黑洞光子球产生的普适$10^{20}$ Hz随机引力波

Universal $10^{20}$Hz stochastic gravitational waves from photon spheres of black holes

Kaishu Saito, Jiro Soda, Hirotaka Yoshino

摘要:

我们证明了超大质量黑洞的光子球通过光子-引力子转换产生高频随机引力波。值得注意的是,频率普遍被确定为根据质子质量$m_p$和电子质量$m_e$的$m_e\sqrt{m_e /m_p} \simeq 10^{20} \text{Hz}$。结果表明,随机引力波的密度参数$ Ω_{ \text{gw}}$可以是$ 10^{-12}$ .由于光子球中的引力波的存在是稳健的,因此,寻找探测$10^{20}$ Hz附近高频引力波的方法是值得的。

英文摘要:

We show that photon spheres of supermassive black holes generate high-frequency stochastic gravitational waves through the photon-graviton conversion. Remarkably, the frequency is universally determined as $m_e\sqrt{m_e /m_p} \simeq 10^{20} \text{Hz}$ in terms of the proton mass $m_p$ and the electron mass $m_e$. It turns out that the density parameter of the stochastic gravitational waves $ Ω_{ \text{gw}}$ could be $ 10^{-12}$. Since the existence of the gravitational waves from photon spheres is robust, it is worth seeking methods of detecting high-frequency gravitational waves around $10^{20}$Hz.
