Abstract (from CDS):
IGRJ11014-6103 is one of the still unidentified hard X-ray INTEGRAL sources, reported for the first time in the 4th IBIS/ISGRI catalog. We investigated the nature of IGRJ11014-6103 by carrying out a multiwavelength analysis of the available archival observations performed in the direction of the source. We present the results of the timing and spectral analysis of all the X-ray observations of IGRJ11014-6103 carried out with ROSAT, ASCA, Einstein, Swift, and XMM-Newton. We used them to search for possible counterparts to the source in the optical, infrared, radio and γ-ray domain. Our analysis reveals that IGRJ11014-6103 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. Based on these results, we suggest that the emission from IGRJ11014-6103 is generated by a pulsar wind nebula produced by a high-velocity pulsar. IGRJ11014-6103 might be the first of these systems detected with INTEGRAL IBIS/ISGRI.
