Milky Way星系中双星黑洞的LISA探测

LISA Detection of Binary Black Holes in the Milky Way Galaxy

Pierre Christian, Abraham Loeb

摘要:

利用LIGO的黑洞合并率,我们计算了银河系中紧束缚双黑洞的丰度。具有小半长轴的双星($\lesssim 10 R_\odot$)通过传统的形成机制起源于较大的分离,并作为引力波发射的结果而演化。我们发现LISA可以在银河系中探测到它们。我们还确定了可能的X射线签名,这样的二进制文件。

英文摘要:

Using the black hole merger rate inferred from LIGO, we calculate the abundance of tightly bound binary black holes in the Milky Way galaxy. Binaries with a small semimajor axis ($\lesssim 10 R_\odot$) originate at larger separations through conventional formation mechanisms and evolve as a result of gravitational wave emission. We find that LISA could detect them in the Milky Way. We also identify possible X-ray signatures of such binaries.
