SLAC Setting up Test Stand for LUX-ZEPLIN Dark Matter Experiment

Researchers have come a step closer to building one of the world’s best dark matter detectors: The U.S. Department of Energy (DOE) recently signed off on the conceptual design of the proposed LUX-ZEPLIN (LZ) experiment and gave the green light for the procurement of some of its components.

International Project to Find Direct Evidence of Gravitational Waves

An international project involving Cardiff University researchers, set up to find the first direct evidence of the existence of gravitational waves, will be officially inaugurated at a ceremony in the US today [19 May 2015].

Simulation Explains Collision Between Two Clusters Of Galaxies

Tom Broadhurst, the Ikerbasque researcher in the Department of Theoretical Physics of the UPV/EHU, together with Sandor Molnar of the National Taiwan University and visiting Ikerbasque researcher at the UPV/EHU in 2013, have conducted a simulation that explains the collision between two clusters of galaxies. Clusters of galaxies are the biggest objects that exist in the universe. They are collections of hundreds of thousands of galaxies pulled together by gravity.

Quantum Faucet Shows Fundamentally Different Behaviour

We all know intuitively that normal liquids flow more quickly as the channel containing them tightens. Think of a river flowing through narrow rapids.

Quantum Monte Carlo Calculations Used to Predict Magnetic Behavior in Metal Oxide Systems

The Science
Theoretical calculations were successfully used to predict magnetic properties of the complex electron behavior in metal oxide systems – combinations of metals such as iron, cobalt, nickel or copper with oxygen, which possess a wealth of useful properties. Enabled by high-performance computing, the magnetic couplings in model systems for copper-containing cuprate high-temperature superconductors were accurately calculated for the first time.

Astronomers Trace Stellar Migration of 3000 White Dwarfs

Astronomers using the NASA/ESA Hubble Space Telescope have, for the first time, collected a census of young white dwarf stars beginning their migration from the crowded centre of an ancient star cluster to its less populated outskirts. The new results challenge our ideas about how and when a star loses its mass near the end of its life.

‘Left-Handed’ Magnetic Field Could Be Linked to Absence of Cosmic Antimatter

The discovery of a ‘left-handed’ magnetic field that pervades the universe could help explain a long standing mystery – the absence of cosmic antimatter. A group of scientists, led by Prof Tanmay Vachaspati from Arizona State University in the United States, with collaborators at Washington University and Nagoya University, announce their result in Monthly Notices of the Royal Astronomical Society.

Astronomers Discover First Quadruple Quasar

Using the W.M. Keck observatory in Hawaii, a group of astronomers led by Joseph Hennawi of the Max Planck Institute for Astronomy have discovered the first quadruple quasar: four rare active black holes situated in close proximity to one another.

Researchers Observe New Rare Particle Decay

In an article published today in Nature, the CMS and LHCb collaborations describe the first observation of the very rare decay of the B0s particle into two muon particles.
