The detectability of single spinless stellar-mass black holes through gravitational lensing of gravitational waves with advanced LIGO

Chengjiang Yin, Jian-hua He

Abstract

We investigate the detectability of gravitational waves that have been lensed by a spinless stellar-mass black hole, with respect to the advanced LIGO. By solving the full relativistic linear wave equations in the spacetime of a Schwarzschild black hole, we find that the strong gravity can create unique signals in the lensed waveform, particularly during the merger and ringdown stages. The differences in terms of fitting factor between the lensed waveform and best-fitted unlensed general relativity template with spin-precessing and higher-order multipoles are greater than $5\%$ for the lens black hole mass within $70M_{\odot}<M_{\rm lens}<133.33 M_{\odot}$ under advanced LIGO's sensitivity. This is up to 5 times more detectable than the previous analysis based on the weak field approximation for a point mass and covers most part of the black hole mass gap predicted by stellar evolution theory. Based on Bayesian inference, the lensing feature can be distinguished with a signal-to-noise ratio of 12.5 for $M_{\rm lens}=70 M_{\odot}$ and 19.2 for $M_{\rm lens}=250 M_{\odot}$, which is attainable for advanced LIGO.

    • Since the article doesn't link to any example HTML article, here's a random link: https://browse.arxiv.org/html/2312.12451v1 It's cool that it has a dark mode. Didn't see a toggle but renders in the system mode. Overall will make arXiv a lot more accessible on mobile.

    • https://browse.arxiv.org/html/2312.12451v1#bib.bib1 works, but https://browse.arxiv.org/html/2312.12451v1/#bib.bib1 doesn't.

    • Not on arXiv (unless I'm much mistaken), which is a preprint server, not a conventional journal. arXiv accepts various flavors of TeX, or PDFs not produced by TeX [0], and automatically produces PDFs and HTML where possible (e.g. if TeX is submitted). In the case of the example…

    • Yes it does, e.g. compare the pdf [1] and corresponding html [2]. [1] https://arxiv.org/pdf/2312.12451.pdf [2] https://browse.arxiv.org/html/2312.12451v1
