Sterile Neutrinos Remain Elusive
2014-10-06 03:49:53

Brookhaven National Laboratory The Daya Bay Collaboration, an international group of scientists studying the subtle transformations of subatomic particles called neutrinos, is publishing its first results on the search for a so-called sterile neutrino, a possible new type of neutrino beyond the three known neutrino "flavors," or types. The existence of this elusive particle, if proven, would have a profound impact on our understanding of the universe, and could impact the design of future...

NASA's Cold Atom Laboratory Creates Atomic Dance
2014-09-29 03:24:59

Elizabeth Landau, NASA Like dancers in a chorus line, atoms' movements become synchronized when lowered to extremely cold temperatures. To study this bizarre phenomenon, called a Bose-Einstein condensate, researchers need to cool atoms to a temperature just above absolute zero – the point at which atoms have the least energy and are close to motionless. The goal of NASA's Cold Atom Laboratory (CAL) is to study ultra-cold quantum gases in a facility instrument developed for use on the...

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...

Andrew Gordon, DOE/SLAC National Accelerator Laboratory SLAC Experiment Reveals Mysterious Order in Liquid Helium An experiment at the Department of Energy's SLAC National Accelerator Laboratory revealed a well-organized 3-D grid of quantum "tornadoes" inside microscopic droplets of supercooled liquid helium – the first time this formation has been seen at such a tiny scale. The findings by an international research team provide new insight on the strange nanoscale traits of a...

Royal Astronomical Society A research team led by astronomers and astrophysicists at the University of Warwick have found that some of the Universe’s loneliest supernovae are likely created by the collisions of white dwarf stars into neutron stars. Dr Joseph Lyman from the University of Warwick is the lead researcher on the paper, which will appear in the journal Monthly Notices of the Royal Astronomical Society. "Our paper examines so-called 'calcium-rich' transients" says Dr Lyman....

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...

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...

redOrbit Staff & Wire Reports - Your Universe Online Using the ESA’s XMM-Newton and NASA’s Chandra X-ray Observatory, astronomers have located a mysterious X-ray signal that could be produced by sterile neutrinos – particles that are a potential candidate for the abundant and essentially invisible substance known as dark matter. [ What Is Dark Matter?: Podcast Interview With Dr. Matthew Walker ] Thanks to the two high-powered observatories, Dr. Esra Bulbul of the...

Astronomers Discover Bizarre Type Of Hybrid Star
2014-06-05 03:57:41

CU-Boulder In a discovery decades in the making, scientists have detected the first of a “theoretical” class of stars first proposed in 1975 by physicist Kip Thorne and astronomer Anna Żytkow. Thorne-Żytkow objects (TŻOs) are hybrids of red supergiant and neutron stars that superficially resemble normal red supergiants, such as Betelgeuse in the constellation Orion. They differ, however, in their distinct chemical signatures that result from unique activity in their stellar...

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....

White Dwarf
2004-10-19 04:45:43

White Dwarf -- A white dwarf is a a star supported by electron degeneracy. A star like our Sun will become a white dwarf when it has exhausted its nuclear fuel. Near the end of its nuclear burning stage, such a star goes through a red giant phase and then expels most of its outer material (creating a planetary nebula) until only the hot (T > 100,000 K) core remains, which then settles down to become a young white dwarf. A typical white dwarf is half as massive as the Sun, yet only...

Supernova -- A supernova is a star that increases its brightness drastically within a matter of days, making it appear as if a "new" star was born (hence "nova"). The "super" prefix distinguishes it from a mere nova, which also involves a star increasing in brightness, though to a lesser extent and through a much different mechanism. Astronomers have classified supernovae in several classes, according to the lines of different elements that appear in their spectra. The first...

Strange Matter -- Strange matter (also known as quark matter) is an ultra-dense phase of matter that is theorized to form inside particularly massive neutron stars (which are then known as "strange stars" or "quark stars"). It's theorized that when neutronium is put under sufficient pressure due to the gravitation of a large neutron star, the individual neutrons break down and their constituent quarks form strange matter. Strange matter is composed of strange quarks bound to each...

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...
