3C 279周围的Gamma-ray晕:10月8日透过太阳看

Gamma-ray halo around 3C 279: looking through the Sun on the 8th of October

Malcolm Fairbairn, Timur Rashba, Sergey Troitsky

摘要:

我们讨论了如何可以用来提取非平凡的物理和天体物理信息,包括图像的角度大小时,它是显着小于实验的角分辨率的明亮源的高能伽马射线的太阳掩星。我们分析了EGRET数据,并讨论了其他仪器的前景。费米伽马射线太空望远镜将能够从每年10月8日的观测中限制3C~279周围可能存在的晕的大小。

英文摘要:

We discuss how the solar occultations of bright sources of energetic gamma rays can be used to extract non-trivial physical and astrophysical information, including the angular size of the image when it is significantly smaller than the experiment's angular resolution. We analyze the EGRET data and discuss prospects for other instruments. The Fermi Gamma Ray Space Telescope will be able to constrain the size of a possible halo around 3C~279 from observations it makes on the 8th of October each year.
