Abstract:

The authors discuss the large scale redshift distribution of QSOs to determine their evolution and reality of the apparent cut-off in their distribution for redshift z greater than or equal to 2.3, in the relativistic cosmological model with zero cosmological constant and with deceleration parameter q sub zero 1. The authors do not discuss the distribution in the Lemaitre models which were introduced in 1967 Petrosian et. al. and have been reviewed recently Petrosian and Salpeter 1970. In a recent article Petrosian 1970 the authors have shown that the density evolution derived by Schmidt 1968 from the data on 33 3CR quasi-stellar radio sources QSRs cannot continue beyond z approximately equal to 2.2. In the report the authors discuss possible evolutions of sources for z greater than 2.2, then based on these models the authors calculate the contribution of QSRs to the radio source counts. Author
