AbstractTo investigate whether f(R) gravity can relieve current H0 and sigma 8 tensions, we constrain the Hu-Sawicki f(R) gravity with Planck-2018 cosmic microwave background and redshift space distortions observations. We find that this model fails to relieve both H0 and sigma 8 tensions, and that its two typical parameters log10fR0 and n are insensitive to other cosmological parameters. Combining the cosmic microwave background, baryon acoustic oscillations, Type Ia supernovae, cosmic chronometers with redshift space distortions observations, we give our best constraint log10fR0<-6.75 at the 2 confidence level.
