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 ...

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

A bizarre 'ultraluminous X-ray source' shines millions of times brighter than the sun, breaking a physical law called the Eddington limit, a new study finds. When you purchase through links on our ...

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 ...

Techniques that exploit the phase of X-rays, not just their absorption, have the potential to transform X-ray imaging in hospitals, reports Jude Dineley Improved imaging Marian Willner from the ...
