Astronomers have traced a mysterious blast of X-rays to a star that, like a cosmic action hero, just refused to die.

It provides an extremely high precision of about 1.2 x 10-4 at a photon energy of around 18.6 keV. Compared to conventional spectrometers, it achieves a signal strength that is four to 22 times ...

High-energy X-rays leave a trace of destruction in bone collagen. ScienceDaily . Retrieved June 2, 2025 from www.sciencedaily.com / releases / 2022 / 12 / 221222101006.htm ...

A distant galaxy cluster has turned into a giant particle accelerator, spinning electrons over vast distances at high speeds. IE 11 is not supported.

A distant cluster of galaxies is wrapped in a vast halo of high-energy particles that could be the work of supermassive black ...

China is set to unveil its High-Energy Photon Source (HEPS) that will transform scientific research with high-energy X-rays. With an investment of $665 million, ...

When that happens, the electron gives the photon part of its energy, which ramps low-energy infrared light up to the high-energy x-rays and gamma rays that light up the black hole’s jets.

High-energy clinical X-ray radiotherapy systems are typically based on a room-temperature RF linac that accelerates electron beams to the MeV level. These electrons then irradiate a target that ...

Contact: Barbara K. Kennedy [email protected] 814-863-4682 Penn State NASA’s Chandra X-ray Observatory has detected, for the first time in X rays, a stellar fingerprint known as a P Cygni profi… ...

"The high-energy photons from the X-ray light trigger a cascade of electron excitations. Ionization of calcium and phosphorus in the mineral then damages proteins like collagen in bone," Sauer says.

NASA's NuSTAR telescope has spotted patches of high-energy X-rays radiation across the sun's surface that could explain why the star's atmosphere is mysteriously hot.

A team of medical researchers at Charité-Universitätsmedizin has analyzed damage by focused high energetic X-rays in bone samples from fish and mammals at BESSY II. With a combination of ...
