查询词典 cosmic rays

Along the galactic plane, energetic cosmic rays collide with gas and dust to produce the diffuse gamma-ray glow.

Meanwhile Pierre Colin of the Max Planck Institute for Physics in Munich and his colleagues reckon that the shadow of the moon could be used to help work out whether the abundance of positrons actually does come from annihilating dark matter, using telescopes that look for Cherenkov radiation —flashes of light in the sky—that are created when cosmic rays, in the form of high-energy electrons and positrons, hit the upper atmosphere.

同时，在慕尼黑的马普物理研究所的皮埃尔·科林和他的同事们指出：可以用望远镜观测月球阴影下的切伦科夫辐射现象来判断大量的正电子是否的确来自湮灭的暗物质。切伦科夫辐射现象，是指带有高能量的电子和正电子的宇宙射线，撞击外层大气层时在天空中产生的闪光现象。
