原始黑洞最终蒸发的证据：Swift、BATSE和KONUS以及VSGRB和具有PBH时间特征的VSB观测的比较
Evidence for Primordial Black Hole Final Evaporation: Swift, BATSE and KONUS and Comparisons of VSGRBs and Observations of VSB That Have PBH Time Signatures
摘要：
十多年前，我们发现了一类VSGRB（T90 < 100 ms）具有不寻常的特性：（1）星系位置不对称，（2）非常硬的伽马谱，（3）这些事件的星系起源的可能证据。我们现在研究最近的Swift数据，并表明存在与BATSE和KONUS一致的VSGRB增强。我们估计，这是一个总的4.5sigma观测。然后，我们研究VSB的PBH蒸发的时间结构预期的证据。几个事件显示了PBH蒸发的一般时间结构。如果是正确的，那么PBH一定存在于这个星系中。由于即使是像BATSE这样的大型探测器每年也只记录几个VSB，PBH的密度仍然很小，很难预测费米航天器LAT的速率。
英文摘要：
More than a decade ago we identified a class of VSGRB (T90 < 100 ms) as having unusual properties: (1) galactic position asymmetry, (2) very hard gamma spectrum, (3) possible evidence for galactic origin of these events. We now study the recent Swift data and show that a VSGRB enhancement consistent BATSE and KONUS exists. We estimate that this is now a total 4.5sigma observation. We then study the VSB for evidence of the time structure expected for PBH evaporation. Several of the events show the general time structure expected for PBH evaporation. If correct, then PBH must exist in this galaxy. Since even large detectors like BATSE record only a few VSB per year the density of PBH can still be very small and it is hard to predict a rate for the Fermi spacecraft LAT.
