An international team of researchers has found evidence that suggests the Laser Interferometer Space Antenna (LISA) should be able to "see" ultralight bosons if they exist. In their paper published in the journal Nature Astronomy, ...
This photograph, taken a short hike from the Geographic South Pole in Antarctica, shows some of the antennas comprising the Super Dual Auroral Radar Network (SuperDARN) array. They are visible here as the chain of antennas ...
