Some of the X-ray radiation circulating in the cavity is allowed to escape downstream, providing a beam of monochromatic and coherent X-ray pulses. They have called their system X-ray Free-Electron ...

TPU researchers have developed a mathematical model that accurately describes how Cherenkov radiation propagates in an exotic ...

Hamburg-based researchers have developed a system that generates better X-ray pulses at the European X-Ray Free-Electron ...

Artist’s impression of the powerful winds blowing from the bright X-ray source GX13+1. The X-rays are coming from a disc of hot matter, known as an accretion disc, that is gradually spiralling down to ...

Scientists at Brookhaven National Laboratory have developed a new AI-powered method called PFITRE that overcomes key limitations in nanoscale X-ray tomography, enabling clearer, more accurate 3D ...

Adriana Pálffy-Buß has been appointed to the new W2 professorship for Theoretical Quantum Information and Quantum Optics of the Cluster of Excellence ct.qmat - Complexity and Topology in Quantum ...

There are monstrous objects at the heart of every large galaxy — black holes that are millions or even billions of times more massive than the sun. And when these “supermassive” black holes start to ...
