我们赖以生存的地球无时无刻不在经受来自外太空中高能粒子的轰击，这些粒子包括各种原子核、正负电子、高能伽马射线和中微子等，它们统称为宇宙线。人类对宇宙线的观测和研究已经长达一个世纪。宇宙线曾经对基本粒子物理学科起到了非常重要的作用，人们从宇宙线中发现了一大批新粒子。宇宙线和物质的相互作用就像天然的对撞机，而其能量可以远远高于人造加速器的能量，给我们提供了丰富的关于物质基本结构及其相互作用规律的知识。...
VLA and XMM-Newton Observations of the SNR W41/TeV Gamma-Ray Source HESS J1834–087
W41 HESS
2014/12/23
The recently discovered extended TeV source HESS J1834-087 is associated with both a diffuse X-ray enhancement and a molecular cloud, projected at the center of an old radio supernova remnant, G23.3-0...
国家天文台研究员田文武与合作者Leahy教授使用美国甚大射电望远镜阵巡天的数据，将他们改进的中性氢吸收谱测距方法应用于有罕见甚高能伽玛辐射的复合体W51，研究了W51中各组成天体之间的几何关系，发现以前广为认可的高速中性氢（HI）云与超新星遗迹(SNR)W51C成协的关系并不存在，这直接动摇了W51中甚高能伽玛辐射起源于超新星遗迹与临近分子云相互作用的流行观点。该研究结果发表在国际著名期刊《天体物...

Cherenkov telescopes play a major role in the growth of the TeV Astronomy which, in 20 years, has reached the status of an important branch of Astrophysics, because of the observations of the violent,...
Fluctuation of TeV to EeV Energy Muons and Induced Muon Showers in Water
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/27
By using the integral method in the muon propagation through water, we calculate the range fluctuation of high and ultra high energy muons. Many authors divide all radiative processes into two parts, ...
Modeling TeV gamma-rays from LS 5039: An active OB star at the extreme
High Energy Astrophysical Phenomena (astro-ph.HE) Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/23
Perhaps the most extreme examples of "Active OB stars" are the subset of high-mass X-ray binaries -- consisting of an OB star plus compact companion -- that have recently been observed by Fermi and gr...
