利用档案 X 射线数据,我们发现了点状 X 射线对应候选者,其位置与 Einstein@Home 项目最近在费米伽马射线太空望远镜数据中发现的六颗 $gamma$ 射线脉冲星一致。使用 Swift 检测 PSR J0002$+$6216、J0554$+$3107、J1844$-$0346 和 J1105$-$6037 的候选者,使用 Chandra 检测 PSR J0359$+$5414 和 J2017$+$3625 的候选者。尽管某些候选星的计数统计数据较低,但假设对脉冲星的吸收柱密度存在合理的限制,我们表明所有候选星的 X 射线光谱特性与其他脉冲星的观测结果一致。 J0359$+$5414 是最可靠的识别对象。我们检测到它周围有一个星云,其光谱和范围表明这是一个由脉冲星驱动的脉冲星风星云。提出了 J0002$+$6216 和 J1844$-$0346 与超新星遗迹 CTB 1 和 G28.6$-$0.1 的关联。
Using archival X-ray data we have found point-like X-ray counterpart candidates positionally coincident with six $gamma$-ray pulsars discovered recently in the Fermi Gamma-ray Space Telescope data by the Einstein@Home project. The candidates for PSRs J0002$+$6216, J0554$+$3107, J1844$-$0346 and J1105$-$6037 are detected with Swift, and those for PSRs J0359$+$5414 and J2017$+$3625 are detected with Chandra. Despite a low count statistics for some candidates, assuming plausible constraints on the absorbing column density towards the pulsars, we show that X-ray spectral properties for all of them are consistent with those observed for other pulsars. J0359$+$5414 is the most reliably identified object. We detect a nebula around it, whose spectrum and extent suggest that this is a pulsar wind nebula powered by the pulsar. Associations of J0002$+$6216 and J1844$-$0346 with supernova remnants CTB 1 and G28.6$-$0.1 are proposed.
