Sigma-8 tension is a drag

V Poulin, JL Bernal, ED Kovetz, M Kamionkowski - Physical Review D, 2023 - APS
Measurements of weak gravitational lensing at low redshifts (z≲ 0.5–1), quantified by the
parameter S 8, favor weaker matter clustering than that expected from the standard Λ cold …

Cosmological analysis of three-dimensional BOSS galaxy clustering and Planck CMB lensing cross correlations via Lagrangian perturbation theory

Going beyond the galaxy power spectrum: An analysis of BOSS data with wavelet scattering transforms

G Valogiannis, C Dvorkin - Physical Review D, 2022 - APS
We perform the first application of the wavelet scattering transform (WST) to actual galaxy
observations, through a WST analysis of the BOSS DR12 CMASS dataset. We included the …

Cold New Early Dark Energy pulls the trigger on the H 0 and S 8 tensions: a simultaneous solution to both tensions without new ingredients

JS Cruz, F Niedermann, MS Sloth - Journal of Cosmology and …, 2023 - iopscience.iop.org
In this work, we show that the Cold New Early Dark Energy (Cold NEDE) model in its original
form can solve both the Hubble tension and the S 8 tension without adding any new …

A comparison of template vs. direct model fitting for redshift-space distortions in BOSS
