dark matter

A theory about gravity challenges our understanding of the universe.

Scientists at Fermilab and the University of Chicago are planning to search for hypothesized invisible particles using cutting-edge quantum sensor technology.

A NASA rocket experiment could use the Doppler effect to look for signs of dark matter in mysterious X-ray emissions from space.

The Heavy Photon Search at Jefferson Lab is looking for a hypothetical particle from a hidden “dark sector.”

The PICO experiment homes in on dark matter.

From Astronomy, May 4, 2017: Fermilab’s Dan Hooper sat down with Astronomy Editor-in-Chief Dave Eicher to discuss cutting-edge research into the unknowns of the universe.

From CERN Courier, April 13, 2017: It took decades for dark matter to enter the lexicon of particle physics. Today, explaining the nature and abundance of dark matter is one of the most pressing problems in the field. Fermilab and University of Chicago’s Dan Hooper and University of Amsterdam’s Gianfranco Bertone review the 80-year history.

We know which way the dark matter wind should blow. Now we just have to find it.

From Science, March 6, 2017: For more than a decade, multiple experiments have found an unexpected excess in the number of high-energy antielectrons, or positrons, in space. A team led by Fermilab’s Dan Hooper has shown that pulsars, not dark matter annihilation, can indeed produce most or all of the excess.

The PICO-60 dark matter bubble chamber experiment has produced a new dark matter limit after analysis of data from the most recent run.
