One of the most abundant iron-containing minerals on Earth, and also the oldest known magnetic material, is magnetite, Fe3O4. Magnetite has applications in many fields, such as the study of paleomagnetism—magnetism in rocks ...
For several years, astronomers and cosmologists have theorized about the existence of an additional planet with a mass 10 times greater than that of Earth, situated in the outermost regions of the solar system. This hypothetical ...
The hypothetical Planet Nine, assumed to be lurking somewhere in the outskirts of our solar system, may not be a planet at all. A new study, published September 24 on the arXiv pre-print server, suggests that the mysterious ...
Multimodal microscopy can combine complementary nanoscale imaging techniques to extract comprehensive information on the chemical, structural and functional aspects of heterogenous samples. X-ray microscopy can achieve high-resolution ...
Recent advances in the observation of high-energy radiations, including X-rays and gamma-rays, have unveiled many high-energy aspects of the universe. To achieve a complete understanding of these radiations, however, researchers ...
In quantum materials based on transition metals, rare-earth and actinide elements, electronic states are characterized by electrons in orbitals d and f, combined with the solid's strong band formation. Until now, to estimate ...
At the heart of a far-off galaxy, a supermassive black hole appears to have had a case of the hiccups. Astronomers from MIT, Italy, the Czech Republic, and elsewhere have found that a previously quiet black hole, which sits ...

An international team of astronomers reports the detection of a rare eclipsing Be/X-ray binary system as part of the Swift Small Magellanic Cloud (SMC) Survey (S-CUBED). The finding was detailed in a research paper published ...
Indian astronomers have conducted long-term X-ray observations of a nearby ultra-fast rotating active star known as AB Doradus A. Results of the observational campaign, published February 29 on the pre-print server arXiv, ...
Using NASA's Chandra X-ray spacecraft, astronomers have inspected a potential super-star cluster, designated HSO BMHERICC J72.971176-69.391112, or H72.97−69.39 for short. The new observations resulted in the detection of ...
