FLRW Kinematic-Induced Measurement of the Hubble Constant from Cosmic Chronometer and Redshift Drift Observations
Kang Jiao, Tong-Jie Zhang, Liang Gao +1
We present a geometric embedding method that exploits the exact kinematic relation to transform redshift misalignment between Cosmic Chronometer (CC)…

Exploring the anisotropic gravitational wave background from all-sky mock gravitational wave event catalogues
Zhencheng Li, Zhen Jiang, Yun Liu +4
Anisotropic stochastic gravitational wave background (SGWB) serves as a potential probe of the large-scale structure (LSS) of the universe. In this work, we explore the anisotropic…

Baryon Acoustic Oscillations analyses with Density-Split Statistics
Tengpeng Xu, Yan-Chuan Cai, Yun Chen +3
Accurate modeling for the evolution of the Baryon Acoustic Oscillations (BAO) is essential for using it as a standard ruler to probe cosmology. We explore the non-linearity of the…
