玻色子云在双黑洞系统上的遗留效应

Legacy of boson clouds on black hole binaries

Giovanni Maria Tomaselli, Thomas F. M. Spieksma, Gianfranco Bertone

AI总结:

本研究探究超轻玻色子超辐射云与双黑洞系统的共振演化,发现仅两种波形印记结果,为通过双黑洞族群统计分析探测新玻色子提供了可能。

摘要:

超轻玻色子的超辐射云可通过“电离”和“共振”在双黑洞的引力波形上留下印记。我们研究了双星演化过程中的共振序列,表明仅存在两种可能的结果,每种都会在波形上留下独特印记。若云与双星近乎反向旋转,则云会保持初始状态存续,直至进入未来引力波探测器(如LISA)的灵敏频段。在所有其他情形中,共振会摧毁云,同时驱使双星与云同向旋转,且其偏心率趋近于一个不动点。这为通过双黑洞族群的统计分析推断新玻色子的存在提供了可能性。

英文摘要:

Superradiant clouds of ultralight bosons can leave an imprint on the gravitational waveform of black hole binaries through "ionization" and "resonances." We study the sequence of resonances as the binary evolves, and show that there are only two possible outcomes, each with a distinct imprint on the waveform. If the cloud and the binary are nearly counter-rotating, then the cloud survives in its original state until it enters the sensitivity band of future gravitational wave detectors, such as LISA. In all other cases, resonances destroy the cloud, while driving the binary to co-rotate with it and its eccentricity close to a fixed point. This opens up the possibility of inferring the existence of a new boson from the statistical analysis of a population of black hole binaries.
