dark matter

From Phys.org, Jan. 25, 2023: Researchers at Fermilab, Northwestern University and Stanford University recently demonstrated an entirely new method for searching for meV dark matter. The group is testing a hypothesis that when the rest energy of a dark photon matches the energy splitting of the two lowest cyclotron levels, the first state of the electron cyclotron will be excited.

From Big Think, Jan. 6, 2023: While astronomers debate the existence of dark matter, Don Lincoln breaks down a new paper published in Nature Astronomy that claims to debunk a key observation that strengthens the case that the Universe is full of unseen matter.

From Physics World, October 20, 2022: A new multiple-mirror imaging technique could greatly improve the performance of atom interferometers, making them more useful in applications ranging from dark matter detection to quality control in manufacturing. The technique was developed by researchers at SLAC and a possible use for this would be in the Matter-wave Atomic Gradiometer Interferometric Sensor, a 100-metre-long atom interferometer currently being installed at Fermilab.

From Coast to Coast with George Noory, August 17, 2022: Fermilab’s senior scientist Don Lincoln talks about his time working on the Tevatron at Fermilab and the LHC at CERN. Listen to find out more about the restart of the LHC and the big mysteries in astronomy regarding dark matter and how galaxies defy physics.

From Big Think, August 13, 2022: After decades of research, astronomers cannot explain how and why galaxies exist. Fermilab’s Don Lincoln discusses the hypothesis of dark matter as the undiscovered form of matter to explain this galactic mystery.

Dark matter is invisible; it’s everywhere; and it doesn’t interact with matter very often. The same is true for neutrinos. So are neutrinos dark matter? Neutrino physicist Kirsty Duffy and neutrino/dark matter researcher Asher Kaboth (Royal Holloway, University of London) break down the most likely dark matter candidates and where neutrinos fit into the mix.
