Asteroids Pound Radio Wave-Emitting Tiny Star

Scientists using CSIRO's Parkes telescope and another telescope in South Africa have found evidence that a tiny star called PSR J0738-4042 is being pounded by asteroids — large lumps of rock from space.

Gas Clouds Dim X-ray Signals from Active Galaxies

Picture a single cloud large enough to span the solar system from the sun to beyond Pluto's orbit. Now imagine many such clouds orbiting in a vast ring at the heart of a distant galaxy, occasionally dimming the X-ray light produced by the galaxy's monster black hole.

Astrophysicists Unravel How Stars Blow up in Supernova Explosions

For the first time, an international team of astrophysicists, including Lawrence Livermore National Laboratory scientists, have unraveled how stars blow up in supernova explosions.

Researchers Lay Groundwork for Understanding Role of Quantum Physics in Photosynthetic Processes

Biophotonic Solutions Inc. (BSI), the world leader in automated laser pulse compression, announces that its "MIIPS" laser pulse characterization, shaping, and compression technology was used in an advanced laser microscopy setup created by researchers at ICFO -- the Institute of Photonic Sciences -- in Barcelona, Spain, to study photosynthesis at the level of single molecules.

New Approach for Fabricating Lateral Spin Valves Using Ion Beams

Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have tested a new approach to fabricating spin valves. Using ion beams, the researchers have succeeded in structuring an iron aluminium alloy in such a way as to subdivide the material into individually magnetizable regions at the nanometer scale.

Leeds Quantum Cascade Terahertz Laser Sets New World Record in Output Power

A paper in the Institution of Engineering and Technology's (IET) journal Electronics Letters reports that the Leeds team has exceeded a 1 Watt output power from a quantum cascade terahertz laser.

Disrupted Star May Not Have Been a Rare Helium Star

Enrico Ramirez-Ruiz uses computer simulations to explore the universe's most violent events, so when the first detailed observations of a star being ripped apart by a black hole were reported in 2012 (Gezari et al., Nature), he was eager to compare the data with his simulations. He was also highly skeptical of one of the published conclusions: that the disrupted star was a rare helium star.

Observations of Exoplanets Not Good Enough to Draw Conclusions

Imagine someone spent months researching new cities to call home using low-resolution images of unidentified skylines. The pictures were taken from several miles away with a camera intended for portraits, and at sunset. From these fuzzy snapshots, that person claims to know the city's air quality, the appearance of its buildings, and how often it rains.

Rotation Rate of Galaxy Precisely Measured Based on Clock-Like Movement of its Stars

Using the sharp-eyed NASA Hubble Space Telescope, astronomers have for the first time precisely measured the rotation rate of a galaxy based on the clock-like movement of its stars.

Quantum Physics Ideas Put Modern Mathematical Ideas in a Natural Context

Galileo mused that in order to understand the universe, we must first understand the language that it is written in. That language? Mathematics. But, if we look to the universe first we can see the ways it has inspired new approaches to even the purest mathematics. Using ideas from quantum field theory, elementary particle physics and string theory we are able to solve deep problems in incredible ways.

Fast-Moving, Jet-Producing Pulsar Escapes From Supernova Remnant

NASA's Chandra X-ray Observatory has seen a fast-moving pulsar escaping from a supernova remnant while spewing out a record-breaking jet – the longest of any object in the Milky Way galaxy -- of high-energy particles.

Einstein Accepts Model of an Expanding Universe Only in 1931

Until 1931, physicist Albert Einstein believed that the universe was static. An urban legend attributes this change of perspective to when American astronomer Edwin Hubble showed Einstein his observations of redshift in the light emitted by far away nebulae—today known as galaxies. But the reality is more complex.

Researchers Discover Association of Gas-Rich Galaxies near the Infancy of Cosmic Time

Squinting close to the beginning of time, Dominik Riechers, Cornell assistant professor of astronomy, has discovered an association of gas-rich galaxies near the infancy of cosmic time. It’s an early epoch – some 12.7 billion years ago – telling a tale that revolves around an exceptionally dusty galaxy called AzTEC-3.

Larry Smarr First Honoree of Golden Goose Awards

Larry Smarr, a physicist whose work at the University of Illinois at Urbana-Champaign on calculating black hole collisions led him to champion a federal commitment to dramatically enhance U.S. computing power – which in turn led to the development of NCSA Mosaic, the precursor to web browsers – was named today as the first 2014 recipient of the Golden Goose Award.

JQI Researchers Explore One New Area of Nuclear-Atomic Overlap for Isotope Thorium 229

More than 99.9% of the mass of any atom is concentrated into a quadrillionth of its volume, the part occupied by the nucleus. Unimaginably small, dense and energetic, atomic nuclei are governed by laws quite distinct from those that regulate atomic electrons, which constitute the outer part of atoms and which are immediately responsible for light, chemistry and thus life.
