Cosmological Constraints from Compact Radio Source Angular Size versus Redshift Data
We use the Gurvits, Kellermann, & Frey compact radio source angular size versus redshift data to place constraints on cosmological model parameters in models with and without a constant or time-variable cosmological constant. The resulting constraints are consistent with but weaker than those determined using current supernova apparent magnitude versus redshift data. Subject headings: cosmology...
متن کاملCardassian Expansion: Constraints from Compact Radio Source Angular Size versus Redshift Data
The “Cardassian Expansion Scenario” was recently proposed by Freese & Lewis as an alternative to a cosmological constant in explaining the current accelerating universe. In this paper we investigate observational constraints on this scenario from recent measurements of the angular size of high-z compact radio sources compiled by Gurvits and coworkers. We show that the allowed intervals for n an...
متن کاملTight cosmological constraints from the angular-size/redshift relation for ultra-compact radio sources
Some years ago (Jackson and Dodgson 1997) analysis of the angular-size/redshift relationship for ultra-compact radio sources indicted that for spatially flat universes the best choice of cosmological parameters was Ωm = 0.2 and ΩΛ = 0.8. Here I present an astrophysical model of these sources, based upon the idea that for those with redshift z > 0.5 each measured angular size corresponds to a si...
متن کاملCosmological Constraints from Hubble Parameter versus Redshift Data
We use the Simon, Verde, & Jimenez (2005) determination of the redshift dependence of the Hubble parameter to constrain cosmological parameters in three dark energy cosmological models. We consider the standard ΛCDM model, the XCDM parameterization of the dark energy equation of state, and a slowly rolling dark energy scalar field with an inverse power-law potential. The constraints are restric...
متن کاملThe “ angular size – redshift ” relation for compact radio structures in quasars and radio galaxies ?
We discuss the “angular size – redshift” relation for compact radio sources distributed over a wide range of redshifts 0.011 ≤ z ≤ 4.72. Our study is based on a sample of 330 5 GHz VLBI contour maps taken from the literature. Unlike extended source samples, the “angular size – redshift” relation for compact radio sources appears consistent with the predictions of standard Friedmann world models...
