The integrated Sachs–Wolfe effect in f(R) gravity

YC Cai, B Li, S Cole, CS Frenk… - Monthly Notices of the …, 2014 - academic.oup.com
We study the late-time integrated Sachs–Wolfe (ISW) effect in f (R) gravity using N-body
simulations. In the f (R) model under study, the linear growth rate is larger than that in …

Redshift-space distortions in f(R) gravity

E Jennings, CM Baugh, B Li, GB Zhao… - Monthly Notices of the …, 2012 - academic.oup.com
We use large-volume N-body simulations to predict the clustering of dark matter in redshift
space in f (R) modified gravity cosmologies. This is the first time that the non-linear matter …

Constraining models of f (R) gravity with Planck and WiggleZ power spectrum data

J Dossett, B Hu, D Parkinson - Journal of Cosmology and …, 2014 - iopscience.iop.org
In order to explain cosmic acceleration without invoking``dark''physics, we consider f (R)
modified gravity models, which replace the standard Einstein-Hilbert action in General …

Signatures of gravity in cosmology

N Frusciante - Physical Review D, 2021 - APS
We investigate the impact on cosmological observables of f (Q)-gravity, a specific class of
modified gravity models in which gravity is described by the nonmetricity scalar, Q. In …

The non-linear matter and velocity power spectra in f(R) gravity

B Li, WA Hellwing, K Koyama, GB Zhao… - Monthly Notices of …, 2013 - academic.oup.com
We study the matter and velocity divergence power spectra in af (R) gravity theory and their
time evolution measured from several large-volume N-body simulations with varying box …

The Lyman α forest in f(R) modified gravity

C Arnold, E Puchwein, V Springel - Monthly Notices of the Royal …, 2015 - academic.oup.com
In this work, we analyse the Lyman α forest in cosmological hydrodynamical simulations of
Chameleon-type f (R)-gravity with the goal to assess whether the impact of such models is …

Constraints on gravity through the redshift space distortion

L Xu - Physical Review D, 2015 - APS
In this paper, a specific family of f (R) models that can produce the Λ CDM background
expansion history is constrained by using the currently available geometric and dynamic …

Measuring cosmic bulk flow with Pantheon catalogue in perturbed f(R) gravity

M Yarahmadi, A Salehi… - Monthly Notices of the …, 2024 - academic.oup.com
This study investigates the cosmic bulk flow through an analysis of luminosity distance
variations in a perturbed Friedmann universe governed by f (R) gravity. The Hubble …

Galaxy–galaxy weak gravitational lensing in f(R) gravity

B Li, M Shirasaki - Monthly Notices of the Royal Astronomical …, 2018 - academic.oup.com
We present an analysis of galaxy–galaxy weak gravitational lensing (GGL) in chameleon f
(R) gravity–a leading candidate of non-standard gravity models. For the analysis, we have …

Dispersion of growth of matter perturbations in gravity

We study the growth of matter density perturbations δ m for a number of viable f (R) gravity
models that satisfy both cosmological and local gravity constraints, where the Lagrangian …
