摘要：IGR J11014-6103 is an hard X-ray INTEGRAL source, reported for the first time in the 4th IBIS/ISGRI catalog as an unidentified source. In this proceeding we report on our investigation of the nature of IGR J11014-6103 carried out through the analysis of public observations performed in the direction of the source from radio up to X- and
-rays energy domains. Our analysis revealed that, in the X-ray energy band, IGR J11014-6103 is comprised of three different regions: a cometary like “tail” (4 arcmin) and two compact sources, of which one is genuinely point-like, while the other has a modest extension ( 8 arcsec). These two sources are only 22 arcsec apart one from the other, and located at one end of the “tail”. No clear signs of timing variability were detected from the entire X-ray structure. A compact radio source positionally coincident with the head of the X-ray tail was also identified. Based on the discussed results, and comparison with other similar and known systems, we suggest that the emission from IGR J11014-6103 is generated by a pulsar wind nebula produced by a neutron star escaped from its supernova remnant and moving at very high velocity in the interstellar medium. IGR J11014-6103 might be the first of these systems detected with INTEGRAL IBIS/ISGRI.
