摘要 (Abstract): 

In this talk I would like to present our recent findings that eccentricties of the compact binaries in the Deci-Hz band can significantly improve the source localization of dark sirens, as well as the distance inference. I will first introduce the concepts of gravitational-wave standard sirens and their limits on cosmological applications. Then I will detailedly introduce our recent work which analyses the localization of dark sirens detected by DECIGO and the improvement led by eccentricities. Finally the discussion and implications will be given.
