小行星质量原初黑洞霍金辐射的直接探测

Direct Detection of Hawking Radiation from Asteroid-Mass Primordial Black Holes

Adam Coogan, Logan Morrison, Stefano Profumo

摘要:

轻的、小行星质量的原始黑洞,其寿命在宇宙年龄的几百到几百万倍之间,是宇宙学暗物质的有力候选者。使用档案COMPTEL数据,我们改善了目前的限制,允许的参数空间的原始黑洞作为暗物质,通过研究它们的蒸发到附近的天体物理结构中的软伽马射线。我们指出,新一代的建议兆电子伏伽马射线望远镜将提供独特的机会,直接检测霍金蒸发附近的暗物质密集区的观测和约束,或发现,原始黑洞暗物质。

英文摘要:

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.
