Brendan M. Lynch, University of Kansas Astrophysicists believe that about 80 percent of the substance of our universe is made up of mysterious “dark matter” that can’t be perceived by human senses or scientific instruments. “Dark matter has not yet been detected in a lab. We infer about it from astronomical observations,” said Mikhail Medvedev, professor of physics and astronomy at the University of Kansas, who has just published breakthrough research on dark matter that...

Science China Press 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. The detector's central vessel was designed to accommodate a staged target volume increase from an initial 120 kg (stage I) to 0.5 t (stage II) and ultimately to a multi-ton scale. The technical design...

Yale University 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. The U.S. Department of Energy's Office of Science and the National Science Foundation recently gave the go-ahead to LUX-Zeplin (LZ), a key experiment in the hunt for dark matter, the invisible substance that may make up much of the universe. Daniel McKinsey, a professor of physics, leads a contingent of Yale...

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online All across the Universe high-energy charged particles – mostly protons, electrons, and hydrogen nuclei, though heavier nuclei also exist – are found racing in all directions. The source of these particles, collectively called cosmic rays, is masked by the interstellar magnetic field that bends their paths, making them nearly impossible to directly trace. Much progress has been made in narrowing down their origin in recent...

Science China Press The PandaX experiment of China, which is located in the deepest underground laboratory, has released its technical design report recently. The full article will appear in SCIENCE CHINA Physics, Mechanics & Astronomy. The Particle and Astrophysical Xenon (PandaX) collaboration was established in 2009 and mainly supported by the Ministry of Science and Technology, the Ministry of Education in China,the Natural Science Foundation of China,and Shanghai Jiao Tong...

Scientists Reformulate Their Knowledge Of Dark Matter
2014-07-04 09:21:15

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online For decades, the mystery of Dark Matter has been at the forefront of physics research. Since the 1930s, scientists have been aware that all of the mass that we can see – the stars, the dust, the planets, and black holes – makes up only 20% of the Universe. The rest, it seems, is made of some other form of matter; something different than the protons, neutrons, and electrons that we are most familiar with. There were many...

Syracuse University Plays Key Role In Search For Elusive Dark Matter
2014-04-11 13:31:00

By Rob Enslin, Syracuse University 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. The ongoing search for invisible dark matter is the subject of a recent article involving physicists from Syracuse University's College of Arts and Sciences. Research by Richard Schnee, assistant professor of physics, is referenced in Symmetry magazine, a joint publication of the...

Dark Matter Clues From The Center Of Our Galaxy

[ Watch the Video: Fermi Data Hints At New Dark Matter Clues ] Francis Reddym, NASA Goddard Space Flight Center 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. Using publicly available data from NASA's Fermi Gamma-ray Space Telescope, independent scientists at the Fermi National Accelerator Laboratory (Fermilab), the...

Dark Matter Results From LUX Confirmed After Recalibration - WIMPs Still Not Detected
2014-02-21 08:47:17

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online 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. Back in October the Large...

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....

Massive Compact Halo Object (MACHO) -- Massive compact halo objects, or MACHOs, are a type of astronomical body proposed as one possible explanation for the presence of dark matter in galactic halos. A MACHO is a small chunk of normal baryonic matter, far smaller than a star, which drifts through interstellar space unassociated with any solar system. Since MACHOs would not emit any light of their own, they would be very hard to detect. Recent work has suggested that MACHOs are not...

Cosmic Rays -- Cosmic Rays. Cosmic rays are energetic particles that are found in space and filter through our atmosphere. Cosmic rays have interested scientists for many different reasons. They come from all directions in space, and the origination of many of these cosmic rays is unknown. Cosmic rays were originally discovered because of the ionozation they produce in our atmosphere. Cosmic rays also have an extreme energy range of incident particles, which have allowed physicists to...
