Abstract

We confront Yukawa modified cosmology, proposed in Jusufi et al. [arXiv:2304.11492], with data from Supernovae Type Ia (SNe Ia) and Hubble parameter (OHD) observations. Yukawa cosmology is obtained from a Yukawa-like gravitational potential, with coupling parameter a and wavelength parameter., which gives rise to modified Friedmann equations. We show that the agreement with observations is very efficient, and within 1s confidence level we find the best-fit parameters lambda = ( 2693(-1262)(+1191) ) Mpc, alpha = 0.416(-0.326)(+1.137) , and a graviton mass of m(g) = ( 2.374(-0.728)(+2.095) ) x 10(-42) GeV. Additionally, we establish a connection between the effective dark matter and dark energy density parameters and the angular radius of the black hole shadow of the SgrA and M87 black holes in the low-redshift limit, consistent with the Event Horizon Telescope findings.
