Cosmological Constraints from Compact Radio Source Angular Size versus Redshift Data
Gang Chen, Bharat Ratra
Abstract
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.
