dark matter

The Dark Energy Survey collaboration has created the largest ever maps of the distribution and shapes of galaxies, tracing both ordinary and dark matter in the universe out to a distance of over 7 billion light years. The analysis, which includes the first three years of data from the survey, is consistent with predictions from the current best model of the universe, the standard cosmological model. Nevertheless, there remain hints from DES and other experiments that matter in the current universe is a few percent less clumpy than predicted.

From EIN Presswire, May 14, 2021; LBNL’s LArPix experiment result is a leap forward in how to detect and record signals in liquid argon time projection chambers (LArTPCs), a technology of choice for future neutrino and dark matter experiments such as Fermilab’s DUNE.

From Forbes, May 14, 2021: Fermilab senior scientist Don Lincoln discusses measuring the size of neutron stars and the result of a measurement showing that the centers of neutron stars are stiff and not squishy.

From Sanford Lab, May 10, 2021: Activities at the Sanford Underground Research Facility will have significant benefits for the state of South Dakota over the next decade.

From Forbes, April 29, 2021: Don Lincoln discusses a possible model of dark matter called a WIMP, short for weakly interacting massive particle.
