Abstract (from CDS):

We report on the first broadband (1-200 keV) simultaneous Chandra-INTEGRAL observations of the recently discovered hard X-ray transient IGR J17177-3656 that took place on 2011 March 22, about two weeks after the source discovery. The source had an average absorbed 1-200 keV flux of about 8x10–10 erg/cm2/s. We extracted a precise X-ray position of IGR J17177-3656, αJ2000 = 17h17m42.s62, δJ2000= -36°56'04".5 (90% uncertainty of 0".6). We also report Swift, near-infrared, and quasi-simultaneous radio follow-up observations. With the multi-wavelength information at hand, we propose IGR J17177-3656 is a low-mass X-ray binary, seen at high inclination, probably hosting a black hole.
