Australian dark matter detector starts long-term hunt for mysterious particles

The Oscillating Resonant Group AxioN (ORGAN) experiment has began operations, and has completed the first search for axions, which are candidate particles for making up dark matter. While researchers have never observed dark matter directly before, the existence of the mysterious substance can be inferred based on a mismatch in the masses of galaxies and the estimates for how much they should weigh based on the number of stars in them. The experiment has been initiated after four years of research and development, and has come online almost at the same time as another effort to hunt down the elusive dark matter particles, the LUX-ZEPELIN dark matter detector.

Axions, OK.

Largely ruled out already, but still possible if they have masses very similar to those of neutrinos. Not smaller and not larger.
