色球蒸发模型对蒸发原始黑洞数密度的限制
Constraints on the Number Density of Evaporating Primordial Black Holes for the Chromospheric Evaporation Models
摘要：
利用Andyrchy阵列在2005.4 d的净观测周期内以单宇宙线探测模式获得的数据，寻找原始光子能量> 10 GeV的宇宙伽马射线暴。探测器计数率的波动分布与预期的宇宙射线背景一致，唯一的例外是偏差为7.9 σ的事件。在色球蒸发模型下，得到了银河系局部区域中蒸发原生黑洞数密度的约束条件。
英文摘要：
Cosmic gamma-ray bursts with primary-photon energies > 10 GeV are sought in the data from the Andyrchy array obtained in the mode of detection of a single cosmic-ray component during a net observation period of 2005.4 d. The distribution of fluctuations of the detector counting rate agrees with the expected cosmic-ray background, the only exception being an event with a deviation of 7.9 sigma. Constraints on the number density of evaporating primordial black holes in a local region of the Galaxy are obtained for the chromospheric evaporation models.
