黑洞的暗物质的Angular Momentum

Angular Momentum of Dark Matter Black Holes

Paul H. Frampton

摘要:

可能构成所有暗物质的假定黑洞由克尔度规描述,只有两个参数,质量M和角动量J。尽管如此,J在理解以前缺乏检测,特别是CMB失真方面确实发挥了核心作用。我们解释了为什么以前来自缺乏CMB失真的界限是太强的原始黑洞与J非零。几乎没有一个暗物质黑洞可以来自恒星坍缩,几乎所有的都是原始的,以避免过度的CMB扭曲。

英文摘要:

The putative black holes which may constitute all the dark matter are described by a Kerr metric with only two parameters, mass M and angular momentum J. There has been little discussion of J since it plays no role in the upcoming attempt at detection by microlensing. Nevertheless J does play a central role in understanding the previous lack of detection, especially of CMB distortion. We explain why bounds previously derived from lack of CMB distortion are too strong for primordial black holes with J non-vanishing. Almost none of the dark matter black holes can be from stellar collapse, and nearly all are primordial, to avoid excessive CMB distortion.
