XMM-Newton reveals light 'echo' around supermassive black hole
Jun 05, 2012 (ESA)
Astronomers studying the galaxy NGC 4151 with ESA's XMM-Newton space observatory have detected X-rays emitted and then reflected by ionised iron atoms very clos...
McGill researcher helps NASA open a new window on the universe
May 31, 2012 (SPX)
NASA is making final preparations to launch its Nuclear Spectroscopic Telescope Array, NuSTAR. The mission, which will use X-ray vision to hunt for buried black...
NASA readies 'black hole hunter' mission
May 30, 2012 (AFP)
The US space agency said Wednesday it is preparing to launch next month a sophisticated orbiting telescope that will use high energy X-ray vision to hunt for bl...
Exotic particles, chilled and trapped, form giant matter wave
May 29, 2012 (SPX)
Physicists have trapped and cooled exotic particles called excitons so effectively that they condensed and cohered to form a giant matter wave. This feat will a...
The Older We Get, The Less We Know Cosmologically
May 25, 2012 (SPX)
The universe is a marvelously complex place, filled with galaxies and larger-scale structures that have evolved over its 13.7-billion-year history. Those began ...
Efficient and tunable interface for quantum networks
May 24, 2012 (SPX)
Quantum technologies promise to redefine the landscape of information processing and communication. We already live in an information age, in which vast amounts...
Elusive quasiparticles realized
May 24, 2012 (SPX)
Ultracold quantum gases are an ideal experimental model system to simulate physical phenomena in condensed matter. In these gases, many-body states can be reali...
Timely discovery: Physics research sheds new light on quantum dynamics
May 19, 2012 (SPX)
Kansas State University physicists and an international team of collaborators have made a breakthrough that improves understanding of matter-light interactions....
Fuel for the black hole
May 19, 2012 (SPX)
An international research team led by Gerd Weigelt from the Max-Planck-Institut fur Radioastronomie in Bonn reports on high-resolution studies of an active gala...
Three-Telescope Interferometry Allows Astrophysicists To Observe How Black Holes Are Fueled
May 19, 2012 (SPX)
By combining the light of three powerful infrared telescopes, an international research team has observed the active accretion phase of a supermassive black hol...
Black Holes Turn Up the Heat for the Universe
May 17, 2012 (SPX)
So far, astrophysicists thought that super-massive black holes can only influence their immediate surroundings. A collaboration of scientists at the Heidelberg ...
Watching an electron being born
May 16, 2012 (SPX)
A strong laser beam can remove an electron from an atom - a process which takes place almost instantly. At the Vienna University of Technology, this phenomenon ...
You can't play nano-billiards on a bumpy table
May 16, 2012 (SPX)
There's nothing worse than a shonky pool table with an unseen groove or bump that sends your shot off course: a new study has found that the same goes at the na...
Massive black holes halt star birth in distant galaxies
May 10, 2012 (SPX)
Astronomers, using the European Space Agency's (ESA) Herschel Space Observatory, have shown that the number of stars that form during the early lives of galaxie...
Queen's scientists discover black hole ripping apart star
May 09, 2012 (SPX)
Astronomers from Queen's University Belfast have gathered the most direct evidence yet of a supermassive black hole shredding a star that wandered too close. Th...
Atomic-scale visualization of electron pairing in iron superconductors
May 08, 2012 (SPX)
By measuring how strongly electrons are bound together to form Cooper pairs in an iron-based superconductor, scientists at the U.S. Department of Energy's (DOE)...
NASA's Chandra Sees Remarkable Outburst From Old Black Hole
May 03, 2012 (SPX)
An extraordinary outburst produced by a black hole in a nearby galaxy has provided direct evidence for a population of old, volatile stellar black holes. The di...
Old Star, New Trick
May 03, 2012 (SPX)
The Big Bang produced lots of hydrogen and helium and a smidgen of lithium. All heavier elements found on the periodic table have been produced by stars over th...
Researchers from the University of Zurich discover new particle at CERN
May 02, 2012 (SPX)
Physicists from the University of Zurich have discovered a previously unknown particle composed of three quarks in the Large Hadron Collider (LHC) particle acce...
Redefining time
May 01, 2012 (SPX)
Atomic clocks based on the oscillations of a cesium atom keep amazingly steady time and also define the precise length of a second. But cesium clocks are no lon...
