This change was observed in extremely high-energy X-rays, which are incredibly hot, around a billion kelvin. The rays form when low-energy photons interact with hot material from the inner disk ...

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

The dual detection in both radio and high-energy X-rays provides a critical clue, helping astronomers refine theories about these mysterious objects and potentially uncover more examples, ...

Introduction THE photo-disintegration of atomic nuclei by high-energy X-rays is well known ; but there seems previously to have been no record of the production of radioactivity in animal tissues.

Phase imaging with high-energy x-rays. 17 Jun 2002. Conventional x-ray imaging methods detect how many x rays are absorbed as they pass through a sample. As objects get thicker it becomes necessary to ...

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 ...

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 ...

This process will produce high-energy X-rays that can penetrate deep into samples, revealing intricate details at the nanometer scale, a report in journal Nature said.

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 penetrate inhomogeneous samples up to a centimeter thick under real operating conditions. This avoids the challenges of FIB and TEM techniques while also providing a better ...

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

The ultrabright light produced by the photon source will address urgent needs for ultrabright, high-energy X-rays in cutting-edge research across various fields, including aerospace, energy ...
