Simulations find ghostly whirls of dark matter trailing galaxy arms
SMRTR summary
Astronomers have discovered dark matter spirals in galaxy simulations, mirroring stellar spiral arms but lagging behind them. This finding suggests dark matter actively responds to galactic gravity, potentially influencing star formation and rotation. The discovery could impact dark matter detection efforts and our understanding of galaxy evolution. Scientists hope to confirm these spirals in real galaxies through precise measurements of dark matter density in the Milky Way's disk.
