Quasars and cosmology.
Abstract
This paper challenges the quasar evolutionary theory if the existence of a positive cosmological constant is accepted. The general thermodynamical model of the relativistic universe compatible with existence of isotropic cosmological background radiation parametrized by the Hubble constant, density parameter, and cosmological constant is discussed, and the quasar data is statistically analyzed using a Hubble test which takes the nonlinearity and the observation selection effects into account. The physical homogeneity of the quasar hypothesis was tested spectroscopically, and cosmological tests applied by BurbidgeCrowneSmith (1977), and a nonlinear Hubble test provided a model based only on optical data and the nonevolutionary hypothesis. This model agrees with galactical data and satisfies the radiosourcediameter test. It is concluded that this thermodynamical model agrees with current data, and postulates that the quasar redshift is cosmological and the matter distribution is largescale spatially homogeneous and isotropic.
