Testing Departures from the CDM model in f(T) Gravity with DESI DR2
Jie Zheng, Mingzhi Wang, Ming Zhang
Recent analyses combining DESI baryon acoustic oscillation (BAO) measurements with other cosmological observations have reported indications of departures from the CDM model wit…
Testing Gravity with DESI DR2 and Strong-Lensing Time Delays
Darshan Kumar, Saibal Ray, Fengge Zhang +3
Symmetric teleparallel gravity provides an alternative description of gravitation in which non-metricity replaces curvature and torsion. Its extension through gravity offers…
Revisiting the equation of state of dark energy from DESI BAO with SNe Ia and CMB
Jie Zheng, Da-Chun Qiang, Zhi-Qiang You +1
The Dark Energy Spectroscopic Instrument (DESI) measurements of baryon acoustic oscillations (BAO) have recently shown a mild preference for dynamical dark energy over the standard…
From Nonparametric Distance Reconstruction to Testing the Etherington Relation and Cosmic Curvature Using 2D and 3D BAO Measurements
Darshan Kumar, Jie Zheng, Zhi-Qiang You +1
We present a joint test of cosmic curvature, , and the cosmic distance-duality relation (CDDR) using the Etherington relation, which connects the luminosity and angular dia…
The impact of 2D and 3D BAO measurements on the Cosmic Distance Duality Relation with HII galaxies
Jie Zheng, Da-Chun Qiang, Zhi-Qiang You +1
The cosmic distance duality relation (CDDR) is a fundamental and practical condition in observational cosmology that connects the luminosity distance and angular diameter distance.…
Cosmological constraints on dark energy models using DESI BAO 2024
Jie Zheng, Da-Chun Qiang, Zhi-Qiang You
Recently, the measurements of baryon acoustic oscillations (BAO) by the Dark Energy Spectroscopic Instrument (DESI) indicate a potential deviation from the standard CDM model. S…
Unsupervised Machine Learning for Classifying CHIME Fast Radio Bursts and Investigating Empirical Relations
Da-Chun Qiang, Jie Zheng, Zhi-Qiang You +1
Fast Radio Bursts (FRBs) are highly energetic millisecond-duration astrophysical phenomena typically categorized as repeaters or non-repeaters. However, observational limitations m…
Probing the shape of the primordial curvature power spectrum and the energy scale of reheating with pulsar timing arrays
Lele Fan, Jie Zheng, Fengge Zhang +1
The stochastic gravitational wave background (SGWB) provides a unique opportunity to probe the early Universe, potentially encoding information about the primordial curvature power…
Joint observations of late universe probes: cosmological parameter constraints from gravitational wave and Type Ia supernova data
Jie Zheng, Xiao-Hui Liu, Jing-Zhao Qi
The growing tensions between the early Universe and the late Universe increasingly highlight the importance of developing precise probes for late cosmology. As significant late-Uni…
