A new, extremely efficient source of terahertz radiation has been developed at TU Wien (Vienna): Lasers turn air into plasma, thereby producing terahertz rays for many possible applications. Terahertz radiation is used for security checks at
It's a tough job to figure out which planets are potentially habitable, because we can only see so much detail in our telescopes.Details of an exoplanet's atmosphere and climate, for example, are mostly out of reach. A new study, however, uses
Material falling into a black hole casts X-rays out into space – and now, for the first time, ESA’s XMM-Newton X-ray observatory has used the reverberating echoes of this radiation to map the dynamic behavior and surroundings of a black hole itself.
Terahertz radiation is used for security checks at airports, for medical examinations and also for quality checks in industry. However, radiation in the terahertz range is extremely difficult to generate. Scientists at TU Wien have now succeeded in
An international team led by Argonne has visualized the elusive, ultrafast proton transfer process following the ionization of water. Understanding how ionizing radiation interacts with water — like in water-cooled nuclear reactors and other
An ultrathin coating developed by University of Wisconsin–Madison engineers upends a ubiquitous physics phenomenon of materials related to thermal radiation: The hotter an object gets, the brighter it glows. The new coating — engineered from
For the first time, physicists from the University of Würzburg have successfully converted electrical signals into photons and radiated them in specific directions using a low-footprint optical antenna that is only 800 nanometers in size.
