论文摘要
我们报告了使用档案Chandra和XMM-Newton观察进行的兔脉冲星脉冲状星云（PWN）的伽马射线PSR PSR J1418 $ - $ 6058的X射线研究。使用120 ks XMM-Newton数据进行的精制定时分析发现，在$ p \ of110 $ ms下的脉动很重要（$ p \ oft10^{ - 7} $），这与与费米大型面积望远镜（LAT）一起测量的脉动是一致的。在Chandra图像中，我们发现脉冲星周围的延长发射类似于年轻pwne中其他脉冲星周围的发射，这进一步主张PSR J1418 $ -6058和兔子PWN之间的关联。脉冲星的X射线光谱很难，与软γ脉冲星的X射线光谱相似。因此，PSR J1418 $ - $ 6058可能会添加到Soft-Gamma Pulsars的列表中。
We report on X-ray studies of the gamma-ray pulsar PSR J1418$-$6058 in the Rabbit pulsar wind nebula (PWN) carried out using archival Chandra and XMM-Newton observations. A refined timing analysis performed with the 120-ks XMM-Newton data finds significant ($p\approx10^{-7}$) pulsation at $P\approx110$ ms which is consistent with that measured with the Fermi large area telescope (LAT). In the Chandra image, we find extended emission around the pulsar similar to those seen around other pulsars in young PWNe, which further argues for association between PSR J1418$-$6058 and the Rabbit PWN. The X-ray spectrum of the pulsar is hard and similar to those of soft-gamma pulsars. Hence PSR J1418$-$6058 may add to the list of soft-gamma pulsars.
