This technique of looking for the decay products of WIMP annihilation is called indirect, as opposed to direct searches which look for dark matter interacting within a contained, instrumented volume. Solar WIMP searches are more sensitive to spin -dependent WIMP models than many direct searches, because the Sun is made of lighter elements than ...
Such a new view into the cosmos could give important clues in the search for dark matter and other astrophysical phenomena. After two years of integrated operation as part of IceCube, [1] the AMANDA counting house (in the Martin A. Pomerantz Observatory) was decommissioned in July and August 2009.
Astronomical searches for gravitational microlensing in the Milky Way found at most only a small fraction of the dark matter may be in dark, compact, conventional objects (MACHOs, etc.); the excluded range of object masses is from half the Earth's mass up to 30 solar masses, which covers nearly all the plausible candidates.
Dark matter is called ‘dark’ because it’s invisible to us and does not measurably interact with anything other than gravity. It could be interspersed between the atoms that make up the Earth ...
Dark matter may not give off any light or radiation, but we might be able to watch it smash into atoms here on Earth. Dark matter makes up 85% of all matter in the Universe, but astronomers have ...
Dark matter is a mysterious, invisible substance makes up more than 80 percent of all matter in the universe Science has found its first candidate for a dark-matter detector. It’s a really old rock
The South Pole Telescope (SPT) is a 10-metre (390 in) diameter telescope located at the Amundsen–Scott South Pole Station, Antarctica.The telescope is designed for observations in the microwave, millimeter-wave, and submillimeter-wave regions of the electromagnetic spectrum, with the particular design goal of measuring the faint, diffuse emission from the cosmic microwave background (CMB).

“But the dark matter particle has not been found, even though people looked in all the places where they expected to find it. This is not to say dark matter is not a particle, or that it’s for ...
