Cosmic chronometers, Pantheon+ supernovae, and quasars favor coasting cosmologies over the flat $\Lambda$CDM model

Peter Raffai, Adrienn Pataki, Rebeka L. Böttger +2

We test and compare coasting cosmological models with curvature parameters $k=\left\{-1,0,+1\right\}$ in $H_0^2{c}^{-2}$ units and the flat $\Lambda$CDM model by fitting them to cos…
