VLBA makes first direct distance measurement to magnetar

Astronomers using the National Science Foundation's Very Long Baseline Array (VLBA) have made the first direct geometric measurement of the distance to a magnetar within our Milky Way Galaxy—a measurement that could help ...

Self-imaging of a molecule by its own electrons

One of the long-standing goals of research on the light-induced dynamics of molecules is to observe time-dependent changes in the structure of molecules, which result from the absorption of light, as directly and unambiguously ...

Upgraded X-ray laser shows its soft side

The second phase of a major upgrade project is now online at the Linac Coherent Light Source (LCLS), the pioneering X-ray free-electron laser at Department of Energy's SLAC National Accelerator Laboratory. On September 12, ...

Attosecond pulses reveal electronic ripples in molecules

In the first experiment to take advantage of a new technology for producing powerful attosecond X-ray laser pulses, a research team led by scientists from the Department of Energy's SLAC National Accelerator Laboratory and ...

Physicists achieve tunable spin wave excitation

Physicists from MIPT and the Russian Quantum Center, joined by colleagues from Saratov State University and Michigan Technological University, have demonstrated new methods for controlling spin waves in nanostructured bismuth ...

Physicists nudge atoms within less than a trillionth of a second

Scientists from Regensburg and Zurich have found a fascinating way to push an atom with controlled forces so quickly that they can choreograph the motion of a single molecule within less than a trillionth of a second. The ...

Music goes terahertz

An international research team from Germany, Italy, and the U.K. has developed a key photonics component for the terahertz spectral range. By mixing electronic resonances in semiconductor nanostructures with the photon field ...
