论文摘要
对原始黑洞的最强限制在$ m _ {\ rm bh} \ sim 10^{15} -10^{17} {17} \，{\ rm g} $中衍生自本地cosmic-ray electon-ray-ray-ray-potitron by voyager by voyager by voyager 1＆mev ray by voyager and mev ray voyage by voyager y ynnestion and mev ray rak rak ray voyage by g raa comptel和积分。在本文中，我们评估了未来MEV尺度伽马射线望远镜（例如E-Astrogam或Amego）的敏感性。我们表明，这种仪器将能够在$ m _ {\ rm bh} \ sim（0.6-20）\ times 10^{16} \，{\ rm g} $的质量范围内提供最强大的约束，通常超过了两个次数。在观察到的511 keV过量的情况下，鹰辐射的结果是，我们发现e-astrogam或amego不仅能够从内部银河系中检测到鹰辐射，而且可以精确测量负责该信号的黑洞的丰度和质量分布。
The strongest existing constraints on primordial black holes with masses in the range of $m_{\rm BH} \sim 10^{15}-10^{17} \, {\rm g}$ have been derived from measurements of the local cosmic-ray electron-positron flux by Voyager 1, and MeV-scale gamma-ray observations of the Inner Galaxy by COMPTEL and INTEGRAL. In this paper, we evaluate the sensitivity of future MeV-scale gamma-ray telescopes such as e-ASTROGAM or AMEGO to Hawking radiation. We show that such an instrument would be able to provide the strongest constraints on black holes in the mass range of $m_{\rm BH} \sim (0.6-20) \times 10^{16} \, {\rm g}$, typically exceeding current constraints by approximately two orders of magnitude. In scenarios in which the observed 511 keV excess is the result of Hawking radiation, we find that e-ASTROGAM or AMEGO would not only be able to detect the Hawking radiation from the Inner Galaxy, but could precisely measure the abundance and mass distribution of the black holes responsible for this signal.
