Using NASA's Fermi spacecraft, Chinese astronomers have investigated the variability and spectral behavior of gamma-ray flares in a distant blazar known as 3C 279. Results of the study, presented in a paper published in the ...
A scientist from Tokyo Metropolitan University has shown that large gamma-ray-emitting bubbles around the center of the Milky Way were produced by fast, outward-blowing winds and an associated "reverse shock." Numerical simulations ...

The cosmic optical background (COB) is the visible light emitted by all sources outside of the Milky Way. This faint glow of light, which can only be observed using very precise and sophisticated telescopes, could help astrophysics ...
Gamma rays can cause serious damage to the human body. Therefore, it is very important to develop gamma-ray shielding materials with excellent radiation shielding properties. To reach this goal, scientists in China invented ...
