论文摘要
我们表明，由根据质量光谱分布的点微透镜诱导的类星体微透析放大统计量可以很好地近似于单个质量“单色”，人口。与爱因斯坦半径相比，当空间分辨率（由源尺寸物理定义）很小时，单色群体的质量与质量光谱的几何平均值相匹配。否则，最佳拟合质量可能会更大。 Taking into account the degeneracy with the geometric mean, the interpretation of quasar microlensing observations under the hypothesis of a mixed population of primordial black holes and stars, makes the existence of a significant population of intermediate mass black holes ($\sim$ 100$M_\odot$) unlikely but allows, within a two-$σ$ confidence interval, the presence of a large population ($\gtrsim 40\%$ of替代黑洞的总质量（$ \ sim $ 0.01 $ m_ \ odot $）。
We show that quasar microlensing magnification statistics induced by a population of point microlenses distributed according to a mass-spectrum can be very well approximated by that of a single-mass, "monochromatic", population. When the spatial resolution (physically defined by the source size) is small as compared with the Einstein radius, the mass of the monochromatic population matches the geometric mean of the mass-spectrum. Otherwise, the best-fit mass can be larger. Taking into account the degeneracy with the geometric mean, the interpretation of quasar microlensing observations under the hypothesis of a mixed population of primordial black holes and stars, makes the existence of a significant population of intermediate mass black holes ($\sim$ 100$M_\odot$) unlikely but allows, within a two-$σ$ confidence interval, the presence of a large population ($\gtrsim 40\%$ of the total mass) of substellar black holes ($\sim$ 0.01$M_\odot$).
