摘要:

暗宇宙的显现始于意想不到的大规模天文观测。在这里,我们正在研究小尺度异常的起源,比如每年观测到的平流层温度异常。出乎意料的是,我们观察到了一个行星的关系,每天平流层温度分布。它的光谱形状与同时发生的太阳活动或太阳极紫外辐射不匹配,后者对大气的影响是明确的。这种行为指向太阳系外起源的额外能源。这种观测背后的一个可行的概念是基于太阳系可能对地球的低速不可见物质的引力聚焦。我们将暗宇宙中的一般成分称为不可见物质,以便将它们与普通的暗物质候选者(如轴子或WIMP)区分开来,后者不会对平流层产生任何明显的影响。观测到的行星峰值关系本身排除了任何传统的解释。只有一种看不见的流动物质与平流层上层(noverhead约1 gr/cm 2)之间的强烈相互作用,才可能是偶尔观察到的温度升高的原因。我们还估计了一个相关的能量沉积O(W/m2),这是在11年的太阳周期的变化。对于一个广泛假设的准不相互作用的暗宇宙的图片,这个新的太阳能是巨大的。由于几十年来一直不间断地监测大气层,它也可以寄生地作为一种新的低阈值探测器的暗宇宙,与内置的时空分辨率和太阳系临时充当信号放大器。在未来,分析更多的观测,例如,从异常电离层,或,短暂的突然平流层变暖,假设的无形流的性质可以破译。

英文摘要:

The manifestation of the dark Universe begun with unexpected large scale astronomical observations. Here we are investigating the origin of small scale anomalies, like that of the annually observed temperature anomalies in the stratosphere. Unexpectedly, we observe a planetary relationship of the daily stratospheric temperature distribution. Its spectral shape does not match concurrent solar activity, or solar EUV emission, whose impact on the atmosphere is unequivocal. This behavior points at an additional energy source of exosolar origin. A viable concept behind such observations is based on possible gravitational focusing by the solar system towards the Earth of low speed invisible matter. We denote generic constituents from the dark Universe as invisible matter, in order to distinguish them from ordinary dark matter candidates like axions or WIMPs, which cannot have any noticeable impact on the stratosphere. The observed peaking planetary relations exclude on their own any conventional explanation. Only a somehow strongly interacting invisible streaming matter with the little screened upper stratosphere (noverhead about 1 gr/cm 2) can be behind the occasionally observed temperature increases. We also estimate an associated energy deposition O(W/m 2), which is variable over the 11 years solar cycle. For the widely assumed picture of a quasi not interacting dark Universe, this new exosolar energy is enormous. Since the atmosphere is uninterruptedly monitored since decades, it can serve also parasitically as a novel low threshold detector for the dark Universe, with built-in spatiotemporal resolution and the solar system acting temporally as signal amplifier. In future, analyzing more observations, for example, from the anomalous ionosphere, or, the transient sudden stratospheric warmings, the nature of the assumed invisible streams could be deciphered.
