论文摘要
太阳质量范围内的原始黑洞可能是暗物质的重要组成部分。我们展示了可能存在于M87超级黑洞周围的密度尖峰中这种黑洞偏转的论点,并结合了EHT协作的高分辨率观察结果,可以在天体相关的质量范围内对原始黑洞质量分数产生强大的限制。结果取决于暗物质尖峰假定的模型,并提出了进一步理解此类尖峰的兴趣,以及对超质量黑洞的进一步高分辨率观察。
Primordial black holes in the solar mass range are a possibly significant component of dark matter. We show how an argument relating the deflection of light by such black holes in the density spike likely to exist around the M87 supermassive black hole, combined with the high resolution observations of the EHT collaboration, can lead to a strong limits on the primordial black hole mass fraction in an astrophysically relevant mass range. The results depend on the model assumed for the dark matter spike and suggest the interest of further understanding of such spikes as well as further high resolution observations on supermassive black holes.
