This research aims to explore the consequences of spectral renormalization group flow in history-dependent gravity on cosmological structure formation.
Conducted an RG analysis leading to running effective gravitational coupling.
Performed a Markov Chain Monte Carlo (MCMC) analysis using 14 measurements of the growth rate observable across redshifts.
Assessed growth suppression dynamics compared to the ΛCDM model.
Identified a running effective gravitational coupling with significant implications for structure growth.
Improved model fit by Δχ²≈38 as compared to ΛCDM with free σ8 parameters.
Predicted a redshift-dependent luminosity distance deviation of dLGW/dLEM≈0.96 at z=1, testable by future detectors.
