Euclid preparation LXXI. Simulations and nonlinearities beyond $\hat{\mathsf{I}}›$CDM. 3. Constraints on $f(R)$ models from the photometric primary probes

Euclid Collaboration, K. Koyama, S. Pamuk +275

We study the constraint on $f(R)$ gravity that can be obtained by photometric primary probes of the Euclid mission. Our focus is the dependence of the constraint on the theoretical…
