Abstract
Discovery of three new INTEGRAL sources:IGR J18159-3353,IGR J20188 +3647,IGR J21117+3427 We report the discovery of three new hard X-ray sources detected with the IBIS/ISGRI telescope on board INTEGRAL: IGR J18159-3353, IGRJ20188+3647, IGRJ21117+3427. Each has been detected only in a single Science Window (ScW, about 2000 seconds exposure time) in the energy band 17-30 keV. No emission was detectable in adjacent ScWs; no detection is measured above 30 keV.
