XGIS-THESEUS对原初黑洞的未来约束
Future Constraints on Primordial Black Holes from XGIS-THESEUS
摘要：
目前的观测结果允许小行星质量范围为$10^{17}-10^{22}$ g的原始黑洞（PBH）构成整个暗物质（DM）的能量密度（排除21 cm观测所限制的小质量范围）。在这项工作中，我们探讨了探测PBH的质量$10^{17}-10^{19}\,{\rm g}$通过即将到来的X和伽马成像光谱仪（XGIS）望远镜阵列上的瞬态高能天空和早期宇宙探测器（THESEUS）的任务的可能性。虽然我们预计的限制与文献中提出的$10^{16}\,{\rm g}\,<\,M_{\mathrm{PBH}}\,<\,10^{17}\,{\rm g}$，我们表明，XGIS-THESEUS任务可以提供最强的约束$10^{17} \mathrm{~g}<M_{\mathrm{PBH}} \lesssim 3\times 10^{18} \mathrm{~g}$非旋转PBH。对于质量范围为$5\times10^{15}\,{\rm g}\,<\,M_{\rm PBH}\,\lesssim\,10^{19}\,{\rm g}$的最大旋转PBH，边界变得更加严格，接近一个数量级。
英文摘要：
Current observations allow Primordial Black Holes (PBHs) in asteroid mass range $10^{17}-10^{22}$ g to constitute the entire dark matter (DM) energy density (barring a small mass range constrained by 21 cm observations). In this work, we explore the possibility of probing PBH with masses $10^{17}-10^{19}\,{\rm g}$ via upcoming X and Gamma Imaging Spectrometer (XGIS) telescope array on-board the Transient High-Energy Sky and Early Universe Surveyor (THESEUS) mission. While our projected limits are comparable with those proposed in the literature for $10^{16}\,{\rm g}\,<\,M_{\mathrm{PBH}}\,<\,10^{17}\,{\rm g}$, we show that the XGIS-THESEUS mission can potentially provide the strongest bound for $10^{17} \mathrm{~g}<M_{\mathrm{PBH}} \lesssim 3\times 10^{18} \mathrm{~g}$ for non-rotating PBHs. The bounds become more stringent by nearly an order of magnitude for maximally rotating PBHs in the mass range $5\times10^{15}\,{\rm g}\,<\,M_{\rm PBH}\,\lesssim\,10^{19}\,{\rm g}$.
