"Einstein Rings and Dark Matter Mysteries Explored by Astrophysicists"

A new study suggests that axions, a type of force-carrying particle, may be a better explanation for dark matter than WIMPs (weakly interacting massive particles). While WIMPs have been the leading candidate for dark matter, their properties do not fully explain certain details on the scale of individual galaxies. Axions, on the other hand, have properties that are consistent with dark matter and may explain features in gravitational lensing that are difficult to explain with WIMPs. Axions interact with each other through quantum interference, creating wave-like patterns in their frequency throughout a galaxy.
