Abstract:
Fri 28 Oct, 2016.

The "dark matter problem" is one of the longest-standing questions in astrophysics to date. For nearly a century, researchers have known that the amount of matter we can detect in large clusters of galaxies through its electromagnetic radiation is in disagreement with the amount of matter we can infer through its gravitational influence. Evidence for this "missing mass" can also be found in the outer regions of galactic rotation curves, in the severity of gravitational lensing around different classes of objects, and in the power spectrum of the Cosmic Microwave Background, measured by the Planck spacecraft. This latter result, coupled with the Lambda/Cold Dark Matter (ΛCDM) model of cosmology, suggests that nearly 85% of the mass in the universe is in the form of non-baryonic dark matter. Supersymmetric extensions to the standard model predict a class of particles, called Weakly-Interacting Massive Particles (or WIMPs) which, if discovered, could explain this hundred-year-old problem of "missing mass". Several direct detection efforts are currently underway, including the DarkSide experiment, housed at the Laboratori Nazionali del Gran Sasso (LNGS) in central Italy. Though no conclusive evidence for particulate dark matter has yet been published, if one of these direct detection experiments proves successful, we may finally begin to understand this elusive form of matter.

Notes and Changes:
Changed "G1, G,2, G3" to "1st gen., 2nd gen., 3rd gen." to avoid confusion with DOE classification. Added DEAP-3600 and removed DARWIN. Changed DS-20k start date from 2019 to 2021. Other small aesthetic changes.
