The Amplitude-Growth Degeneracy and Implied $A_{s}$ Diagnostic for Background-Inert Modified Gravity

Ameya Kolhatkar, P. K. Sahoo

We prove that any background-inert perturbative coupling $λ$ in coincident $f (Q)$ gravity exhibits a degeneracy with the clustering amplitude $σ_{80}$ , when using compressed C…

Beyond the Cosmological Constant: Breaking the Geometric Degeneracy of $f (Q)$ cosmology via Redshift-Space Distortions

Ameya Kolhatkar, P. K. Sahoo

We present a rigorous theoretical and observational analysis of the Hybrid $f (Q)$ class of models by including the late-time modifying $1/ Q$ term. After deriving strict viabili…
