The Baryon Oscillation Spectroscopic Survey  - BOSS - is the largest component of the third Sloan Digital Sky Survey (SDSS-III) and pioneered the use of quasars to map density variations in intergalactic gas at high redshifts, tracing the structure of the young universe.

Ion Beams Mean a Quantum Leap for Color-Center Qubits Achieving the immense promise of quantum computing requires new developments at every level, including the computing hardware itself. A Lawrence Berkeley National Laboratory (Berkeley Lab)-led international team of researchers has discovered a way to use ion beams to create long strings of “color center” qubits in diamond. Their work is detailed in the journal Applied P...

Date Time Applying Quantum Computing to a Particle Process An ATLAS particle collision event display from 2018, showing the spray of particles (orange lines) emanating from the collision of protons, and the detector readout (squares and rectangles). (Credit: ATLAS collaboration) A team of researchers at Lawrence Berkeley National Laboratory (Berkeley Lab) used a quantum computer to successfully simulate an aspect of particle collisions that is typically neglected in high-energy physics experime...

Ideas, Inventions And Innovations Study: X-Rays Surrounding ‘Magnificent 7’ May Be Traces of Sought-After Particle Researchers say they may have found proof of theorized axions, and possibly dark matter, around group of neutron stars. An artistic rendering of the XMM-Newton (X-ray Multi-Mirror Mission) space telescope. A study of archival data from the XMM-Newton and the Chandra X-ray space telescopes found evidence of high levels of X-ray emission from the nearby Magnificent Seven neutr...

A new study, led by a theoretical physicist at Berkeley Lab, suggests that never-before-observed particles called axions may be the source of unexplained, high-energy X-ray emissions surrounding a group of neutron stars.
