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: IGR J19173+0747, IGR J19294+1327 and IGR J19149+1036; the latter is positionally coincident with the Einstein source 2E 1912.5+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 (N_H~6x10^(22) cm^(-2)) power-law ({\\Gamma}~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.", "revisions": [ { "version": "v1", "updated": "2010-12-06T13:20:02.000Z" } ], "analyses": { "keywords": [ "integral sources", "infrared counterpart", "data analysis software", "einstein source 2e", "x-ray source ax" ], "tags": [ "journal article" ], "publication": { "journal": "Astronomy and Astrophysics", "year": 2011, "month": "Feb", "volume": 526 }, "note": { "typesetting": "TeX", "pages": 9, "language": "en", "license": "arXiv", "status": "editable", "inspire": 879528, "adsabs": "2011A&A...526A.122P" } } }
