Muon-Based Technology for Imaging Nuclear Fuel Debris Inside Fukushima Dai-Ichi Reactor

Toshiba Corporation and the International Research Institute for Nuclear Decommissioning (IRID) today announced the development of a muon[1]-based technology for imaging and mapping nuclear fuel debris inside the reactor pressure vessel (RPV) of the Fukushima Dai-ichi Nuclear Power Plant. The system was developed as the part of sub-project for “Development of Fuel Debris Sensing Technology for Nuclear Reactors” financed by the Agency for Natural Resources and Energy.

Simulation Proves Effect of Galactic Rocket Engine in Galaxy Collisions

Cosmic accidents are frequent occurrences in space: two or more disk galaxies collide and form elliptical systems. These contain regions in which the stars orbit the centre in precisely the opposite direction to what happens in the rest of the galaxy. Previous attempts to explain this assumed the colliding galaxies had a special relative orientation (“retrograde”). Athanasia Tsatsi, a doctoral student at the Max Planck Institute for Astronomy in Heidelberg, has now found a further possibility: the mass loss of the galaxies involved acts as a kind of huge rocket engine.

Muons in Stishovite Exist as Muoniums with a Captured Electron in Interstitial Positions

A research group led by Associate Professor Nobumasa Funamori, Department of Earth and Planetary Science, Graduate School of Science, University of Tokyo, along with research groups specialized in high-pressure Earth science and muon science, including the Institute of Materials Structure Science, jointly studied the condition of muons (µ+, mu particles) implanted in stishovite, a high-pressure phase of quartz, using the muon spin rotation method, and found that muons exist in interstitial positions in the form of muoniums with a captured electron.

Quantum Entanglement Among Individual Photon Pairs in a Squeezed Light Beam

In a recent study published in Physical Review Letters and highlighted by the magazine Science News, the research group led by ICREA Prof at ICFO Morgan Mitchell has detected, for the first time, entanglement among individual photon pairs in a beam of squeezed light.

High Altitude Water Cherenkov Observatory Begins Gathering Information on Cosmic Gamma Rays

In the shadow of Mexico’s tallest mountain, an array of 300 water-filled silver tanks is capturing the calling cards left by powerful visitors from our galaxy and beyond. The tanks are the most visible components of the High Altitude Water Cherenkov Observatory (HAWC), a one-of-its-kind facility designed to gather information about high-energy gamma rays entering the Earth’s atmosphere.

Dark Matter May Not Be Composed of Particles

When galaxy clusters collide, their dark matters pass through each other, with very little interaction. Deepening the mystery, a study by scientists at EPFL and the University of Edinburgh challenges the idea that dark matter is composed of particles.

Astronomers Identify Best Type Ia Supernovae for Measuring Cosmic Distances

The brilliant explosions of dead stars have been used for years to illuminate the far-flung reaches of our cosmos. The explosions, called Type Ia supernovae, allow astronomers to measure the distances to galaxies and measure the ever-increasing rate at which our universe is stretching apart.

Supercomputer JUQUEEN Helps Calculate Tiny Neutron-Proton Mass Difference

The fact that the neutron is slightly more massive than the proton is the reason why atomic nuclei have exactly those properties that make our world and ultimately our existence possible. Eighty years after the discovery of the neutron, a team of physicists from France, Germany, and Hungary headed by Zoltán Fodor, a researcher from Wuppertal, has finally calculated the tiny neutron-proton mass difference.

Strong Winds Blown By Supermassive Black Hole Can Disperse Gas Reservoir of Host Galaxy

Astronomers have found proof that the strong winds blown by a supermassive black hole are dispersing the gas reservoir of its host galaxy. The new finding relies on the observation of two phenomena in the same galaxy: a large-scale galactic outflow, seen by ESA's Herschel space observatory, and a black-hole driven wind at the galaxy's core, detected with the JAXA/NASA’s Suzaku X-ray observatory.

Dark Matter Interacts with Itself Much Lesser Than Previously Thought

Astronomers using observations from the NASA/ESA Hubble Space Telescope and NASA's Chandra X-ray Observatory have studied how dark matter in clusters of galaxies behaves when the clusters collide.
