摘要：IGR J17091–3624 and IGR J17098–3628 are two X-ray transients discovered by INTEGRAL and classified as black hole candidates (BHCs). The behaviour of these two sources has been monitored thanks to the analysis of amulti-wavelength data sets collected by different instruments from 2005 until 2008. Since part of this work will be published in the Astrophysical Journal (January 2009), this proceeding is mostly dedicated to the latest outcoming results of this study developed during 2008. In particular we show here the results of the 2008 Swift ToO data analysis during which IGR J17098–3628 was in a bright soft state while IGR J17091-3624 was not detectable. We also report in this paper on a tentative searching of the counterpart of IGR J17091-3624 in the infrared archives.
