Abstract (from CDS):

We take advantage of the high sensitivity of the IBIS/ISGRI telescope and the improvements in the data analysis software to investigate the nature of the still poorly known X-ray source AX J1910.7+0917, and search for closeby previously undetected objects. We analyze all publicly available INTEGRAL data of AX J1910.7+0917, together with a number of archival observations that were carried out in the direction of the source with Chandra, XMM-Newton, and ASCA. In the IBIS/ISGRI field-of-view around AX J1910.7+0917, we discovered three new sources: IGRJ19173+0747, IGRJ19294+1327 and IGRJ19149+1036; the latter is positionally coincident with the Einstein source 2E1912.5+1031. For the first two sources, we also report the results of follow-up observations carried out with Swift/XRT. AX J1910.7+0917 features a clear variability in the X-rays. Its spectrum can be well described with an absorbed (NH∼6x1022cm–2) power-law (Γ≃1.5) model plus an iron line at 6.4 keV. We also obtained a refined position and report on possible infrared counterparts. The present data do not allow for a unique classification of the sources. Based on the property of its X-ray emission and the analysis of a likely infrared counterpart, we investigate different possibilities for the nature of AX J1910.7+0917.
