Abstract
The possibility of using a Friedmann-Lemaître model with a non-zero cosmological constant γ is investigated on the basis of analyses of the RATAN-600 and 87GB radio surveys and optical constraints. A zero deceleration parameter and critical matter density are features of the model. The model is in agreement with current observational data, including estimates of the age of the Universe, Hubble constant measurements, and the Θ - z relation. A value for the cosmological constant is determined and its physical nature discussed.
