Dark Matter spirals Found in Galaxy Simulations

New research indicates that dark matter, the mysterious substance comprising a meaningful portion of the universe, may exhibit spiral patterns within galaxies. These findings, derived from galaxy simulations, suggest a more active role for dark matter in galaxy evolution than previously understood.The study highlights the potential influence of dark matter on star formation and galactic rotation.
Scientists created simulations populated with particles representing stars, gas, and dark matter. By allowing these simulations to evolve over millions of years, researchers observed the emergence of dark matter spirals. These spirals, while less pronounced than their stellar counterparts, leave a distinct imprint on the motion of dark matter particles.
According to Bernet, the simulations allow scientists to observe cosmic events that unfold over timescales far exceeding human lifespans. The team validated their findings by identifying the same dark matter imprint across multiple self-reliant simulations.
The revelation suggests that dark matter’s influence extends beyond simply holding galaxies together. It appears to react to the gravity of stars within spiral arms, potentially affecting star formation and galactic rotation over vast cosmic periods. This could also explain the recently observed excess mass along a spiral arm in the Milky Way.
Brooks suggests the findings are significant because they change expectations for were to find dark matter signals in galaxies. “I think these results are very important because it changes our expectations for where to search for dark matter signals in galaxies,” Brooks saeid. “I could imagine that this result might influence our expectation for how dense dark matter is near the solar neighborhood and could influence expectations for lab experiments that are trying to directly detect dark matter.”
What’s next
Researchers aim to refine measurements of dark matter density within the Milky Way’s disk. Increased precision in these measurements could reveal spiral patterns, further substantiating the simulation results and providing new insights into the role of dark matter in shaping galaxies.
