Measuring Cosmic Growth Rate with CSST Spectroscopic Survey and Fast Radio Burst
Shi-Yuan Wang, Jun-Qing Xia
The cosmic growth rate, which is related to peculiar velocity and is a primary scientific objective of galaxy spectroscopic surveys, can be inferred from the Redshift Space Distort…
Constraints on Evolutions of Fundamental Constants from Clustering of Fast Radio Burst Dispersion Measure
Shi-Yuan Wang, Jun-Qing Xia
Constrained measurements of fundamental physical constants using astronomical observational data represent a powerful method for investigating potential new physics. In particular,…
Do JWST reionization (optical depth) puzzle, cosmological tensions, and CMB anomalies imply Harrison-Zel'dovich spectrum?
Hao-Hao Li, Xin-zhe Zhang, Taotao Qiu +1
The James Webb Space Telescope (JWST) has observed massive galaxies at high redshifts, which implies an earlier epoch of reionization (EoR) compared with the cosmic microwave backg…
Probing Cosmic Isotropy with the FAST All Sky HI Survey
Yi-Wen Wu, Jun-Qing Xia
This paper leverages the first released catalog from the FAST All Sky \textsc{Hi} Survey (FASHI) to examine the hypothesis of cosmic isotropy in the local Universe. Given the desig…
