论文摘要
最近的伽马射线和宇宙射线观察结果对我们宇宙中原始黑洞(PBH)的数量施加了强烈的限制。在本文中,我们使用内部银河中心的档案无线电数据来限制三种不同的PBH质量分布在内的PBH与暗物质的比率,包括单色,对数正态和幂律。我们表明,PBH的量仅构成了银河中心的深色物质的非常小的组成部分,用于大型参数空间。
Recent gamma-ray and cosmic-ray observations have put strong constraints on the amount of primordial black holes (PBHs) in our universe. In this article, we use the archival radio data of the inner Galactic Centre to constrain the PBH to dark matter ratio for three different PBH mass distributions including monochromatic, log-normal and power-law. We show that the amount of PBHs only constitutes a very minor component of dark matter at the Galactic Centre for a large parameter space.
