论文摘要
在2003 - 2018年以上IBIS/ISGRI望远镜的档案数据中，对宇宙伽马射线爆发（GRB）的系统搜索和其他简短的硬X射线事件已经进行。望远镜的视野已记录了七个以前未知的GRB。所有这些都以精度<2 arcmin进行了本地化。这些事件并未通过为自动GRB搜索和警报而设计的积分爆发警报系统（IBAS）揭示。 IBAS错过的另外四个此类局部事件，但以前已知，即在其他实验中观察到。还记录了八十八十六十六个GRB的视野外，还记录了与IBIS/ISGRI轴的大角度。所有这些都以前是在其他实验中记录的，主要是由SPI伽马射线光谱仪在板上积分，IBIS Gamma-ray望远镜的PICSIT检测器和Konus/Wind Monitor的PICSIT探测器，板上的抗收量屏蔽（ACS）记录。在其他实验中没有任何确认的情况下，更多的事件已被记录。 GRB和太阳耀斑或磁层瞬态事件都可以在其中。已经编译了具有IBIS/ISGRI记录的已确认和以前未知GRB的基本参数的目录。已经构建和研究了各种参数中突发的统计分布。
A systematic search for cosmic gamma-ray bursts (GRBs) and other short hard X-ray events in the archival data from the IBIS/ISGRI telescope of the INTEGRAL observatory over 2003-2018 has been carried out. Seven previously unknown GRBs have been recorded in the telescope field of view; all of them have been localized with an accuracy < 2 arcmin. These events were not revealed by the INTEGRAL burst alert system (IBAS) designed for an automatic GRB search and alert. Four more such localized events missed by IBAS, but known previously, i.e., observed in other experiments, have been found. Eight hundred and eighty six GRBs outside the field of view that arrived at large angles to the IBIS/ISGRI axis have also been recorded. All of them were previously recorded in other experiments, primarily by the anticoincidence shield (ACS) of the SPI gamma-ray spectrometer onboard INTEGRAL, the PICsIT detector of the IBIS gamma-ray telescope, and the KONUS/WIND monitor. An order of magnitude more events without any confirmations in other experiments have been recorded. Both GRBs and solar flares or magnetospheric transient events can be among them. Catalogs with the basic parameters of confirmed and previously unknown GRBs recorded by IBIS/ISGRI have been compiled. The statistical distributions of bursts in various parameters have been constructed and investigated.
