无菌中微子暗物质致密晕的特征

Signatures of Compact Halos of Sterile-Neutrino Dark Matter

Florian Kuhnel, Tommy Ohlsson

摘要:

我们研究了无菌中微子暗物质的致密晕,并研究了中微子和光子发射的可观测特征。首先,我们考虑两种情况:原始黑洞晕和超紧凑的迷你晕。在这两种情况下,我们发现,存在一个广泛的可能的参数选择,这样的检测在不久的将来与X射线和伽马射线望远镜可能是很有可能的。事实上,当能量超过$10\,{\rm TeV}$时,中微子望远镜IceCube将是探测这种宏观暗物质候选者的绝佳机器。

英文摘要:

We investigate compact halos of sterile-neutrino dark matter and examine observable signatures with respect to neutrino and photon emission. Primarily, we consider two cases: primordial black-hole halos and ultra-compact mini-halos. In both cases, we find that there exists a broad range of possible parameter choices such that detection in the near future with X-ray and gamma-ray telescopes might be well possible. In fact, for energies above $10\,{\rm TeV}$, the neutrino telescope IceCube would be a splendid detection machine for such macroscopic dark-matter candidates.
