利用超短伽马射线暴寻找原始黑洞

The Search for Primordial Black Holes Using Very Short Gamma Ray Bursts

摘要:

我们在银河系地图上显示了SWIFT短硬爆发(SHB)的位置,并与VSB BATSE事件进行了比较。正如我们之前指出的,在BATSE VSB事件的银河系地图中有过多的事件。我们不认为VSB SWIFT时代的事件都属于这一集群。需要更多的SWIFT事件来检查此声明。我们还报告了一项新的研究与KONUS数据的VSB样本的平均能量高于90千电子伏,显示了明显过剩的事件低于100毫秒的持续时间(T90),有大的平均能量质子。我们认为VSB本身由两个子类组成:一部分事件具有特殊的分布特性,并且没有可检测的对应物,这可能是对原始黑洞等外来源的预期。我们展示了GLAST如何为VSB爆发的研究增加关键的新信息,并有助于测试黑洞的概念。

英文摘要:

We show the locations of the SWIFT short hard bursts (SHB) with afterglows on the galactic map and compare with the VSB BATSE events. As we have pointed out before, there is an excess of events in the galactic map of BATSE VSB events. We not that none of VSB SWIFT era events fall into this cluster. More SWIFT events are needed to check this claim. We also report a new study with KONUS data of the VSB sample with an average energy above 90 keV showing a clear excess of events below 100 ms duration (T90) that have large mean energy protons. We suggest that VSB themselves consist of two subclasses: a fraction of events have peculiar distribution properties and have no detectable counterparts, as might be expected for exotic sources such as primordial black holes. We show how GLAST could add key new information to the study of VSB bursts and could help test the black hole concept.
