Studies Highlight Shapely Waves at Boundaries of Near-Earth Space

The universe overflows with repeating patterns. From the smallest cells to the largest galaxies, scientists are often rewarded by observing similar patterns in vastly different places.

Fermilab Generates Most Powerful High-Energy Particle Beam for Neutrino Experiments

A key element in a particle-accelerator-based neutrino experiment is the power of the beam that gives birth to neutrinos: The more particles you can pack into that beam, the better your chance to see neutrinos interact in your detector.

Astronomers Observe Super-Bright Supernova with Ultra-Long Gamma-Ray Burst

Astronomers from the Niels Bohr Institute have observed a super-bright supernova association with a very unusual long lasting gamma-ray burst.

Study Provides New Insights into Chemical Evolution of Milky Way Galaxy

Earth-like planets orbiting other stars in the Milky Way are three times more likely to have the same type of minerals as Earth than astronomers had previously thought. In fact, conditions for making the building blocks of Earth-like rocks are ubiquitous throughout the Milky Way.

Holographic Superconductor Could Be Realized in HL Gravity

Today theoretical physicists are facing the difficulty that General Relativity is not (pertubatively) renormalizable, and find that it is very hard to construct the quantum theory of gravity with LI. A possible solution is to break the LI in the ultraviolet (UV) region, so that the theory is renormalizable and unitary.

PanDA Workload Management System Evolves to Meet LHC's Full-Energy Collision Data

With the successful restart of the Large Hadron Collider (LHC), now operating at nearly twice its former collision energy, comes an enormous increase in the volume of data physicists must sift through to search for new discoveries. Thanks to planning and a pilot project funded by the offices of Advanced Scientific Computing Research and High-Energy Physics within the Department of Energy’s Office of Science, a remarkable data-management tool developed by physicists at DOE’s Brookhaven National Laboratory and the University of Texas at Arlington is evolving to meet the big-data challenge.

New Method to Solve General Relativity’s Gravitational N-Body Problem

Recent experiments have successfully tested Einstein's general theory of relativity in a variety of ways and to remarkable precision. These experiments included spacecraft Doppler tracking, planetary radar ranging, lunar and satellite laser ranging, as well as a number of dedicated gravitational experiments in space and many ground based efforts. How can computational models keep up with the ever improving accuracy of these missions?

Researchers Study Mutual Influence of Magnetic and Geometric Ordering in Crystalline Spinel

A team at HZB has carried out the first detailed study of how magnetic and geometric ordering mutually influence one another in crystalline samples of spinel. To achieve this, the group synthesized a series of mixed crystals with the chemical formula Ni1-xCuxCr2O4 in which the element nickel was successively replaced by copper. They discovered through neutron scattering experiments at BER II not only how the crystal structure changes, but also uncovered new magnetic phases. The results were published in Physical Review B.

Supercomputers Help Investigate Exotic Mesons

Quarks and antiquarks are the teeny, tiny building blocks with which all matter is built, binding together to form protons and neutrons in a process explained by quantum chromodynamics (QCD).
