A team of undergraduate students from the University of Hamburg built a simple detector to search for axions, which are leading candidates for dark matter. Despite working with limited resources, they established new experimental limits on axion properties.

Scientists have long been searching for dark matter, but it's not always necessary to have massive observatories or large international collaborations to make progress. A recent study shows that even small teams with creative approaches and institutional support can still contribute significantly to the field. A group of undergraduate students from the University of Hamburg designed and built a cavity detector to search for axions, which are among the leading candidates for dark matter.

The project was funded through a student research grant from the University of Hamburg's Hub for Crossdisciplinary Learning program. The team worked closely with researchers from the MADMAX experiment, a larger and more complex study that also searches for axions. Despite working with limited resources, the students were able to establish new experimental limits on axion properties.

The detector was built using existing facilities and equipment, and the team carefully tested and calibrated it before collecting data. Although they did not detect any signal that could be attributed to axions, their experiment still provides important new constraints on the properties of these particles.
