Microlensing bias on the detection of strong lensing gravitational wave
Xikai Shan, Xuechun Chen, Bin Hu +1
Identifying strong lensing gravitational wave (SLGW) events is of utmost importance in astrophysics as we approach the historic first detection of SLGW amidst the growing number of…

We present a perturbative treatment of nonlinear galaxy clustering in the context of the cubic Galileon modified gravity model, in terms of 2nd order Lagrangian Perturbation theory…
Implication of the Hubble tension for the primordial Universe in light of recent cosmological data
Gen Ye, Bin Hu, Yun-Song Piao
In prerecombination resolutions of the Hubble tension, such as early dark energy, new physics before recombination shifts the values of relevant cosmological parameters so that the…
Lensing magnification: gravitational waves from coalescing stellar-mass binary black holes
Xikai Shan, Chengliang Wei, Bin Hu
Gravitational waves (GWs) may be magnified or de-magnified due to lensing. This phenomenon will bias the distance estimation based on the matched filtering technique. Via the multi…
Hubble parameter estimation via dark sirens with the LISA-Taiji network
Renjie Wang, Wen-Hong Ruan, Qing Yang +3
The Hubble parameter is one of the central parameters in modern cosmology, which describes the present expansion rate of the universe. Their values inferred from the late-time obse…
The first simultaneous measurement of Hubble constant and post-Newtonian parameter from Time-Delay Strong Lensing
Tao Yang, Simon Birrer, Bin Hu
Strong gravitational lensing has been a powerful probe of cosmological models and gravity. To date, constraints in either domain have been obtained separately. We propose a new met…

Simone Peirone, Noemi Frusciante, Bin Hu +2
We revisit the cosmology of Covariant Galileon gravity in view of the most recent cosmological data sets, including weak lensing. As a higher derivative theory, Covariant Galileon…
