在2003-2005年INTEGRAL/IBIS数据中寻找X射线爆发并发现新的X射线爆发IGR J17364-2711/17380-3749

Search for X-ray bursts in the INTEGRAL/IBIS data of 2003-2005 and discovery of the new X-ray burster IGR J17364-2711/17380-3749

摘要:

在INTEGRAL天文台在轨运行的头2.5年期间,对使用该天文台上的IBIS望远镜进行的所有观测进行了分析,以发现X射线爆发。在IBIS/ISGRI探测器15-25 keV计数率的时间记录中,有1788个持续时间从5到500 s的统计学置信事件,其中319个是局部的,除了一个例外,被确定为持续的X射线源。已知的突发事件造成了215起局部事件。从AXJ1754.2-2754中检测到一个爆发,该爆发源以前未知为爆发源,另一个爆发来自新的爆发源。在确定它的位置时有双重性-它的名称可以是IGR J17364-2711或IGR J17380-3749。奇怪的是,这138次爆发是从一个X射线爆发器-- GX 354-0--上探测到的。

英文摘要:

All the observations performed with the IBIS telescope aboard the INTEGRAL observatory during the first 2.5 years of its in-orbit operation have been analyzed to find X-ray bursts. There were 1788 statistically confident events with a duration from 5 to 500 s revealed in time records of the 15-25 keV count rate of the IBIS/ISGRI detector, 319 of them were localized and, with one exception, identified with persistent X-ray sources. The known bursters were responsible for 215 of the localized events. One burst was detected from AXJ1754.2-2754, the source previously unknown as a burster, and another burst - from a new source. There was duality in determining its position - its name could be either IGR J17364-2711 or IGR J17380-3749. Curiously enough, the 138 bursts were detected from one X-ray burster - GX 354-0.
