A Prediction for DESI Full-Shape: Increasing Tomographic Trend
Eoin Ó Colgáin, M. M. Sheikh-Jabbari
To confirm CDM deviations are due to missing physics (not systematics), one should demonstrate that the model fitting parameters exhibit qualitatively similar redshift drift acr…

Redshift Dependence of Dipole in Pantheon+ Supernovae
M. H. Jalali-Kanafi, E. Ó Colgáin, S. Pourojaghi +1
We examine the dipole structure in the local cosmic expansion rate using the Pantheon+ compilation of Type Ia supernovae. We reconstruct directional maps of across the…

Do high redshift QSOs and GRBs corroborate JWST?
Eoin Ó Colgáin, M. M. Sheikh-Jabbari, Lu Yin
The James Webb Space Telescope (JWST) is reporting massive high redshift galaxies that appear challenging from the CDM perspective. Interpreted as a cosmological problem, this n…
