From Scalar to : A Reformulation of the Hubble Tension
Seokcheon Lee
The Hubble tension is usually expressed as a discrepancy between the low H_0 inferred from Planck CMB data within base \LambdaCDM and the higher value obtained from late-time dista…
Complementary Roles of Distance and Growth Probes in Testing Time-Varying Dark Energy
Seokcheon Lee
Distance measurements have long provided the primary observational constraints on the expansion history of the Universe and the properties of dark energy. However, because such obs…
Structural Limitations on Constraining the Time Evolution of Dark Energy
Seokcheon Lee
Cosmological constraints on a time-varying dark energy equation of state are fundamentally limited by the integral structure through which the equation of state enters cosmological…
Controlled Tension Forecasting: Quantifying Cross-Probe Biases in CDM
Seokcheon Lee
Recent analyses combining DESI DR2 BAO, Planck CMB, and Pantheon+ SNe have reported mild deviations from the \LambdaCDM model. A central challenge is to determine whether these dev…
Controlled Ensemble Null Tests of Dynamical Dark Energy Hints: Single-Probe Recovery of CDM with BAO, Compressed-CMB, and SNe Mocks
Seokcheon Lee
Recent combined cosmological analyses have reported mild apparent departures from the cosmological-constant equation of state. We perform controlled ensemble null tests using obser…
Geometric Interpretation of the Redshift Evolution of H_0(z)
Seokcheon Lee
Recent analyses of the Master Type Ia supernova (SN Ia) sample have revealed a mild redshift dependence in the inferred local Hubble parameter, often expressed as tilde{H}_0(z) = H…
Comparing LambdaCDM, wCDM, and w0waCDM models with DESI DR2 BAO: Redshift-Resolved Diagnostics and the Role of rd
Seokcheon Lee
We reanalyze DESI DR2 baryon acoustic oscillation (BAO) measurements to compare LambdaCDM, wCDM, and w0waCDM. Using DM/rd, DH/rd in seven redshift bins, we reconstruct the covarian…
