Gamma-ray spectroscopy is a vital analytical technique employed in identifying and quantifying radioactive nuclides, while artificial neural networks (ANNs) have emerged as robust computational tools ...

Cosmic rays, high-energy particles that travel through space, have puzzled scientists for decades. One particular feature of their energy spectrum—the “knee”—has long remained a mystery. Recent ...

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 ...

A team of engineers and scientists has shown for the first time that a hard-X-ray cavity can provide net X-ray gain, with X-ray pulses being circulated between crystal mirrors and amplified in the ...

The copper target was operated at voltages of 11 kV, 12 kV, 13 kV, and 14 kV for the electron source, and a 50 kV configuration using a molybdenum target was used as a representative example for the ...

A bright star visible without a telescope has puzzled X-ray astronomers for decades, producing high-energy radiation that no single-star model could fully explain. New research now traces the ...
