摘要:

IGRJ 11014 -6103是第四届IBIS/ISGRI星表中首次报道的尚未确认的硬X射线积分源之一。目的:我们调查了IGR J11014-6103的性质进行了多波长的分析,在源的方向进行了可用的档案观测。研究方法:首先,我们提出了所有的X射线观测IGR J11014-6103进行的ROSAT,ASCA,爱因斯坦,斯威夫特和XMM-牛顿的定时和光谱分析的结果,然后用它们来寻找可能的对应源在光学,红外,无线电和伽马射线域。结果如下:我们的分析显示,IGR J11014-6103由三个不同的X射线发射区组成:点状源,扩展对象和彗星状的“尾巴”(约4弧分)。一个可能的无线电对应物也被确定与源位置一致。结论:基于这些结果,我们认为IGR J11014-6103的辐射是由高速脉冲星产生的脉冲星风星云产生的。IGR J11014-6103可能是INTEGRAL IBIS/ISGRI检测到的第一个系统。

英文摘要:

Context: IGRJ11014-6103 is one of the still unidentified hard X-ray INTEGRAL sources, reported for the first time in the 4th IBIS/ISGRI catalog. Aims: We investigated the nature of IGR J11014-6103 by carrying out a multiwavelength analysis of the available archival observations performed in the direction of the source. Methods: We present first the results of the timing and spectral analysis of all the X-ray observations of IGR J11014-6103 carried out with ROSAT, ASCA, Einstein, Swift, and XMM-Newton, and then use them to search for possible counterparts to the source in the optical, infra-red, radio and gamma-ray domain. Results: Our analysis revealed that IGR J11014-6103 is comprised of three different X-ray emitting regions: a point-like source, an extended object and a cometary-like "tail" (~4 arcmin). A possible radio counterpart positionally coincident with the source was also identified. Conclusions: Based on these results, we suggest that the emission from IGR J11014-6103 is generated by a pulsar wind nebula produced by a high-velocity pulsar. IGR J11014-6103 might be the first of these systems detected with INTEGRAL IBIS/ISGRI.
