Sound-Horizon-Independent Test of Cosmic Distance Duality Relation Using Artificial Neural Networks and Gaussian Processes
Bo-Hao Jiang, Guo-Jian Wang, Tao Yang
The cosmic distance duality relation (CDDR), , is a fundamental relation in modern cosmology linking luminosity distance and angular diamete…
Breaking the Dark Sector Degeneracy with Nonparametric Expansion--Growth Reconstruction
Changyu You, Rong-Gen Cai, Tao Yang
The dark energy equation of state (EoS) and a possible dark-sector interaction are degenerate at the level of background expansion: the same expansion history may be interpreted as…
Dynamical Dark Energy Implies a Coupled Dark Sector: Insights from DESI DR2 via a Data-Driven Approach
Changyu You, Dan Wang, Tao Yang
Recent observations from the Dark Energy Spectroscopic Instrument (DESI) Data Release 2 (DR2) have revealed compelling evidence for dynamical dark energy, challenging the CDM pa…
On Problems with Cosmography in Cosmic Dark Ages
Aritra Banerjee, Eoin Ó Colgáin, Misao Sasaki +2
Quasars show considerable promise as standard candles in a high-redshift window beyond Type Ia supernovae. Recently, Risaliti, Lusso \& collaborators \cite{Risaliti:2018reu, Lusso:…
