Cosmological constraints on Λ(t)CDM models

Problems with the concordance cosmology Λ CDM as the cosmological constant problem, coincidence problems and Hubble tension has led to many proposed alternatives, as the Λ ( t ) CDM, where the now called Λ cosmological term is allowed to vary due to an interaction with pressureless matter. Here, we...
