论文摘要
轻，小行星质量原始黑洞，其终生是宇宙年龄的数百万到数百万倍，是宇宙暗物质的动机候选人。使用档案COMPTEL数据，我们通过研究附近天体物理结构中的软伽玛射线蒸发对原始黑孔的允许参数空间的当前限制。我们指出，新一代提出的MEV伽马射线望远镜将提供独特的机会，可以直接从附近的暗物质密集区域观察到霍金蒸发，并限制或发现原始的黑孔暗物质。
Light, asteroid-mass primordial black holes, with lifetimes in the range between hundreds to several millions times the age of the universe, are well-motivated candidates for the cosmological dark matter. Using archival COMPTEL data, we improve over current constraints on the allowed parameter space of primordial black holes as dark matter by studying their evaporation to soft gamma-rays in nearby astrophysical structures. We point out that a new generation of proposed MeV gamma-ray telescopes will offer the unique opportunity to directly detect Hawking evaporation from observations of nearby dark matter dense regions and to constrain, or discover, the primordial black hole dark matter.
