Probing Dark Matter Substructure with Wave-Optics Distortions of Strongly Lensed LISA Gravitational Waves
Tonghua Liu, Kai Liao, Marek Biesiada +1
Strong lensing changes the phase of a gravitational-wave signal as well as its amplitude and arrival time. We study whether this phase information can distinguish between three dar…
A model-independent determination of the sound horizon using recent BAO measurements and strong lensing systems
Tonghua Liu, Shuo Cao, Jieci Wang
We propose an improved method to determine the sound horizon in a cosmological model-independent way by using the latest observations of BAO measurements from DES, BOSS/eBOSS, and…
Model independent calibration for sound horizon combining observations of supernovae and transversal BAO measurements
Tonghua Liu, Xinyi Zhong, Jieci Wang +1
The sound horizon is a key theoretical prediction of the cosmological model that depends on the speed of sound and the rate of expansion in the early universe, before matter and ra…
Model-independent way to determine the Hubble constant and the curvature from phase shift of gravitational waves with DECIGO
Tonghua Liu, Shuo Cao, Marek Biesiada +2
In this Letter, we propose a model-independent method to determine the Hubble constant and curvature simultaneously taking advantage of the possibilities of future space-borne grav…
Multiple measurements on the cosmic curvature using Gaussian process regression without calibration and a cosmological model
Xiaolong Gong, Yifei Xu, Tonghua Liu +4
In this letter, we propose an improved cosmological model-independent method to measure cosmic curvature, combining the recent measurements of transverse and line-of-sight directio…
Measurements of the Hubble constant from combinations of supernovae and radio quasars
Tonghua Liu, Xiyan Yang, Zisheng Zhang +2
In this letter, we propose an improved cosmological model independent method of determining the value of the Hubble constant . The method uses unanchored luminosity distances…
What are recent observations telling us in light of improved tests of distance duality relation?
Liu Tonghua, Cao Shuo, Ma Shuai +3
As an exact result required by the Etherington reciprocity theorem, the cosmic distance duality relation (CDDR), plays an essential part in modern…
