论文摘要
我们讨论将原始热量2-2孔残留物作为暗物质的天体物理和宇宙学含义。二次重力中的热2-2孔作为相对论热气体的超跨分布分布的二次重力。与模仿黑洞的热力学行为的大型2-2孔相反,在蒸发后期,一个小的2-2孔表现为稳定的残留物,质量接近最小值。这些残余物作为所有暗物质都可以满足相应的观察限制,但前提是形成和残余质量相对较小。通过可能产生高能量天体物理颗粒的强磁通量来探测残留质量的参数空间。高能光子和中微子数据似乎有利于Planck-Mass残余物,指出了二次重力量子理论的强耦合方案。另一方面,形成质量受到早期宇宙宇宙学的约束,事实证明,在大爆炸核合成之前,它需要2-2孔才能进化为残余状态。
We discuss the astrophysical and cosmological implications of having primordial thermal 2-2-hole remnants as dark matter. Thermal 2-2-holes emanate in quadratic gravity as horizonless classical solutions for ultracompact distributions of relativistic thermal gas. In contrast to a large 2-2-hole that imitates the thermodynamic behaviour of a black hole, a small 2-2-hole at late stages of evaporation behaves as a stable remnant with the mass approaching a minimal value. These remnants as all dark matter can satisfy the corresponding observational constraints provided that both the formation and remnant masses are relatively small. The parameter space for the remnant mass is probed through possible remnant mergers that would produce strong fluxes of high-energy astrophysical particles; the high-energy photon and neutrino data appear to favor towards the Planck-mass remnants, pointing to the strong-coupling scenario for the quantum theory of quadratic gravity. The formation mass, on the other hand, is constrained by the early-universe cosmology, which turns out to require 2-2-holes to evolve into the remnant state before Big Bang Nucleosynthesis.
