We present our near-infrared ESO-NTTKS band observations of the field of IGRJ17448-3232which show no extended emission consistent with the supernova remnant (SNR), but in whichwe identify a new counterpart, also visible in Spitzer images up to 24 µm, at the position of theX-ray point source, CXOUJ174437.3-323222. Multiwavelength spectral modelling showsthat the data are consistent with a reddened and absorbed single power law over 5 orders ofmagnitude in frequency. This implies non-thermal, possibly synchrotron emission that rendersthe previous identification of this source as a possible pulsar, and its association to the SNR,unlikely; we instead propose that the emission may be due to a blazar viewed through theplane of the Galaxy. | |
