我们报告了Fermi大面积望远镜（LAT）在17个月的观测中寻找到0.1-10 GeV的磁星辐射。目前还没有发现任何已知磁星发射伽马射线的重要证据。迄今为止，它们在费米能量范围内持续发射的最严格上限估计在~ 10−12和10−10 erg s−1 cm−2之间，具体取决于源。我们还搜索了伽马射线脉冲和可能的爆发，也没有明显的发现。所得的上限支持在持续发射的磁星中，在低于几兆电子伏特的能量处存在一个截止点。他们还表明，可能需要对当前的强磁化脉冲星的外隙发射模型进行修订，在某些情况下，预测磁星的可探测GeV发射，其通量水平超过了这里使用费米- lat观测确定的上限。
We report on the search for 0.1–10 GeV emission from magnetars in 17 months of Fermi Large Area Telescope (LAT) observations. No significant evidence for gamma-ray emission from any of the currently known magnetars is found. The most stringent upper limits to date on their persistent emission in the Fermi energy range are estimated between ∼10−12and10−10 erg s−1 cm−2, depending on the source. We also searched for gamma-ray pulsations and possible outbursts, also with no significant detection. The upper limits derived support the presence of a cutoff at an energy below a few MeV in the persistent emission of magnetars. They also show the likely need for a revision of current models of outer-gap emission from strongly magnetized pulsars, which, in some realizations, predict detectable GeV emission from magnetars at flux levels exceeding the upper limits identified here using the Fermi-LAT observations.
