The XENON collaboration's search for dark matter.
Astronomical observations – such as the rotation velocities of galaxies and gravitational lensing – show that more than 80% of the matter in the universe remains invisible.
In November the Baryon Oscillation Spectroscopic Survey (BOSS) released its second major result of 2012, using 48,000 quasars with redshifts (z) up to 3.5 as backlights to map intergalactic hydrogen ...
By professional astronomy standards, the 2.5 m telescope at Apache Point Observatory is quite small. More than 50 research telescopes are larger and many are located at much better sites.
The XENON collaboration has announced results that provide no evidence for the existence of weakly interacting massive particles.
Towards new levels of sensitivity in detecting dark-matter particles.
Dark matter may constitute 83% of the particles in the universe, but so far there has been no direct observation of its presence in experiments.
The Nobel laureate on the discovery behind dark energy.
A report from a workshop to discuss directions in dark-matter research.
