dark matter

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.

Berkeley Lab is leading the construction of a mile-deep experiment that seeks to solve a science mystery.

New experiments will help astronomers uncover the sources that helped make the universe transparent.

Scientists furthered studies of the Higgs boson, neutrinos, dark matter, dark energy and cosmic inflation and continued the search for undiscovered particles, forces and principles.

Theorists think dark matter was forged in the hot aftermath of the Big Bang.
