Did 513 pulsars reveal hints of ghostly dark matter?

Researchers analyzed polarized light from 513 pulsars using South Africa's MeerKAT telescope to hunt for ultralight dark matter. They mapped how the polarization angle shifts over time, separating expected effects (Earth's ionosphere, interstellar dust) from potential dark matter signatures using Bayesian statistics. While no smoking gun emerged, several pulsars showed rotation measure deviations worth following up.
