Powerful yet lonely: The distant quasar left alone in its group

Looking at the night sky with the naked eye, we can only see an infinitesimal part of what the Universe contains, and the largest part cannot even be "seen". Radio wavelengths have gifted us some of the most fascinating astronomical ...

3D-snapshots of nanoparticles

X-ray diffraction has been used for more than a hundred years to understand the structure of crystals or proteins—for instance, in 1952 the well-known double helix structure of the DNA that carries genetic information was ...

Electrocatalysis: Iron and cobalt oxyhydroxides examined

Very soon, we need to become fossil free, not only in the energy sector, but in industry as well. Hydrocarbons or other raw chemicals can be produced in principle using renewable energy and abundant molecules such as water ...

Mix of X-ray methods offers improved structure analysis

Sometimes scientists have to accept that a method they have used for years fails under certain conditions. Such a failure calls for a careful analysis of the shortcomings and their subsequent elimination. An international ...

Size of X-ray beams successfully evaluated with mathematics

X-ray fluorescence analysis allows elemental analysis in a variety of environments without destroying the sample. The smaller diameter of the X-ray microbeam, the more accurate the elemental distribution can be. Because X-ray ...

Examining an asteroid impact in slow motion

For the first time, researchers have recorded live and in atomic detail what happens to the material in an asteroid impact. The team of Falko Langenhorst from the University of Jena and Hanns-Peter Liermann from DESY simulated ...
