论文摘要
在过去的十年中，通过各种数据检查了消灭暗物质模型的特性，包括伽玛射线，无线电波，X射线，正电子，电子，抗脂子和中微子的数据。特别是，大多数研究都集中在我们的星系，附近星系（例如M31星系）或附近星系簇（例如Fornax群集）的数据上。在本文中，我们研究了相对高的红移星系群（A697群集）的档案无线电连续频谱数据，以限制歼灭暗物质的性质。我们发现嗜血式歼灭通道（$ e^+e^ - $，$μ^+μ^ - $和$τ^+τ^ - $）可以为A697群集的无线电连续频谱提供非常好的拟合。
In the past decade, the properties of annihilating dark matter models were examined by various kinds of data, including the data of gamma rays, radio waves, X-ray, positrons, electrons, antiprotons and neutrinos. In particular, most of the studies focus on the data of our Galaxy, nearby galaxies (e.g. M31 galaxy) or nearby galaxy clusters (e.g. Fornax cluster). In this article, we examine the archival radio continuum spectral data of a relatively high-redshift galaxy cluster (A697 cluster) to constrain the properties of annihilating dark matter. We find that leptophilic annihilation channels ($e^+e^-$, $μ^+μ^-$ and $τ^+τ^-$) can give very good fits to the radio continuum spectrum of the A697 cluster.
