Observatory observations planned for 2026 may determine if the glow is smooth or granular, clarifying the source per Physical Review Letters.
