Chandra Discovers Extraordinary Ribbon of Hot Gas Trailing Behind Galaxy

An extraordinary ribbon of hot gas trailing behind a galaxy like a tail has been discovered using data from NASA's Chandra X-ray Observatory. This ribbon, or X-ray tail, is likely due to gas stripped from the galaxy as it moves through a vast cloud of hot intergalactic gas. With a length of at least 250,000 light years, it is likely the largest of such a tail ever detected.

PPPL Scientists Celebrate First Plasma of Wendelstein 7-X Stellarator

Scientists from the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) have reason to celebrate the first plasma of the Wendelstein 7-X (W7-X) stellarator at the Max Planck Institute in Greifswald, Germany earlier this month. The Laboratory has designed and contributed major components to the device and is collaborating on research. Three PPPL physicists attended the December 10 event.

Newly Upgraded Jefferson Lab Accelerator Delivers Full-Energy 12 GeV Electron Beam

The newly upgraded accelerator at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility has delivered full-energy electrons as part of commissioning activities for the ongoing 12 GeV Upgrade project. At 4:20 p.m. on Monday, Dec. 14, operators of the Continuous Electron Beam Accelerator Facility (CEBAF) delivered the first batch of 12 GeV electrons (12.065 GeV) to its newest experimental hall complex, Hall D.

Synthetic Aperture Microwave Imaging System Could Help Shed Light on Fusion Experiments

A system of antennas similar to those that astrophysicists use to study radio emissions from stars and galaxies will help shed light on fusion experiments at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL). Called Synthetic Aperture Microwave Imaging (SAMI), the system aims to provide highly precise time and spatial resolution measurements of the density of current at the edge of fusion plasmas in the National Spherical Torus Experiment-Upgrade (NSTX-U) -- the Laboratory's newly upgraded flagship facility that is set to embark on compelling new research programs.

Pure Spin Current Could Help Detect Magnetic Fluctuations

Electrons have two degrees of freedom, or attributes: charge and spin. With the development of microfabrication technology in recent years, through the active combination of these two attributes, it has become possible to create devices that are head and shoulders above electronics of the past.

Phonon and Photon Share Common Properties

A research group at Osaka University has succeeded in observing at the intended timing two-phonon quantum interference by using two cold calcium ions in ion traps, which spatially confine charged particles. A phonon is a unit of vibrational energy that arises from oscillating particles within crystals. Two-particle quantum interference experiments using two photons or atoms have been previously reported, but this group’s achievement is the world’s first observation using two phonons.

Astrophysicists Obtain Precise Measurements for Orbiting Object in Einstein’s Cross Quasar

Spanish astrophysicists obtain precise measurements for an object orbiting a black hole five billion lightyears away. This is like detecting the ridges of a one euro coin located 100,000 kilometres away.

Material Rotating Around Young Protostar Could Have Dragged in Twisted Magnetic Fields

Using new images that show unprecedented detail, scientists have found that material rotating around a very young protostar probably has dragged in and twisted magnetic fields from the larger area surrounding the star. The discovery, made with the National Science Foundation's Karl G. Jansky Very Large Array (VLA) radio telescope, has important implications for how dusty disks -- the raw material for planet formation -- grow around young stars.

Japanese Scientists Unlock Mystery Behind Auroral Breakup

Auroras are dimly present throughout the night in polar regions, but sometimes these lights explode in brightness. Now Japanese scientists have unlocked the mystery behind this spectacle, known as auroral breakup.

Black Holes Could Swell to 50 Billion Times the Mass of the Sun

Black holes at the heart of galaxies could swell to 50 billion times the mass of the sun before losing the discs of gas they rely on to sustain themselves, according to research at the University of Leicester.
