摘要:

原始黑洞(PBH)可能是在早期宇宙中产生的,预计可以通过它们的霍金辐射探测到。费米伽马射线空间望远镜观测站对今天到期的初始质量为$\sim 5\times 10^{14}$ g的PBH产生的伽马射线暴提供了更高的灵敏度。PBH是缺乏X射线余辉的未确认的伽马射线暴(GRB)的候选祖先。我们提出光谱滞后,这是高,低能量脉冲之间的时间延迟,作为一种有效的方法来识别PBH蒸发事件与费米大面积望远镜(LAT)。

英文摘要:

Primordial Black Holes (PBHs), which may have been created in the early Universe, are predicted to be detectable by their Hawking radiation. The Fermi Gamma-ray Space Telescope observatory offers increased sensitivity to the gamma-ray bursts produced by PBHs with an initial mass of $\sim 5\times 10^{14}$ g expiring today. PBHs are candidate progenitors of unidentified Gamma-Ray Bursts (GRBs) that lack X-ray afterglow. We propose spectral lag, which is the temporal delay between the high and low energy pulses, as an efficient method to identify PBH evaporation events with the Fermi Large Area Telescope (LAT).
