超高能宇宙射线与GeV-TeV弥散Gamma-Ray通量

Ultra-High Energy Cosmic Rays and the GeV-TeV Diffuse Gamma-Ray Flux

Oleg E. Kalashev, Dmitry V. Semikoz, Guenter Sigl

摘要:

超高能宇宙射线质子在天体物理物体中加速后,在宇宙微波和红外背景中传播时会产生次级电磁级联。我们表明,这样的级联可以贡献~1%和~50%的GeV-TeV的扩散光子通量测量的EGRET实验。GLAST卫星应该有很好的机会发现这种通量。

英文摘要:

Ultra-high energy cosmic ray protons accelerated in astrophysical objects produce secondary electromagnetic cascades during propagation in the cosmic microwave and infrared backgrounds. We show that such cascades can contribute between ~1% and ~50% of the GeV-TeV diffuse photon flux measured by the EGRET experiment. The GLAST satellite should have a good chance to discover this flux.
