Scientists Detect Brightest Flare Ever Observed from Sagittarius A* Black Hole

As black holes go, Sagittarius A* is relatively low-key. The black hole at the center of our galaxy emits very little energy for its size, giving off roughly as much energy as the sun, even though it is 4 billion times as massive.

Rotating Vortex Beams Offer New Possibilities for Electron Microscopy

Nowadays, electron microscopes are an essential tool, especially in the field of materials science. At TU Vienna, electron beams are being created that possess an inner rotation, similarly to a tornado. These "vortex beams" cannot only be used to display objects, but to investigate material-specific properties - with precision on a nanometer scale. A new breakthrough in research now allows scientists to produce much more intense vortex beams than ever before.

Quantum Cryptography Offers Security Protected by the Laws of Physics

Quantum cryptography is the ultimate secret message service. Research published 18 October in Physical Review Letters shows that it can counter even the ultimate paranoid scenario: when the equipment or even the operator is in the control of a malicious power.

Carbon-Rich Asteroids Contribute to Dark Material on Giant Asteroid Vesta

Like a Hollywood starlet constantly retouching her make-up, the giant asteroid Vesta is constantly stirring its outermost layer and presenting a young face. Data from NASA's Dawn mission show that a common form of weathering, which occurs on many airless bodies in the inner solar system like the Moon, does not age Vesta’s outermost layer.

Researchers Test Quantum Mechanical Entanglement with Rotating Photons

To this end, the researchers developed a new method for entangling single photons which gyrate in opposite directions. This result is a first step towards entangling and twisting even macroscopic, spatially separated objects in two different directions.

Scientists Generate Quantum Matter Having Crystal-Like Properties

Both high-valued diamond and low-prized graphite consist of exactly the same carbon atoms. The subtle but nevertheless important difference between the two materials is the geometrical configuration of their building blocks, with large consequences for their properties.

Astronomers Study Gamma Rays from Black Hole-Powered Galaxies

Astronomers using data from NASA's Fermi Gamma-ray Space Telescope have made the most accurate measurement of starlight in the universe and used it to establish the total amount of light from all of the stars that have ever shone, accomplishing a primary mission goal.

New Device Powered by Quantum Nonlocality Measures Wave-Particle Duality of Photons

What is light made of: waves or particles? This basic question has fascinated physicists since the early days of science. Quantum mechanics predicts that photons, particles of light, are both particles and waves simultaneously. Reporting in Science, physicists from the University of Bristol give a new demonstration of this wave-particle duality of photons, dubbed the 'one real mystery of quantum mechanics' by Nobel Prize laureate Richard Feynman.

Scientists Observe Distant, Super-Luminous Supernovae

The most-distant, super-luminous supernovae found to date have been observed by an international team, including Raymond Carlberg of the University of Toronto's Department of Astronomy & Astrophysics. The stellar explosions would have occurred at a time when the universe was much younger and probably soon after the Big Bang.

PM's Science Prize Awarded for Investigations into Dark Matter in Galaxies

The Australian Institute of Physics congratulates the winners of the Prime Minister's Prizes for Science, who received their awards at a dinner at Parliament House last night.

Quasars Illuminate Dark Galaxies

Most people think of galaxies as huge islands of stars, gas and dust that populate the universe in visual splendor. Theory, however, has predicted there are other types of galaxies that are devoid of stars and made predominately of dense gas. These "dark" galaxies would be unseen against the black backdrop of the universe.

Schrödinger’s Thought Experiment Quantum Theories Applied to Holy Books

Whenever I see angry mobs reacting to the destruction of religious books it makes me think of Schrödinger, iPads and how we should interpret fundamentalist religious teachings in the digital era.

Researchers Discover Super-Luminous Supernovae in the Early Universe

Supernovae are the brilliant, explosive deaths of stars. For a short time, these explosions can outshine an entire galaxy containing billions of stars.

Scientists Synthesize New Superconductors Based on Iron and Selenium

Physicists describe how they have synthesized a new material that belongs to the iron-selenide class of superconductors, called LixFe2Se2(NH3)y, in a paper about to be published in EPJ B. The work was carried out by Ernst-Wilhelm Scheidt from the University of Augsburg and colleagues. This material displays promising superconducting transition temperatures of 44 Kelvins (K) at ambient pressure, thus improving upon traditional copper-based high-temperature superconductors.
