Latest Weakly interacting massive particles Stories
A dwarf galaxy recently discovered orbiting the Milky Way appears to be radiating gamma rays, and leading researchers from Brown and Carnegie Mellon universities hypothesize that it could be filled with particles of the mysterious substance known as dark matter.
A new study published in Physical Review Letters might explain why the universe did not collapse immediately after the Big Bang, which is something that scientists have been striving to understand.
For thirty long years, the scientific community has been searching for evidence that dark matter is comprised of exotic particles. A new study from Case Western Reserve University, however, suggests that researchers are looking in entirely the wrong direction.
The new PandaX facility, located deep underground in the southwestern Chinese province of Sichuan, hosts a large liquid-xenon detector designed to search for direct evidence of dark matter interactions with the nuclei of xenon and to observe 136Xe double-beta decay.
From the physics labs at Yale University to the bottom of a played-out gold mine in South Dakota, a new generation of dark matter experiments is ready to commence.
Physicist Richard Schnee hopes to find traces of dark matter by studying particles with low masses and interaction rates, some of which have never been probed before
A new study of gamma-ray light from the center of our galaxy makes the strongest case to date that some of this emission may arise from dark matter, an unknown substance making up most of the material universe.
Dark matter research, like all experiments involving particle and astrophysical detections, relies on sorting out the desired events (the source events) from the noise (the background events). Since the interactions occur at a quantum level, the statistical process of sorting through the data is laborious, but also, more importantly, relies on your ability to calibrate and understand the instrument.
Just three months into its operation, the Large Underground Xenon experiment is already the most sensitive dark matter detector in the world.
MIT physicists have proposed a new experiment to look for the elusive dark matter particle known as the 'A Prime' particle.
WIMP -- In astronomy, WIMPs, or weakly interacting massive particles, figure into one explanation of the dark matter problem. The particles are called "weakly interacting" because they seem not to have much interaction with normal matter (electrons, protons, and neutrons) other than gravitational attraction (thus "massive"). Assuming that there are Weakly Interacting Massive Particles, these particles would then fall out of equilibrium with the universe when they are non-relativistic....
