论文摘要
巨大的玻色子，例如光标量和矢量玻色子，可以通过超高效应导致旋转黑洞的不稳定性，从而有效地从快速旋转的黑洞中提取能量和角动量。这个过程导致黑洞的旋转和周围的玻色子云的形成。在这项工作中，我们使用了从紫外线/光学或X射线观测值测量的超质量黑洞的质量和旋转来限制光玻色子的模型参数。我们发现，大量的轻玻色子从$ 10^{ - 22} $ eV到$ 10^{ - 17} $ eV可以在很大程度上被一组超级质量的黑洞所排除（包括极其巨大的OJ 287，TON 618和SDSS J140821.67+025733.2），特别是在Vector vecoration scector of vector，所谓的模糊暗物质参数区域。对于具有自我交互的标量玻色子，大部分质量范围从$ \ sim 3 \ times 10^{ - 19} $ eV到$ 10^{ - 17} $ eV，具有衰减常数$ f_a> 10^{15} $ gev，可以被排除，这令人信服地消除了这些群众的QCD轴轴。
Massive bosons, such as light scalars and vector bosons, can lead to instabilities of rotating black holes by the superradiance effect, which extracts energy and angular momentum from rapidly-rotating black holes effectively. This process results in spinning-down of black holes and the formation of boson clouds around them. In this work, we used the masses and spins of supermassive black holes measured from the ultraviolet/optical or X-ray observations to constrain the model parameters of the light bosons. We find that the mass range of light bosons from $10^{-22}$ eV to $10^{-17}$ eV can be largely excluded by a set of supermassive black holes (including also the extremely massive ones OJ 287, Ton 618 and SDSS J140821.67+025733.2), particularly for the vector boson scenario, which eliminates a good fraction of the so-called fuzzy dark matter parameter regions. For the scalar bosons with self-interaction, most part of the mass range from $\sim 3 \times 10^{-19}$ eV to $10^{-17}$ eV with a decay constant $f_a > 10^{15}$ GeV can be excluded, which convincingly eliminate the QCD axions at these masses.
