用Fermi-LAT探测太阳系天体的gamma-ray辐射
Search for gamma-ray emission from solar system bodies with Fermi-LAT
摘要：
FERMI-LAT正在以前所未有的灵敏度和角分辨率进行从30 MeV到$>$ 300 GeV的全天空伽马射线勘测。FERMI从第一周的数据采集开始就探测到了来自月球和太阳的高能伽马射线。这种辐射是由宇宙射线与这些物体相互作用产生的。类似地，一些伽马射线辐射可以通过与小行星和行星的相互作用产生。我们已经在前6个月的数据采集中搜索了这些看起来像发射的主要行星。我们在这里介绍搜索的情况。
英文摘要：
FERMI-LAT is performing an all-sky gamma-ray survey from 30 MeV to $>$300 GeV with unprecedented sensitivity and angular resolution. FERMI has detected high-energy gamma rays from the Moon and Sun since the first weeks of data taking. This emission is produced by interactions of cosmic rays with these objects. Similarly, some gamma ray emission can be produced by interactions with asteroids and planets. We have searched this emission looking major planets during the first 6 months of data taking. We present here the status of the search.
