从2003年8月23日到9月24日，INTEGRAL天文台对银河系中心区域进行了一次深度调查，其能量超过20kev的灵敏度破纪录。我们分析了IBIS望远镜（15 - 200kev）的ISGRI探测器获得的银河系中心区域图像，并给出了探测到的源目录。我们总共发现了60个通量超过1.5 mCrab的源，其中44个和3个分别被确定为银河系中不同类别的双星系统和星系外天体。我们发现了一个新的来源。
From August 23 through September 24, 2003, the INTEGRAL Observatory conducted a deep survey of the Galactic-Center region with a record-breaking sensitivity at energies above 20 keV. We have analyzed the images of the Galactic-Center region obtained with the ISGRI detector of the IBIS telescope (15–200 keV) and give a catalog of detected sources. We detected a total of 60 sources with fluxes above 1.5 mCrab, 44 and 3 of which were previously identified as binary systems of different classes in our Galaxy and as extragalactic objects, respectively. We discovered one new source.
