论文摘要
我们调查了质量区域中对大男子气概的公开约束$ 10^2-10^5 m _ {\ odot} $及其对暗物质的可能贡献。我们专注于依赖物质积聚的约束,这些物质会发出X射线,这些X射线可以将X射线降级到微波后,转移到CMB光谱和各向同性的变形。这一参数链中最可疑的步骤是使用过度简化的积聚模型。我们比较了相同的积分模型如何适用于超级质量黑洞SMBHS,M87和SGR A*的X射线观测值。这两个SMBH与中间质量大男子的比较表明,后者毕竟可以提供所有暗物质的成分。我们讨论了对IM-Machos的其他约束的状态。
We investigate the published constraints on MACHOs in the mass region $10^2 - 10^5 M_{\odot}$ and their possible contribution to dark matter. We focus on constraints which rely on the accretion of matter which emits X-rays that can lead, after downgrading to microwaves, to distortion of the CMB spectrum and isotropy. The most questionable step in this chain of arguments is the use of overly simplified accretion models. We compare how the same accretion models apply to X-ray observations from supermassive black holes SMBHs, M87 and Sgr A*. The comparison of these two SMBHs with intermediate mass MACHOs suggests that the latter could, after all, provide the constituents of all the dark matter. We discuss the status of other constraints on IM-MACHOs.
