Article describes simulation of mechanism that eliminates sawtooth instabilities in fusion plasmas.
Researchers have developed a microscopic "trampoline" that can absorb microwave energy and bounce it into laser light -- a crucial step for sending quantum signals over long distances.
Latest calculation based on how subatomic muons interact with all known particles comes out just in time for comparison with precision measurements at new 'Muon g-2' experiment.
An international team of scientists that includes UC Riverside physicist Hai-Bo Yu has imposed conditions on how dark matter may interact with ordinary matter. In the search for direct detection of dark matter, the experimental focus has been on WIMPs, or weakly interacting massive particles, the hypothetical particles thought to make up dark matter. But the research team invokes a different theory to challenge the WIMP paradigm: the self-interacting dark matter model, or SIDM.
The VERITAS array has confirmed the detection of high-energy gamma rays from the vicinity of a supermassive black hole located in a distant galaxy, TXS 0506+056. While these detections are relatively common for VERITAS, this black hole is potentially the first known astrophysical source of high-energy cosmic neutrinos, a type of ghostly subatomic particle that can be made at astrophysical sources of ultra-high energy cosmic rays.
Researchers help to resolve a more than century-old riddle about what sends subatomic particles such as neutrinos and cosmic rays speeding through the universe.
For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich, provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
An international team of scientists, with key contributions from researchers at the University of Maryland, has found the first evidence of a source of high-energy cosmic neutrinos, ghostly subatomic particles that travel to Earth unhindered for billions of light years from the most extreme environments in the universe.
In a global observation campaign, scientist have for the first time located a source of high-energy cosmic neutrinos, ghostly elementary particles that travel billions of light years through the universe, flying unaffected through stars, planets and entire galaxies. The campaign was triggered by a single neutrino that had been recorded by the IceCube neutrino telescope at the South Pole. Scientists from the 18 different observatories involved are presenting their findings in the journal Science.
Three professors at The University of Alabama are part of an international team of scientists who found evidence of the source of tiny cosmic particles, known as neutrinos, a discovery that opens the door to using these particles to observe the universe.
