An international team of researchers with key participation from the PRISMA+Cluster of Excellence at Johannes Gutenberg University Mainz (JGU) and the Helmholtz Institute Mainz (HIM) has published for the first time comprehensive data on the search for dark matter using a worldwide network of optical magnetometers. According to the scientists, dark matter fields should produce a characteristic signal pattern that can be detected by correlated measurements at multiple stations of the GNOME network. Analysis of data from a one-month continuous GNOME operation has not yet yielded a corresponding indication. However, the measurement allows the formulation of constraints on the characteristics of dark matter, as the researchers report in the journal Nature Physics.
