摘要

原始黑洞(PBHs),更广义地说是BHs,会发生蒸发,原则上会在高能伽马射线爆发中结束自己的生命。值得注意的是,初始质量为 1014 g 的 PBHs 将在今天结束自己的生命。在这项工作中,我们评估了大型高空气流淋浴天文台(LHAASO)在探测PBHs本地爆发率密度方面的潜在灵敏度。我们的结果表明,LHAASO 能够探测距离太阳 ∼ 0.1 pc 范围内的 PBH 爆,在为期 3 年(或 5 年)的观测活动中,以 99% 的置信度测量出 ∼ 1200(或 700)pc-3 yr-1 的本地爆率密度。这一灵敏度超过了高海拔水切伦科夫天文台(HAWC)提供的最严格的观测约束,超出了一个数量级。此外,我们还提出了 LHAASO 的数据分析策略,以优化对 PBHs 的搜索并达到其潜在的探测极限。

Search for the Hawking radiation of primordial black holes: prospective sensitivity of LHAASO
Primordial black holes (PBHs), more generally, BHs, undergo evaporation and, in principle, will end their lives in bursts of very high-energy gamma rays. The notable aspect of the PBHs with an initial mass of ∼ 1014 g is that they are expected to end their lives today. In this work, we assess the potential sensitivity of the Large High Altitude Air Shower Observatory (LHAASO) in detecting the local burst rate density of PBHs. Our results suggest that LHAASO is capable of probing for PBH bursts within a proximity of ∼ 0.1 pc from the Sun, measuring a local burst rate density of ∼ 1200 (or 700)pc-3 yr-1 with 99% confidence during a 3-year (or 5-year) observational campaign. This level of sensitivity surpasses the most rigorous observational constraint provided by the High Altitude Water Cherenkov Observatory (HAWC) by an order of magnitude. Additionally, we propose data analysis strategies for LHAASO to optimize the search for PBHs and reach its potential detection limits.

期刊介绍: Journal of Cosmology and Astroparticle Physics (JCAP) encompasses theoretical, observational and experimental areas as well as computation and simulation. The journal covers the latest developments in the theory of all fundamental interactions and their cosmological implications (e.g. M-theory and cosmology, brane cosmology). JCAP''s coverage also includes topics such as formation, dynamics and clustering of galaxies, pre-galactic star formation, x-ray astronomy, radio astronomy, gravitational lensing, active galactic nuclei, intergalactic and interstellar matter.
