Shape of Spacetime Determined from Perpetual Ringing Caused By Quantum Fluctuations

As the universe expands, it is continually subjected to energy shifts, or "quantum fluctuations," that send out little pulses of "sound" into the fabric of spacetime. In fact, the universe is thought to have sprung from just such an energy shift.

AMS Detector Provides Most Precise Measurement of Cosmic Ray Positron Flux

The following is adapted from a press release issued today by CERN, the European Organization for Nuclear Research. Samuel Ting, the Thomas Dudley Cabot Professor of Physics at MIT and the spokesman for the international team of researchers running the Alpha Magnetic Spectrometer, also announced these results via webcast.

Excess of Positrons in Cosmic Ray Flux Observed by Alpha Magnetic Spectrometer

The international team running the Alpha Magnetic Spectrometer (AMS1) today announced the first results in its search for dark matter. The results, presented by AMS spokesperson Professor Samuel Ting in a seminar at CERN2, are to be published in the journal Physical Review Letters. They report the observation of an excess of positrons in the cosmic ray flux.

New Chandra Data Provides First Detection of X-Ray Emission from Young Stars outside Milky Way Galaxy

The Small Magellanic Cloud (SMC) is one of the Milky Way's closest galactic neighbors. Even though it is a small, or so-called dwarf galaxy, the SMC is so bright that it is visible to the unaided eye from the Southern Hemisphere and near the equator. Many navigators, including Ferdinand Magellan who lends his name to the SMC, used it to help find their way across the oceans.

Highly Star-Forming Green Pea Galaxies May Be Leaking Ionizing Radiation

The rare Green Pea galaxies discovered by the general public in 2007 could help confirm astronomers' understanding of reionization, a pivotal stage in the evolution of the early universe, say University of Michigan researchers.

Precise Measurement from Alpha Magnetic Spectrometer May Provide First Glimpse into Dark Matter

The first published results from the Alpha Magnetic Spectrometer (AMS), a major physics experiment operating on the International Space Station, were announced today by the AMS collaboration spokesman, Nobel Laureate Samuel Ting.

Researchers Utilize Terahertz Flashes to Investigate Light Tsunamis in a Superconductor

In their latest experiment, Prof. Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter at the Hamburg-based Center for Free-Electron Laser Science (CFEL) and Dr. Michael Gensch from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) investigated together with other colleagues from the HZDR, the United Kingdom, and Japan if and how superconductivity can be systematically controlled.

Stellar Spiral Arms in Disk Galaxies Not Transient, but Self-Perpetuating, Persistent and Long Lived

As the shapes of galaxies go, the spiral disk — with its characteristic pinwheel profile — is by far the most pedestrian.
