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

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 ...

What new methods can be developed in the search for extraterrestrial intelligence (SETI)? This is what a recent white paper ...

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.

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 ...

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 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 ...

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 ...

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 ...

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