An international team of astronomers has carried out multi-wavelength observations of a blazar known as TXS 1515–273; they detected very-high energy (VHE) gamma-ray emission from this source for the first time. The finding ...
Astronomers from the Chinese Academy of Sciences (CAS) and elsewhere report the detection of a new ultra-high energy (UHE) gamma-ray source in the Galactic plane. The newly identified source, designated LHAASO J0341+5258, ...
Using the Large High Altitude Air Shower Observatory (LHAASO), astronomers have performed a search for new high-energy gamma-ray sources. As a result, they have identified a new ultra-high energy gamma-ray source, which received ...
Physicists from across three continents report the first experimental evidence to explain the unusual electronic behavior behind the world's thinnest superconductor, a material with myriad applications because it conducts ...

Fiber-shaped supercapacitors are a desirable high-performance energy storage technology for wearable electronics. The traditional method for device fabrication is based on a multistep approach to construct energy devices, ...
Using the Suzaku satellite, astronomers have examined a very high energy (VHE) blazar known as PKS 2155−304. They found that the source exhibits an X-ray intraday variability, which could improve the understanding of its ...
