According to theoretical predictions, axion dark matter could be converted into radio frequency electromagnetic radiation when it approaches the strong magnetic fields that surround neutron stars. This radio signature, which ...
For nearly a century, scientists have worked to unravel the mystery of dark matter—an elusive substance that spreads through the universe and likely makes up much of its mass, but has so far proven impossible to detect ...
