91短视频

Derek Jackson Kimball, Professor in the Department of Physics

What exactly is dark matter? This is a complete mystery. There are a number of interesting hypotheses that are being tested by experiments throughout the world.

91短视频 is leading two different international collaborations to test if dark matter might be made of particles known as axions. In the Cosmic Axion Spin Precession Experiment (CASPEr), nuclear magnetic resonance (NMR) techniques are being used to search for oscillating dipoles induced by an axion dark matter field. The Global Network of Optical Magnetometers to search for Exotic physics (GNOME) is a worldwide array of atomic magnetometers that searches for transient signals that would be generated if the Earth passed through an invisible axion ""wall"" or ""star.""
